Optic Install Questions

[ES13Raven]

I'm installing an SRO onto my Staccato P DPO with a CHPWS plate. I bought a Fix-it-Sticks torque kit as well.

 

1. Which is best for cleaning & prepping threads? Acetone? Alcohol? Brake Cleaner?

2. Which thread-locker do you recommend for the plate screws? (Dawson says loctite red 262, CHPWS says VC-3)

3. How much torque on the plate screws?

4. Which threadlocker do you recommend on the optic screws?

5. How much torque on the optic screws? (SRO manual says 15 inch-pounds)

 

Thanks!

I use alcohol and Loctite Primer.    Then I use Loctite Blue on  all threads.  If you use the primer, you have a very limited amount of time to get the screw in an torqued.  So I mount the plate/sight, then remove one screw at a time, prime, dry, Loctite and install.  Use Blue Loctite.  If you do every thing correctly, it will never move.

Brake cleaner or acetone, and compressed air for thread cleaning.

 

Loctite 222 (purple) on M3.

Loctite 243 (blue) on everything else.

 

1NM on M3 into ally (pretty much red dot to frame mount stuff)

1.5NM on M3 into steel

2NM on M4 into steel (grip screws generally)

 

Purple loctite is specifically made for fine threads, and I found it works better than blue.

Dawson replied to these questions:
 

1. Clean with 1st choice: acetone or lacquer thinner, 2nd choice alcohol, 3rd brake cleaner.
2. When we include the thread locker in a kit, we include Loctite 242.
3. 25 in/lbs
4. Loctite 242
5. Use the Trijicon recommendation.
