    Loc tite

    I have a Blackhawk 41 mag that I shoot and about every third time out I have to tighten some of the screws. This is a pia as I have to dismount the scope to do it. What loc tite should I be using?

    Before applying make sure you remove any traces of oil from the threads.

    I use acetone or denatured alcohol.

    And a torque wrench. 242 is useless if you don't have the screws tight enough.

    I've always had good luck with Blue 242. From their website:

    Loctite Threadlocker Blue 242 is designed for the locking and sealing of threaded fasteners which require normal disassembly with standard hand tools. The product cures when confined in the absence of air between close fitting metal surfaces. It protects threads from rust and corrosion and prevents loosening from shock and vibration. Loctite® Threadlocker Blue 242 is particularly suited for applications on less active substrates such as stainless steel and plated surfaces, where disassembly is required for servicing.

    Loctite Threadlocker Red 271 is designed for the permanent locking and sealing of threaded fasteners. The product cures when confined in the absence of air between close fitting metal surfaces. It protects threads from rust and corrosion and prevents loosening from shock and vibration. It is only removable once cured by heating up parts to 500°F (260°C).

    Hi, Joe. Can I ask for more specifics? Are you saying that Blue 242 does not hold well (I've never had that problem)? If you've ever had to loosen Red 271 did you have to use heat? I just don't know what "good luck with that" means. Thx.

    I've never had a problem using the blue Loctite. I would try it first before you try anything else. Like mentioned, just make sure the threads on both the gun and screws are clean and oil free.
