Customer Reviews (5.0 / 5 · 5 reviews)

Evelyn O. ★★★★★

Used these for a hydraulic pump mount where I needed the smooth shank to bear against the bracket, and the yellow zinc held up fine against the oil and grime. The tolerances were spot-on, so they threaded in smoothly without any binding.

Isabella Y. ★★★★★

The partially threaded shank on these Grade 5 bolts let me snug up a stubborn engine mount without fighting threads the whole way. The yellow zinc coating looks solid and didn't flake during tightening. A solid choice for heavier equipment repairs.

Violet Y. ★★★★★

The hex heads grabbed my socket wrench nicely without any slipping, and the yellow zinc coating looks clean and corrosion-resistant right out of the package. I used a handful to secure a heavy bracket, and the partially threaded design made alignment a breeze.
