Customer Reviews (5.0 / 5 · 5 reviews)

Victoria ★★★★★

The threads run clean all the way down, which made tightening these into a steel bracket effortless without any binding. I’ve already used half the pack for a trailer repair and they’re holding up great in the weather.

Ella ★★★★★

Finally found a bolt where the head doesn't strip under moderate torque—these held firm while I was tightening into an aluminum bracket. Threads ran smoothly through a pre-tapped hole without binding.

Lily E. ★★★★★

These 18/8 stainless bolts arrived clean and ready to use. I used them to secure metal brackets to a wooden frame and the full threading gripped perfectly. They look like they'll resist rust well for outdoor use.
