Aurora I. ★★★★★

I needed a precision axle for a small machine build, and the ground shoulder on these screws slides perfectly into a bearing bore with zero wobble. The hex socket drive made installation clean and easy, even in a tight spot.

Leo ★★★★★

These screws have a really tight fit in my jig's pivot holes. The precision-ground shoulder makes them work perfectly as an axle for a small rotary table I'm building.

George ★★★★★

Used a couple of these as pivot points for a custom clamping jig, and the precision-ground shoulder made for zero wobble in the rotation. The stainless steel finish feels quality, and all 25 pieces had clean, uniform threads.
