Abigail O. ★★★★★

These shoulder screws came in handy for making a precise pivot point on a small jig I was building; the ground shoulder fit the bearing perfectly. Nice that they’re stainless steel too, so I don’t have to worry about rust in the shop.

Daniel O. ★★★★☆

Used one of these as a pivot point on a jig I built, and the socket drive held up perfectly even under heavy torque. The stainless finish seems like it'll resist rust well in my shop, though I wish they came with a few more threads for really thick applications.

Eli U. ★★★★☆

The precision-ground shoulder on these screws made installation as axle pins for a jig much smoother than I expected. Nice snug fit in the bearing bore, though the included hex key could be a bit longer for easier torque. Solid value for the pack of 25.
