Customer Reviews (4.8 / 5 · 5 reviews)

Amelia C. ★★★★★

These hex bolts fit perfectly into my tractor’s mower deck mount, and the yellow zinc finish looks clean and corrosion-resistant so far. The partial threading made alignment easier during assembly.

Christopher Y. ★★★★★

Needed some Grade 5 hardware for a jig I’m building, and these hex heads fit a socket perfectly. The yellow zinc finish looks consistent across all fifty pieces, no duds in the bag. Good solid fasteners for the price.

Grace ★★★★★

The partial threading is exactly what I needed for a custom jig build—the unthreaded shank seats perfectly without binding. All fifty heads were clean and uniform, and they drove in smoothly with a socket.
