Daniel ★★★★★

The hex socket drive is spot on for getting into tight spots, and the cup point grips the shaft firmly without any slipping. I used these to lock a small collar in place and the black oxide finish made them easy to handle. Solid buy, came in a sturdy 100-pack that’ll last me a while.

Claire ★★★★★

I needed tiny set screws for a precision fixture and these #4-48 x 1/8" cup points fit the tapped holes perfectly. The thermal black oxide finish gives them a nice grip without being too slick.

Olivia Z. ★★★★☆

The hex socket drive seated perfectly on my driver without any wobble, and the thermal black oxide finish looks clean on the shaft. Only gripe is the 1/8" length feels a bit short if you're working with thicker hubs, but for precise locating it does the job.
