These shoulder screws fit perfectly into my jig's axle holes—the precision-ground shoulder makes a huge difference for smooth rotation. I've got them holding a heavy clamping mechanism and they haven't budged under load.

I’ve used these as precision pivot points in a custom jig, and the ground shoulder fits the bushing perfectly with zero wobble. The hex drive made installation straightforward, and the alloy steel feels solid enough for repeated use.

I needed a sturdy axle for a small mechanical project, and the precision-ground shoulder on these screws made for a smooth, wobble-free fit in the bearing. The hex drive was easy to torque down without stripping.
