Customer Reviews (4.8 / 5 · 5 reviews)

Chloe O. ★★★★★

The zinc plating on these hex bolts looks clean and even, and they threaded smoothly into my steel frame without any binding. They felt solid under the wrench, just what I needed for a heavy assembly job.

Chloe E. ★★★★★

Used these for mounting some heavy steel brackets and the Class 8.8 zinc plating held up perfectly against the wrench without any stripping. The fully threaded shaft gave a really solid grip, and all twenty screws had consistent, clean threads.

Isabella ★★★★★

The threading is perfectly clean, so these screws drove in without any binding. I used them to secure a steel bracket to a frame, and the zinc plating looks like it'll hold up fine.
