Customer Reviews (4.4 / 5 · 5 reviews)

Natalie ★★★★★

The partially threaded shank made all the difference when I needed the grip length to align two steel plates—no slippage at all. Zinc coating looks clean and even across all 250, and the hex heads seated perfectly with a standard wrench. Packed well, zero bent threads on arrival.

Andrew H. ★★★★★

Opened the box and these bolts are exactly the right length for clamping down my new workbench top. The zinc plating looks consistent and clean, and the hex heads fit my wrench without any stripping.

Edward ★★★★★

The partially threaded shank on these bolts made alignment in my steel brackets much easier than fully threaded ones. All 250 pieces came with clean threads and a consistent zinc finish.
