Customer Reviews (4.8 / 5 · 5 reviews)

George B. ★★★★★

The black oxide finish on these screws held up perfectly during assembly, no galling or binding. They seated flush in the counterbore without any wobble, which was crucial for my tooling setup.

Lucy H. ★★★★★

Used these for a jig fixture I’ve been building and the hex socket drive made seating them flush a lot less fiddly than slotted heads. The thermal black oxide coating has held up fine so far under a bit of shop grime, no rust spots after a week.

Andrew ★★★★★

The black oxide finish on these screws gives them a nice grip when tightening, and the flat head sits flush in my fixture plate. They threaded smoothly into tapped holes on my drill jig without any binding, so I’ll be ordering more for upcoming projects.
