Serious Student made a good suggestion. If you consider the economics of it, that 500 count box is ~$10 ($0.02/pin). Any 1 roll pin will cost $0.50 @ WOA, $2.00 @ SA, and the cost of one that comes in a LPK is probably a little more than SA for someone to put it in a bag with all of the other parts. As IG confirmed, roll pins should be discarded once they are removed once.
I could be wrong, but I believe the socket head cap screws for the gas key are supposed to be "grade 8". Common cap screws are usually "grade 5". At full specified torque a grade 5 screw will be over stressed.
In addition, I would only use "made in USA" screws for this part. A couple of good brands are Allen and Unbrako.

Years ago when I was designing medical equipment an Unbrako applications engineer told me that their hex keys were designed to shear off near the screw head before the fastener could over torqued. Different grades of cap screws used different keys. This of course does not apply to the keys used with various torque wrenches.

I use these in the range and gear bags to carry spares etc..Work well to protect items in that application.

I have a couple of those Plano boxes, and use them for Glock pistol parts as well.
I do want to get a couple that do not have the adjustable dividers. Some of those roll pins are so tiny, they can migrate between the dividers. The gas tube roll pins are a good example of what I had to carefully empty a box to find.

Yeap,been there done that.
For small roll pins and such that I would have a quantity on hand of, I keep them in small storage tubes similar to these.

Prevents fumbling around trying to fish the roll pin out of a parts tray and or loss.Pull the cap and dispense however many needed at the time.The tubes can be cut to length desired to save space,and labeled.
Plus the added advantage it provides in a bit more corrosion protection,and drop right in those dry boxes.

Neat - I had never considered something like those. There's a Hobby Lobby not far from here, I'll snag some of those.
Thanks for the tip!
