Andrew P. ★★★★★

Used these for a precision jig build and the flat head seats perfectly flush every time, which saved me a ton of cleanup. The black oxide finish held up nicely without any galling when I torqued them down. Fasteners were consistent out of the box, no duds in the batch.

Jason N. ★★★★★

The hex socket drive made these really easy to install in tight spots on my tooling fixture. The black oxide finish looks clean and seems durable so far.

Robert ★★★★★

Used a few of these for a jig I'm building and the flat head sits perfectly flush, which is exactly what I needed. The black oxide finish seems durable and hasn't scratched during installation.
