Customer Reviews (4.6 / 5 · 5 reviews)

Zoe P. ★★★★★

I needed a precision pivot for a jig I’m building, and the ground shoulder on these is dead-on consistent across all 25 pieces. The black oxide finish also gives them a nice, uniform grip without any galling when I torqued them down.

Amelia ★★★★★

The hex drive fit my torque wrench perfectly, and the black oxide finish hasn't shown any wear after a dozen uses. These screws made for a solid pivot point on my jig, exactly what I needed.

Charlotte ★★★★★

Used them as pivots for a custom jig and the precision ground shoulder makes them spin true without any wobble. The black oxide finish held up fine against the shop grime too. These will be my go-to for anything that needs a smooth, repeatable axle.
