Customer Reviews (4.6 / 5 · 5 reviews)

Michael ★★★★★

These shoulder screws fit perfectly into a custom jig I’m building, and the ground surface makes them spin smoothly as an axle. The black oxide finish looks clean and professional, and the hex drive gave good torque without stripping.

Emily ★★★★★

The hex drive is a nice touch—it let me really torque these down without stripping. Used a pair as a pivot axle for a jig and the precision ground shoulder spins true with zero wobble. Solid hardware.

Adam ★★★★★

These shoulder screws were exactly what I needed for a jig build where the pivot point had to be dead-on. The precision ground shoulder made for a smooth, wobble-free fit in the bearing I was using.
