YYHJ 12 Sets KeyMod Rail Screws

Shipped as advertised, good quality, as described.

do what they're supposed to do i guess, but not very well. the steel of the screws is soft. if you torque them down, the screw head will strip. happened several times so far. and if i dont torque them down, that rattle loose as the weapon fires, even w threadlock.

These work for about a million things. It's a screw with a through nut that latches.

Heads are soft. Just hand tighten with supplied Allen wrench and I could feel the head striping.

They get the job done. Bought two sets of bits trying to use these properly (with a torque driver) and no standard metric or imperial size will fit these properly. Therefore all I could do was bring them to about 20lbs and hand tighten with the supplies wrench until they felt snug but not like they would bite through key holes. I shouldn’t have to worry about that though, it should have been simple as taking it to the right weight and being done, instead of worrying about over and under tightening, do yourself a favor and go find some stock bolts; it’s worth the peace of mind.

Gets the job done, but very easy to strip the threading if you overtighten. Awkward fit on my rail, but it might just be the handguard on my gun.

Great with lock tight still useing todate.

Cheap and functional
