Customer Reviews (4.2 / 5 · 5 reviews)

Sebastian R. ★★★★★

The black oxide finish on these screws held up perfectly against the cutting oil in my lathe. They seated smoothly with a hex key and the threads caught cleanly in my steel fixture.

Victoria D. ★★★★★

Used a full pack on a custom jig build and every single one seated perfectly in the tapped holes. The thermal black oxide finish feels tough and should hold up well against shop grime. For a 5-inch alloy steel screw at this price, you can't beat the threading consistency.

Thomas ★★★★☆

The black oxide finish on these screws looks clean and professional, and the hex drive seated solidly in my socket driver without slipping. They held up fine for adjusting some tooling jigs, though I wish they came in larger quantities for bigger projects.
