Customer Reviews (4.4 / 5 · 5 reviews)

Jacob S. ★★★★★

Noticed these have a nice smooth finish on the shoulder that makes them work perfectly as a bearing surface in my small assembly jig. The socket drive grips well enough to sink them flush without stripping.

Eva M. ★★★★★

The precision-ground shoulder on these screws made setting up a jig for repetitive drilling much more accurate than I expected. They fit perfectly as pivot points on my custom fixture.

Ella R. ★★★★★

The precision-ground shoulder on these screws made aligning the pivot on my jig perfectly smooth. They're exactly the right length for a 4-inch axle setup. Fast shipping and solid packaging.
