Edward V. ★★★★★

The hex socket drive fits my T-handle perfectly, and the cup point holds securely without slipping. These are great for mounting brackets on a custom rig.

Evelyn ★★★★★

The black oxide finish on these cup point screws is holding up nicely with no wear after installing a dozen of them. The hex socket drive grabs firmly without slipping, which saved me from stripping the heads during assembly.

Penelope ★★★★★

I needed a set screw that wouldn’t strip out during installation, and these hex socket ones held up perfectly under torque. The black oxide coating looks nice and seems to resist rust so far.
