MoNsTeR Posted October 26, 2012 Share Posted October 26, 2012 I've been planning to replace the screws on my backup open gun so I can add a thumb rest, then I saw Bob Londrigan's piece in the latest Front Sight, and I got to thinking. Bob advocates Blue for scope mount screws, but the last time I tried using Blue it came loose so I had been planning to use Red. What do y'all use?

SPRSkip Posted October 26, 2012 Share Posted October 26, 2012 I use blue. Red is typically for anything you don't ever plan to remove. Sent from my SCH-I535 using Tapatalk 2 Link to comment Share on other sites More sharing options...

Sarge Posted October 26, 2012 Share Posted October 26, 2012 Blue here as well. If it failed it was probably a contamination issue when it was applied. The slightest amount of oil or cleaning solution will kill it dead. Link to comment Share on other sites More sharing options...
warpspeed Posted October 26, 2012 Share Posted October 26, 2012 Blue here as well. If it failed it was probably a contamination issue when it was applied. The slightest amount of oil or cleaning solution will kill it dead. Very true. I have found cleaning both the fastener and the hole with isopropyl alcohol works best.

caspian guy Posted October 27, 2012 Share Posted October 27, 2012 (edited) Red... If I want to remove it use a soldering iron on the screw from inside the dust cover. Edit to add: Just to be clear, like the guy below I was talking about the mount to frame screws. Not the C-More to mount screws.

Aircooled6racer Posted October 27, 2012 Share Posted October 27, 2012 Hello: I use red on the mount to frame screws and blue on the C-More screws. I also just use steel screws not stainless steel ones. Thanks, Eric Link to comment Share on other sites More sharing options...
bobert1 Posted October 28, 2012 Share Posted October 28, 2012 There is a good write up in the new Front Sight magazine about which to use and where. Link to comment Share on other sites More sharing options...
jriera Posted October 28, 2012 Share Posted October 28, 2012 Mount to frame RED .. C-More screws BLUE Link to comment Share on other sites More sharing options...
Whoops! Posted October 28, 2012 Share Posted October 28, 2012 Red, I've never had good luck with blue. If I need to remove it and the torx wrench doesn't work, time to either cut a deep flat head spot in the screw or drill out the screw. I've always been able to remove the C-more screws with a regular wrench after red loctiting them since the head and wrench are so big, much less prone to stripping than the mount-to-frame screws.

SLM Posted October 28, 2012 Share Posted October 28, 2012 Red does not belong on those little screws. Blue is what you want. Just apply it properly. If you have to use red on a 5-40 screw you aren't applying it correctly. If it's done right, the low strength purple is more than sufficient for a couple of 6K to 8K round seasons.

splashdown Posted October 29, 2012 Share Posted October 29, 2012 When I had my open STI, I used the red gel type. I would fire up the propane torch and heat the screw heads to be able to remove them. Link to comment Share on other sites More sharing options...
kineteks Posted October 31, 2012 Share Posted October 31, 2012 I've used all three, purple, blue & red. While as a rule, for 4-40 & 5-40 threads, I would normally use purple I have found over time that nothing short of red prevents loosening of those screws until I want to take 'em out. I have always started with clean, grease-free dry threads so I don't know if its a combination of heat and shock or what but, less than red = loose for me. BTW there are a large number of Loctite "reds" some are high temp, some have high breakaway torque then a lower prevail (effort to turn after the screw's broken loose)torque and some go the other way. I use 262 which has a moderate breakaway torque, a higher prevail torque and loses 50% of it's strength at 150C, ...a little bit of heat with a small torch and the screws come right out.

blaster113 Posted November 3, 2012 Share Posted November 3, 2012 red for mount to frame, blue for Cmore to mount Link to comment Share on other sites More sharing options...
cybrosh Posted November 12, 2012 Share Posted November 12, 2012 Red. Just use a tiny bit. I use less than a drop. It will keep it in place for a long time and you'll be able to open it. Link to comment Share on other sites More sharing options...
Front Man Posted November 15, 2012 Share Posted November 15, 2012 It isn't the color, it's the number. I think I am using 222 MS (it is red) right now. There is also a primer Loctite suggests you use. A propane torch flame on the head of the dust cover screws will loosen them. That's what I do anyway.

Foxbat Posted November 16, 2012 Share Posted November 16, 2012 A propane torch flame on the head of the dust cover screws will loosen them. I apply the flame to the screws ends, from the inside of the dust cover, this way it has to heat less metal, because the very end of the screw is where the action is.

SKR Posted November 17, 2012 Share Posted November 17, 2012 I use to work at a Suzuki dealership and found their version of thread lock to work very well. It dries quite a bit faster and very user friendly about prepping the screw holes. 3 hours total dry time. Makes for a quick fix at a match. Also I second the soldering iron technic, hold it to the screw (if it protrudes through use the threaded end) I take my snap on butane soldering iron with me to big matches. Some how I always find something to do. Link to comment Share on other sites More sharing options...
