Emily W. ★★★★★

I needed a batch of flat head socket cap screws for a jig I'm building, and these fit perfectly in the countersunk holes. The alloy steel feels solid, and the black oxide finish should resist rust well in my shop. Good value for a hundred pieces.

Richard P. ★★★★★

The black oxide finish on these screws is holding up perfectly so far with no rusting, even in my humid shop. Flat head design sits flush in my aluminum jig plates without any interference. Exactly what I needed for precision fixture work.

Leo ★★★★★

I needed a full box for a batch of jigs I’m building, and the black oxide finish held up well through several test fits without any chips. The hex socket drive gave me a solid grip even in tight spots, which saved me from stripping a single head.
