John M. ★★★★★

Installed a full row of these in a steel fixture jig this week and the flat head seating is spot-on, sits flush every time. The black oxide finish held up great through a lot of handling without any surface rust. Hex socket drive bites firmly with no stripping even at 1.5 inches of thread engagement

Joshua B. ★★★★★

I’ve been using these flat head screws for securing jig plates on my drill press table, and the thermal black oxide finish has held up well without any rust after several weeks in my damp garage. The hex socket drive made installation quick and easy with a standard Allen wrench.

Joseph L. ★★★★★

The black oxide coating on these screws has held up perfectly during assembly; no chipping or scraping like some cheaper fasteners I've used. They thread smoothly into my jig fixtures without binding. Exactly the quality I needed for precision work.
