Olivia M. ★★★★★

The black oxide finish on these screws is slick and uniform, not a single one had a ding or burr when I opened the pack. I needed a full 50 for a tooling fixture and every thread cut cleanly on the first pass, which is rare at this price point.

Ella C. ★★★★★

Used these to mount a jig plate on my mill table, and the hex socket drive made installation quick with a ball-end allen key. The black oxide finish looks clean and seems resistant to light rust after a few days in the shop. Overall, solid quality for the price.

Ella S. ★★★★★

I needed some heavy-duty fasteners for a jig I’m building, and these M12 socket cap screws feel rock-solid with the hex drive seating perfectly in my tool. The 55mm length and fully threaded body gave me exactly the grip I needed for the assembly.
