Mia I. ★★★★★

The hex socket drive on these M2 screws grips the Allen key perfectly, no slipping even when torquing them down in a tight spot. The 316 stainless finish is clean and uniform across the whole 400-piece batch, which I wasn't expecting for the price.

Stella Y. ★★★★★

Installing these in a tight jig was a breeze with the hex socket drive, and the fully threaded length gives great grip. The 316 stainless steel feels noticeably tougher than the standard 18-8 I've used before — perfect for marine gear. Exactly what I needed for precision assemblies.

Joshua J. ★★★★★

Priced under what I expected for 316 stainless, and the 18mm length is spot-on for my jig builds. Threads were clean and consistent across all 400 in the bag, no burrs to fight with.
