Christopher ★★★★★

I needed a bolt that could handle serious torque without stripping, and these partially threaded alloy steel screws with thermal black oxide fit the bill perfectly. The flat head hex socket drive seated firmly, and the 6-inch length gave me just the right reach for my jig assembly.

Daniel O. ★★★★★

The hex socket drive seated perfectly on my allen wrench with zero wobble, and the thermal black oxide coating looks sharp against the steel. Threaded portion ran smooth into my jig setup without binding—these are exactly what I needed for a heavy machinery repair.

Penelope Q. ★★★★★

The black oxide finish on these 1 1/4-7 x 6" screws looks clean and resists scratching during assembly. The hex socket drive engages perfectly with my wrenches, and the partial threading holds tight in jig fixtures without slipping. Definitely solid for heavy-duty tooling work.
