RE: stripped allen screw
it's probably a 10-32 thread or so, either way, measure the hole. go to the hardware store and ask to see a tap conversion chart. buy a tap (about 8 bucks) and the corrosponding Hex head cap screw. In like flint. Make sure you use some oil and take your time when tapping. Good luck

RE: stripped allen screw
If it's stripped really bad, to the point where you can't rethread it to the original size, you might could find a machinist that will install a helicoil in the hole for you. You could buy a kit with all the tools plus the correct length helicoil and do it yourself, but I don't have a clue what the kits areselling for these days. Around a hundred bucks, if I was to make a guess.
Another option, if you've got enough metal around thehole to do it,would be to drill it out and retap to the next bigger size. If it's a 10-32, you'd be going to 1/4-28. You'd also have to drill out the clearance hole in the mating partto get the screw into the threads. That would take a #3 drill (.213")for the screw hole and a letter F drill(.257")for the clearance hole.

RE: stripped allen screw
shouldn't be any need to helicoil., and my gues is that would be a Tiny helicoil at that. hard to find em yourself that small. Just go with the drillbit that takes off the least amount of material to clean it out and tap it with the appropriate size

I said "If it's stripped really bad, to the point where you can't rethread it to the original size..." then helicoil would be an option. A 10-32 isn't exactly a tiny size either. Get down into the 2-56 range and then we can talk tiny.I spent 15 yearsas an aerospace machinist so I know a little something about retapping aluminum.

For some reason I'm feeling a real need to start referring to you as Mr. ...
Are you implying that the there's some truth to the advertising slogan "space age technology" in the archery world. That's why the stuff costs so much.

RE: stripped allen screw
Some truth? Well, yeah. Especially since compounds themselves are space age technology. After all, compounds weren't patented until 11 years after the Soviets launched Sputnik and only a year before Neil Armstrong set foot on the moon. But stuff only costs so much because so many people are willing to pay what the manufacturers want to charge for it.

. Some have the mindset that if you don't put a torque wrench or a cheater bar on it, it's not tight.sorry for being sarcastic, I've done too.
, but not in a long, long, long, time. I've learned my lesson, the hard way.
