f2benny Posted February 18, 2018 Share Posted February 18, 2018 Damn screw in a Cz rear sight rounded out. What options exist? It's a tiny screw so I dont think an easy out is an option. Sent from my SM-G930V using Tapatalk Link to comment Share on other sites More sharing options...
Amra86 Posted February 18, 2018 Share Posted February 18, 2018 I would drill out the old screw. Make sure the bit is small enough not to damage the threads in the sight. After removing the sight, run a tap thru it to remove the rest of the old screw. Link to comment Share on other sites More sharing options...

f2benny Posted February 18, 2018 Author Share Posted February 18, 2018 There nothing above the surface of the sight to grab on to the flush set screw but thanks for the idea Link to comment Share on other sites More sharing options...
open17 Posted February 18, 2018 Share Posted February 18, 2018 You might try driving a torx bit into the rounded out hole. Many times it will grab enough to back out a rounded out allen. Might also soak in Kroil, and a little heat never hurts. Link to comment Share on other sites More sharing options...
BritinUSA Posted February 18, 2018 Share Posted February 18, 2018 Another option is a small Allen wrench with small dab of JB Weld, set up a platform to hold the wrench onto the screw and let it set. It may provide enough grip to unscrew it once it has fully hardened. Link to comment Share on other sites More sharing options...
zombywoof Posted February 19, 2018 Share Posted February 19, 2018 Take a flat punch and tap the top of the screw head. It might push the Hex/flat/torx/philips metal back into a little better shape. Use a new Allen wrench if it's a socket head. That rounded Allen wrench ain't helping you. Link to comment Share on other sites More sharing options...
warpspeed Posted February 19, 2018 Share Posted February 19, 2018 I have had good luck with the Torx bit trick mentioned by Open17 Link to comment Share on other sites More sharing options...
CHA-LEE Posted February 19, 2018 Share Posted February 19, 2018 Try a 1/16th Allen as it’s slightly larger than a 1.5mm. Link to comment Share on other sites More sharing options...
f2benny Posted February 20, 2018 Author Share Posted February 20, 2018 A tap on the screw some penetrating oil and some heat got it out intact so thanks. Sent from my SM-G930V using Tapatalk Link to comment Share on other sites More sharing options...
NHGunowner Posted April 1, 2018 Share Posted April 1, 2018 Sounds like you got lucky, that's excellent. So I'm a lead mechanic at a big car dealer, responsible for a bunch of younger techs. Sooner or later I always get asked, "how do I get this stripped out/broken bolt?" My answer always starts with, "don't wreck it in the first place!" Your best chances of getting something out is using the original intended tool. Heat, oil, vibration, anything. Once you round or break it, options become very limited and it is difficult to even match the torque you have available with an intact head. Allens in particular, benefit from good, hard, sharp edged drivers. The free ones that come with stuff are usually terrible. Link to comment Share on other sites More sharing options...
Don_B Posted April 1, 2018 Share Posted April 1, 2018 Something I use quite often is a small set of left handed drill bits. They work better than an easy out most of the time. Link to comment Share on other sites More sharing options...

Luck2011 Posted April 2, 2018 Share Posted April 2, 2018 (edited) I've done it a few times on the Tanfos drilling is hard because it's so small. Got to make sure you have a GOOD bit and take it very slow, I agree try left hand bits first, Good Luck ! Edited April 2, 2018 by Luck2011 Link to comment Share on other sites More sharing options...
