View Full Version : BCM grip screwdriver size for installation screw.
I have to install a BCM MOD 3 grip and it comes with a regular flat, slotted screw (not the milspec one) and on its website (and BCM CS didn’t even know - I found out via email with them) I need to know the size of the screwdriver end (not the length). There’s a million different screwdriver sizes on Amazon and don’t want to get the wrong size and not have it fit, or be too small and then strip it. Does anyone know the exact flat head screwdriver size/mode that will install the BCM grip installation screw that comes with the grip? Thanks in advance guys.
Spend $3 on a screw with a hex head. I grew tired of chasing slotted screws in grips quite a long time ago.

I've used a good amount of incorrect slotted tips over the years and never had a problem. Yeah... too big is worthless, but that's pretty uncommon.

So what’s the correct size?
Brownells has the correct magna-tip bit that will fit tight into the head of a USGI grip screw. I want to say its a 340 series.
Thanks guys. I figured it out it’s a 5/16” inch flathead at the length of your choosing. I still don’t know why BCM just didn’t stick with the milspec screw. Appreciate all your advice.

their screw is the milspec one. Same as colt, ect.. Schmid provides them with their LPK parts or you can get them from mcmaster-carr.

With their gunfighter MOD 3 grips it’s a flat head screwdriver kind, not the cap screw kind. I just bought the grip alone, not one of their LPK’s. But even still, I don’t know why they still wouldn’t use the 3/16 one.

That’s a great point. I wish they just included them to begin with, so much easier.
The Stanley FatMax 5/16 flathead is perfect for grip screws.

Lets have a reality check. Its the same damn screw for all gunfighter grips and a2 grips

My PSAs all came with the vastly superior and highly preferred allen grip screw. Definitely recommend deep sixing that slotted garbage. Which is exactly what I did with my Colts (screws).

This ^, a hex Allen socket screw and a long hex Allen wrench makes it easy.
So the OP Cane55 has not only asked what screw driver to use here, but also on TOS.
Taking the screw down to the local hardware store to find a screw driver that fits apparently eludes him, and he's willing to pay more than $6.00 to buy one.
Of course I told him on TOS to go to the local hardware store to buy a SS ¼”-28 x 7/8” Allen head screw that takes a Hex Key Size: 3/16" and should cost him less than $2.00.
But no, he's still trying to find a screw driver that fits on two forums.....SMH
So lets go arfcom route instead of getting him the right bit for any USGI spec screw...
Okay then
I suggest taking the lower receiver to a local gunsmith to have them replace the grip. The use of the incorrect driver will surely damage the screw beyond repair, and render the rifle inoperable.....just not worth the risk.

Lol wut? Take it to a gunsmith? We're talking about installing a pistol grip.
Yep, a task that seems to be rather difficult for the OP to accomplish.
Seriously, if the OP doesn't have a variety of driver bits, buying a set of different sizes that also includes Torx and Phillips would be a much wiser purchase than one bit or screwdriver. Naturally, a bit driver that's long enough to reach the screw will also be needed.

I've got numerous slotted grip screws in a bag, but none in my ARs.

Your 100% correct. I scoured the internet and the original milspec is a slotted screw for the pistol grip. I have plenty of tools however I don’t have flathead 5/16” six inch screwdriver, so I didn’t want to use a smaller, loser screwdriver and potentially mar or damage the screw since the build isn’t exactly bottom dollar.

Yeah, I really gotta be missing something, cause I have never had an issue changing grips at all.

Neither have I, and I do it with whatever screwdriver looks close enough to get the job done. I’ve never once thought about what the correct size was. And as far as hex heads go, it’s a lot easier to round one of those out than it would be to jack up the slotted grip screw to the point where you couldn’t still get it out. I’m guessing that’s why the milspec ones are slotted.
I prefer slotted screws for the readily available drivers.
I know nothing about the TDP for this, but I have a #41584 1/4” Craftsman that fits both Colts and BCMs.
Before we judge the OP, let us remember that sometimes things are not quite as obvious as they seem with screwdrivers. For example, many people malign the shitty soft Phillips screws on Japanese motorcycle carb bowls, when the real problem is that the screws are JIS, not Phillips and many among us are too ignorant/stupid to use the correct tool. And I’ve found myself occasionally grinding flatheads to be better fits on slotted screws. Hell, you’ll note that gunsmithing screwdrivers have a totally different shape to the blade than Stanleys and Craftsmans.
A sliver of duct tape or even some folded paper would solve your problems fairly easily. Most do have that lying about or use a BFSD-one with a flat blade of course
I prefer slotted screws for the readily available drivers.Which was my rationalization as to why Colt used (and uses) a slotted screw from the very beginning.
Much more difficult to install in an automated line, so they had to use it for a reason.
As much easier as hex is to install / remove, I've used the slots if that's what it came with. Really no big deal.

