Customer Reviews (4.4 / 5 · 5 reviews)

Grace W. ★★★★★

The partially threaded design made it easy to align these into tight spots on my press. The yellow zinc coating seems durable and the hex head seated perfectly with my socket. Exactly what I needed for the assembly job.

Stella Y. ★★★★★

The partially threaded shank on these Grade 5 bolts made mounting a hydraulic pump bracket a breeze, and the yellow zinc finish matches the rest of my hardware nicely.

Emily U. ★★★★★

Needed a bunch of these for a tractor hitch project, and the Grade 5 yellow zinc held up perfectly under a torque wrench. The partially threaded shank made alignment a breeze, and the whole lot was clean and consistent.
