Brian A. ★★★★★

Had to replace a worn axle on a small conveyor roller, and these shouldered screws fit like a glove — the precision ground surface made alignment effortless. Definitely worth the price for the quality you get.

Alexander R. ★★★★★

Installed these as pivot pins in a jig I'm building, and the hex drive made tightening them down a breeze without marring the shoulder. The thermal black oxide finish seems like it'll hold up well to repeated adjustments in my shop.

Sophia Z. ★★★★★

The precision ground shoulder is dead on for using as a bearing surface, and the hex socket drive made installation a breeze. These are solid little workhorses, definitely worth the money for a pivot replacement job.
