The precision ground shoulder on these screws made for a perfect fit in my small engine repair project, spinning smoothly as a bearing surface. They drove in cleanly with a hex key and the black oxide finish looks durable. Exactly what I needed for a reliable pivot point.

These replaced a worn-out pivot in a piece of shop equipment, and the hex socket drive made installation a breeze. The black oxide finish seems durable and should hold up well against rust.

The ground shoulder on these is dead-on for precision work, so my fixturing runs true without any wobble. The black oxide finish also gives them a nice grip and protection that I wasn't expecting at this price.
