Hi Ron, They do. However, sometimes someone (Not me.....) Over tightens the oversized screw and that is really where this new thingee works well.

Anyone ever get or use them ? Ron from Wisconsin At 02:58 PM 1/25/2007, you wrote: List, Here's a way to repair stripped screw holes (Especially if an oversized screw strips) in an aluminum rail that takes less than a minute or two. "Helicoils" is what they are called. (See attached pic.) You drill out the hole and tap it, then insert the little coil which disappears into the tapped threads, and then you're good to go! Maybe this has been shown on CAUT before, I don't remember seeing it. The new screw is actually a machine screw with fine threads so it takes a few more rotations, but this is way better than anything else I've ever tried. The package shows a bolt, but what actually goes in has a Phillips head and looks like a normal screw. Jim Busby RPT BYU -------------- next part -------------- An HTML attachment was scrubbed...
