Customer Reviews (4.6 / 5 · 5 reviews)

Avery F. ★★★★★

Picked up these bolts for a heavy equipment repair and the hex head made torquing them down easy with a socket wrench. The yellow zinc coating looks consistent across all 150 pieces, no rust or defects in the batch.

Natalie ★★★★★

The partial threads on these grabbed perfectly when I bolted down a motor mount — no slipping or cross-threading, even with a socket on the hex head. The yellow zinc finish is holding up well against the shop grime. Solid pack for the price.

Ava ★★★★★

Installed these on a punch press at work and the partially threaded shaft made alignment much easier than fully threaded bolts. The yellow zinc coating looks good and seems to resist rust so far.
