Michael D. ★★★★★

The black oxide finish held up perfectly during assembly, no flaking or stripping on the first dozen I used. Just the right length for securing brackets on a fixture table.

Amelia ★★★★★

Used a full hundred of these on a jig build this week and not a single one stripped or rounded out. The alloy steel feels properly tough, and the black oxide finish leaves zero oily residue on your fingers when you're handling them. Threads cut clean into every tapped hole I ran them into.

Joseph ★★★★★

The black oxide finish on these 1/4-28 screws held up perfectly during assembly, no chips or flakes. I used them for a precision jig and the hex drive seated cleanly every time. A solid choice for anyone needing reliable socket cap screws.
