Ava Z. ★★★★★

Needed a full thread of these for a jig I'm building and every single one seated cleanly with no stripped heads or stubborn starts. The thermal black oxide looks uniform and the hex socket drive held the wrench perfectly on all 100 pieces.

Olivia N. ★★★★★

The black oxide finish on these screws is exactly what I needed for a tooling jig project, and they threaded smoothly into pre-tapped holes without any binding. The flat head sits flush like it should, and the hex drive held up well to my wrench.

Elizabeth ★★★★★

I needed some quality fasteners for a jig I’m building, and these alloy steel screws threaded in smooth and held tight. The black oxide finish looks clean and seems durable.
