Customer Reviews (4.0 / 5 · 5 reviews)

Carter ★★★★★

Perfect fit for my drill press jig—the black oxide finish matches the machine look nicely. The hex socket drive is a welcome detail for a clean, flush mount with a standard hex key.

Brian X. ★★★★☆

The nylon pellet inside these is a nice touch—it locks the threads without needing a separate washer. Used them on a fixture plate and they've held up fine, though one had a slightly burred edge out of the bag.

Violet G. ★★★★☆

Used these for mounting a router plate in my CNC table and the flat heads sit perfectly flush. The black oxide finish seems durable and hasn't scratched during installation.
