Lily D. ★★★★★

The black oxide finish on these screws is slick and uniform, no flaking when I torqued them down on a jig. That 1-7/16" length was exactly what my fixture needed, and all 100 threaded clean without a single dud.

Evelyn ★★★★★

These bolts fit perfectly into my milling machine's t-slots, and the black oxide finish looks clean while resisting chips and coolant. The threads are consistent all the way down, so no binding when tightening with a hex key. Really solid for the price, especially if you need a hundred for jigs or f

Eli M. ★★★★★

Pulled these out of the package and the black oxide finish looks even better in person—no rough edges on the threads. They seated cleanly into my jig with an Allen wrench, and the fully threaded length gave me just the grip I needed without any wobble.
