I've got an older Savage 110 that I pieced together from random parts. I didn't have a front action screw, so I ordered one from Brownells. I threaded it in, set my wrench, and started torquing. Around 25" lbs the allen bit spun free and rounded out the slot. I've ordered a total of 3 screws now, used different bits (same size, different makes) and all of them have rounded out at less than 30" lbs. I've checked the wrench calibration and used the bits on the rear action screw as well as the screws of another Savage 110. The only screws that I am having problems with are the ones from Brownells (which I believe to come from Savage?). Is this a common problem? All of the other screws that I've messed with will take up to 60" lbs with no issues. Brownells has replaced them all with just a phone call, but I have no use for screws that can't be torqued.... What is a better source for this type of fastener? I have to believe that I'd be getting the same thing if I ordered from Savage, but that's just a hunch.
