Kevin ★★★★★

The yellow zinc finish on these Grade 5 bolts looks sharp and hasn't shown a speck of rust after a few weeks on my shop press. The partial threading made seating them in the frame a breeze, and the hex heads grabbed a socket perfectly. Solid value for a hundred pieces.

Chloe S. ★★★★★

The threading ran cleanly into my tractor's hitch mount without any binding, and the yellow zinc coating looks like it'll hold up well to our damp shop air. I used a socket to drive them and the hex heads grabbed perfectly.

James ★★★★★

I needed a solid bolt for a heavy equipment repair, and these Grade 5 hex heads held up perfectly under the torque. The zinc coating is a nice touch, no rust after a week of outdoor use.
