Customer Reviews (4.6 / 5 · 5 reviews)

Harper ★★★★★

Put a set of these on a hydraulic cylinder rebuild and the Grade 8 steel felt reassuringly solid under the torque wrench. The yellow zinc held up perfectly during the test run with no visible wear.

Ellie T. ★★★★★

These bolts were exactly what I needed to reassemble a press. The hex heads let me get a socket on them easily, and the grade 8 yellow zinc finish looks tough.

David O. ★★★★★

Finally found a bulk pack of partially threaded 3/8-16 bolts that actually hold up under torque. The yellow zinc coating looks uniform across all 650 pieces. These grade 8s went straight into my equipment assembly without a single stripped thread.
