Customer Reviews (4.2 / 5 · 5 reviews)

Emily Z. ★★★★★

These are perfect for a job I just finished mounting a gear on a shaft. The hex socket drive made installation straightforward, and the black oxide finish looks clean and professional.

Leo S. ★★★★★

Used these to secure a pulley on a motor shaft — the cup point bites in just right. The black oxide finish seems durable and hasn't shown any rust yet after a few weeks in a damp shop.

William U. ★★★★☆

The cup point really bites into the shaft when I torqued these down, and the black oxide finish keeps them from rusting in my shop's humid air. Only gripe is the 100-count box is a lot to store if you only need a dozen, but the price per screw makes it worth it.