I picked up a nice set from the Mac guy that has bits for fasteners I haven't seen.
No Torx Plus though, which sucks as I'm seeing stuff with TP fasteners and had to get a TP20 and TP25.

What size screwdriver did you use when you installed the slotted screws? I got a 5/16”th’s by 6 inches (which is wide enough for the screw, but is a little too thin and rattles up and down). What did/do you use? Thanks.

Can’t argue with that.
FYI - I spoke to BCM and they said they use a 3/8” screw. So there’s the answer. You can use smaller ones to get the job done I suppose, but the exact screwdriver would be a slotted 3/8” (for all other milspec too).

This works well for holding the mil- spec grip screw to get it started.

Do you know the McMaster part # for the grip screw?
Does the locking washer that comes with the BCM grip have a certain way it’s supposed to go - up or down? Before I’d just install it and didn’t think it made a difference but now with all of this technical knowledge I’m learning from you guys I’m worried if I install it upside down & there’s one side that’s specifically made to go into the plastic grip etc. or are they ambidextrous? I’ve looked at both sides with my untrained eyes to death and can’t tell the difference. Thanks in advance for anyone that knows.

You can use blue Loctite, it's just more of a pain in the butt to remove later on if you need to. And the answer to the torque spec question is 35 inch pounds (considering a 1" inch length screw). It's not an official TM listed spec, but it seems to be the sweet spot and I've used it since Bill Alexander posted that number on here quite a few years ago.
Here's a link to that... https://www.m4carbine.net/showthread.php?1921-Pistol-grip-screw
And here's where I reconfirmed the number a few years later... https://www.ar15.com/forums/industry/Pistol-grip-screw-torque-spec-/431-207561/
As Will would say... Get the right tool and a new star washer and get the screw gud-un-tite. There is no torque spec. Its a steel washer digging into plastic ffs.

How long is the thread about buffer weight placement and milspec roll pins? You guys are thorough.

BCM wrote me back about the amount to torque:
“Torque should be no more than 55 in-lbs. We usually recommend install hand tight plus a ¼ to a ½ turn.”
BCM wrote me back about the amount to torque:
“Torque should be no more than 55 in-lbs. We usually recommend install hand tight plus a ¼ to a ½ turn.”
That's a bit on the high side, but less than what Colt listed in their 6940 manual (65 inch pounds)... They are both too high and don't really take into account the fact that they are clamping a thin shelf of polymer IMO.
Most AR manufacturers are just installing the grip screw by hand on their assembly lines with no torque spec, so keep that in mind.

You can get the correct screw and lock washer from Colt through Brownells. I'd imagine that the Colt parts are made here in the USA.

I know, but if you want to stock a box of 25 to have on hand Brownells does not have good pricing. Just got off the phone with McMaster and they dont have a single 1/4 star washer made in USA.
Wonder where manufactures source them?

Yeah, the Brownells prices on anything Colt are not the best. There's Specialized armament and G&R Tactical that usually beat Brownells on prices, but not by much. And G&R never has the Colt grip screws and lock washers.

True, in that case I'd buy them from Specialized Armament because they are likely older stock and more likely made in the USA.
It also appears that the star washer comes with external or internal locking teeth and I see both regularly.
Magpul screws are only 3/4" long and they come with a thread locking patch that eliminates the use of the star washer.
BCM screws are the traditional 1" long Fillister head slotted screw and they use the star washer with the external locking teeth.
SOLGW screws are a 1" long 18-8 stainless screw with a 3/16 hex head that also comes with a thread locking patch and no star washer is needed.

I just swapped my BCM mod 0 for a mod 1 tonight. It had a mod 3 originally. I just grabbed the half rusted pretty big flat head screwdriver from my old tool box and did it in 30 seconds. I tightened it “pretty tight” like I always do. I guess I should’ve checked here first.

