Lucy R. ★★★★★

Used a few of these in a jig I'm building and the black oxide finish makes them slide into place without any galling on the threads. The partial thread gave me just enough grip for the 6mm plate I was clamping, and the hex socket seated perfectly with a 2mm driver. Solid quality for the price, espec

Olivia F. ★★★★★

Got these for a small jig I was building and the flat head sits perfectly flush, no filing needed. The black oxide finish looks clean and the 10.9 hardness feels sturdy for precision work.

Emma ★★★★★

The partially threaded shank on these M3 screws made aligning them in my jig fixture much easier than fully threaded ones. For a 400-count bag of 10.9 alloy steel with black oxide, the price is solid for production work.
