When were 9310 bolts first introduced?
Early on there were some issues with properly heat treating that led to breakage. Has that since been corrected? If so when?
Some say a properly heat treated 9310 is better than mil-spec C-158?
C-158 bolts are available in both phosphate and nitride, it appears all 9310 bolts are nitride only?
Has Crane tested 9310 bolts with the latest heat treatment processes?
Are there any drawbacks to a properly heat treated 9310 bolt?
Are 9310 bolts still considered unproven?
