Customer Reviews (4.2 / 5 · 5 reviews)

Claire ★★★★★

Third batch of these I've ordered for our jig fixtures, and the hex socket drive makes them a cinch to torque down in tight spots. The thermal black oxide coating has held up through repeated assembly and disassembly without any rust spots.

Alexander ★★★★★

These arrived with a clean, uniform black oxide finish and the hex sockets were perfectly machined—no stripped edges on the first dozen I used. Fit my jig fixtures exactly as expected and torqued down without any drama.

Sebastian ★★★★☆

The black oxide finish on these is holding up well in my jig setup, no rust after a couple of weeks in a damp garage. Threads seated cleanly into pre-tapped holes without any binding, though the package count was a bit optimistic for what I needed.
