Customer Reviews (4.4 / 5 · 5 reviews)

James ★★★★★

Threads are clean and the hex socket seated perfectly on my driver—no wobble or stripped corners. Used them to bolt down a jig base and they held up through a full day of heavy cuts. The thermal black oxide looks solid, and the 250 count means I’m set for a while.

Timothy ★★★★★

Installed these in a jig for a production run and they seated perfectly without any binding. The black oxide finish on these USA-made alloy steel screws looks consistent across all 250 pieces.

Abigail E. ★★★★☆

The black oxide finish on these screws feels durable and hasn’t chipped during my jig assembly work. They fit my hex driver perfectly and the threads are clean. Only wish the package had a few extra for the price.
