I use locktite on the screws mounting the scope base to the gun.  Those are very small and you can't really get much torque without risking stripping the threads.   I don't locktite the screws that mount the scope. 

May not be right but it's what I do.

Most mounts have torque specs for screws... usually inch/pounds. The way you don't strip the threads is using a torque driver, to the right spec.

Put blue Loctite on the threads, torque, then good to go. Don't do red, blue is good enough for most firearm purposes.

Seeing a lot of people recommend using a torque driver lately. Is there one you recommend? I saw a few in the $50 range doing a quick search online.

I use a Wheeler torque driver at home and have a Borka for the range.

I got a Husky one from Home Depot. Craftsmen from Sears is another option... which I have a larger one for automotive stuff.

Wouldn't by a no-name brand.

Just make sure its INCH POUNDS.  Most of the sears/hd stuff is auto repair for torque in ft lbs.

Conversions can be found online but get a 1/4" tq wrench. Small enough numbers to maintain some level of accuracy. Using a 1/2" torque wrench with big ftlb intervals may not be so accurate.

This is what I use. Works very well.

Yep, which is why I said torque driver... never saw one in foot/pounds. Uses standard screwdriver bits.

The one bhunted posted is another good option.

I very recently purchased this torque wrench. I plan to use it this weekend when I mount my scope to my new Ruger Precision Rifle.  I am confident I will be happy with this torque wrench.  Ironically, I have used ft/lbs torque wrenches for automotive work for the last 40+ years but never owned an inch/lbs one.  Better late than never.  It will also help if I ever buy an RMR for my Glock 34 MOS.

I remember someone pointing out not to use loctite on polymer, only metal to metal. Said it was on the package warnings. Anyone know why?

Loctite doesn't work on metal-to-plastic. It's only for metal-to-metal. If you need metal-to-plastic, you can use a drop of CA glue (crazy glue) That's what is used on my RC helicopters and cars if it's really needed. Otherwise, the friction from the plastic on the screw should be enough to hold it.

Actually, Purple Loc-Tite is better suited for most firearms applications.

[maintenanceguy 510]

The manufacturer's recommended torque doesn't guarantee the screws can't work themselves loose.  Torquing the screws is good practice but adding a drop of locktite isn't going to cause any problems and it might prevent some.

I thought purple was for hydraulic fitting threads. Thicker than blue or read - almost a gel.

Loctite is a brand of adhesives... and there are multiple types.

The black 380 Loctite bonds metal and polymer. Commonly used on the "castle nut" on the KelTec SUB-2000.

It is for fine threads and is less tenacious than blue.
