Customer Reviews (4.6 / 5 · 5 reviews)

Alexander E. ★★★★★

The shoulder is machined dead-on straight, so my homemade hinge spins without any wobble. Took a bit of torque to drive them in, but the hex socket held up fine and the stainless finish looks clean against the aluminum.

Harper R. ★★★★★

The precision-ground shoulder on these screws made setting up a micro-adjustable hinge on my light fixture incredibly smooth. They fit perfectly and the stainless steel feels really robust for the price.

Harper ★★★★★

I needed a reliable pivot for a custom jig and these shoulder screws fit perfectly—the precision-ground shoulder made the alignment much smoother than using standard bolts. The stainless steel finish feels solid and corrosion-resistant, too.
