Customer Reviews (4.8 / 5 · 5 reviews)

Penelope ★★★★★

These are beefy screws, and the black oxide finish looks proper, not cheap. I used them to hold a heavy steel fixture plate and the threading cut clean with no binding.

Julian U. ★★★★★

Finally got these in for a big jig rebuild and the hex socket drive made torquing them down into tight spots a breeze. The 13-inch length was exactly what I needed to reach through multiple plates.

Madison ★★★★★

The black oxide finish on these 1-1/8-7 screws looks flawless and held up perfectly during assembly, no chips or scratches even after tightening with a hex key. The partially threaded design gave me exactly the grip I needed for a heavy machinery mount.
