Friendly Neighbor –
Great steel and treated screws.
These are a must have for anyone that has a fair amount of guns and optics and you swap them around or even mount them once but this as we all know that actually shoot, screws break, fall out, or our optics donât come with the correct screws for our weapon system. They were great for replacing a screw that snapped at about 5 inch pounds torque, while the originals were said to be heat treated, these from monstrum actually seem to be. Theyâve done 15 inch lbs to 25 inch lbs without issue.

CTS red dot mount screws
I need two specific mounting screws for my CTS red dot sights. They were packaged, and labeled, which made it easy to sort the exact screws I needed for my mount. Highly recommend!

Nice assortment of common RMR screw lengths and thread pitches
Nice assortment of RMR screw lengths and thread pitches (especially the common 6-32 thread pitch used in many RMR mounts). Comes with blue thread locker pre-applied but I always recommend a new layer. Head utilizes the commonly used #10 Torx driver head and the nitrite finish appears to be durable (time will tell if it is prone to corrosion). Was able to torque to 15 lbs/in without any problems so far. Screws come in sets of three and are clearly marked in individual small zip lock bags of three each. Nice to keep on hand for those situations where you might lose a screw when changing out your RDS for whatever reason.
What? –
Screws stripped well before reaching torque specs for optic
If I could give these less than 1 star, I would. They arrived today and I immediately installed the RMR screws onto my G19 plate. I applied 10lbs according to the optic instructions and the first screw immediately started stripping as soon as as I hit around 8lbs. I stopped and backed it out and it was indeed stripped. Tried the other two of the same size that came in the pack and they ALL striped at 8 lbs. absolutely ridiculous. What are these made out of? Cast junk metal? Do NOT trust your life to these.