I'm not really a fan of the internal toothed lock washers when the clamping surface is plastic (they can grip onto socket head cap screws and burrow right through the grip like a drill of sorts without ever feeling like they are getting tight). However, they are the correct choice for the Fillister head and socket head cap screws.
I'm also not a fan of using the Fillister head and socket head cap screws unless backed by a half inch diameter flat washer. The small diameter heads on those screws just don't offer enough support.
The Magpul screw is great, I just wish they offered it in a 1" inch length version.

If and when you’re paying someone for services you expect the work you’re have done to be done professionally and to be done right. Roll pins are single use and I don’t knowingly use Chinese replacements.

Well that's Interesting (to me), and it's pretty similar to the Magpul grip screw... This may be the perfection in a grip screw that I've been wanting for quite a few years now. :smile: Last I knew they were using a stainless socket head cap screw with locking patch and an internal toothed lock washer. Actually, both of those are still on the Brownells site.

I'm just glad that SOLGW was willing to look into the grip screw (much like Magpul) to update it with modern enhancements, even though it seems like many would argue the worth of doing so.
A2 stock screws could certainly benefit from some modernization as well, but not many outside of the "retro" cloning crowd are using A2 stocks anymore.

Just to add a little fuel to the fire. The best fitting bits for a replaceable bit screwdriver are the ones made by Brownells or Wheeler that were designed for Leupold or Buehler scope rings. They fit perfectly in Magpul or Colt style screws. Brownells part number is 080-430-430WB. I have no idea if Wheeler sells individual bits.

Because the specification defines how the part is made and what assurances there are to guarantee the quality. They do not specify where it shall be made.
(Most "mil-specs" are actually industry specifications based on older military specifications, adopted by the DoD.)

Nothing comes up on either Brownells or Wheelers website with 424-466. It must only be available as part of a set as said above.
SOLGW has come out with a seemingly great screw that does both.
Do we really live in a world where an adult doesn't own a straight screwdriver?
I know, properly fitting screwdriver, etc. Its a grip screw, who cares if it gets a little mangled?

I will not allow an improperly fitting screwdriver anywhere near my grip screws, or any other screw for that matter. A perfect fit is even more important since you can't really see very well what you're doing down inside the grip. And I very much care if the grip screw drive slot gets a little mangled, I've replaced certain parts for things that were even more hidden and insignificant.

I have literally hit the range 12 times with an AR since this thread started. Its not rocket science - screw the grip on and go shooting.

For a few thousand rounds.

I use any of the 3 on the left for grip screws, but I'm in the habit of using the blue handled CDI so I usually just go with it.

You have many nice tools Sir, I like your style.

From one quality tool enthusiast to another, thank you and back at ya! ;)
And it's not that I haven't installed grip screws without a torque screwdriver, I certainly have, but I like to get them to 35 inch pounds. There's been a few times that I thought I did a good enough job just by feel alone, but when I double checked with the torque screwdriver they were slightly below that magical number. Apparently my feel isn't perfect, and I bet most people's estimations are off... I use the torque screwdrivers on buttstock screws too.
I actually bought the Gedore torque screwdriver because it goes up past 40 inch pounds. That's the max range of the CDI and they don't make one that goes higher unfortunately.
The Snap-On torque wrenches are awesome too. The bigger (Ft-Lb) one has a scale from 5 to 75 foot pounds and the smaller (In-Lb) one goes from 40 to 200. And I prefer the fixed heads instead of the ratcheting heads for use with all the extended AR wrench adaptors. It just keeps things in line so I don't have the tool spinning around constantly (minor annoyance, but it bugs me). I'd probably get ratcheting heads if I wanted to work on cars, but for ARs I just prefer fixed.

A bit of a post script - I respect owning quality and correct tools. For a gun owner, buying good tools actually made for firearms is money well spent (screwdrivers/bits particularly). It just seemed the OP was stuck in a loop.

I agree about the OP, he just needs a decent quality screwdriver bit set and it shouldn't be a problem finding a bit to fit most screws. Though you can certainly get carried away with things like this depending on your level of OCD, I know I sure have.
Originally I was only OCD with ARs, but through working on them and putting them together I became just as OCD about the assembly tools.
I know that there are a lot of people that are happy to put an AR together using only a spoon, a couple of toothpicks and a butt vise at their kitchen table, but I just can't fathom that approach. :fie:
