William ★★★★★

I’ve been using these M3 screws on a small CNC jig project, and the hex socket drive makes them incredibly easy to tighten even in tight spots. The black oxide finish looks clean and feels durable so far.

Victoria U. ★★★★★

Pulled these out of the package and the black oxide finish is uniform and clean, no stray burs. They seated perfectly into my jig plate without any wobble.

Stella K. ★★★★★

Bought a pack of 600 for jig building and the black oxide finish has held up nicely through plenty of clamping cycles, threads cut clean every time. Class 12.9 strength gives me confidence these won't strip under heavy loads.
