Customer Reviews (4.8 / 5 · 5 reviews)

Timothy C. ★★★★★

Zinc plating looks uniformly applied, no rough edges or flakes right out of the bag, and all 200 threads are clean with no binding when I test-fit them with a nut. These will be perfect for mounting brackets on my shop equipment.

Julian Q. ★★★★★

I bought these for a workbench build and the zinc plating looks clean and consistent across all 200 pieces. The fully threaded shaft let me get solid engagement in some tight spots where partial threads would have failed.

John E. ★★★★★

The hex head on these M8 bolts gave my socket wrench a solid grip, and the zinc plating seems thick enough to resist rust in my shop. Finished a machinery stand build with the full 200-pack and didn’t have a single stripped thread.
