Customer Reviews (5.0 / 5 · 5 reviews)

Thomas ★★★★★

Needed some heavy-duty bolts for a press fixture at work and these 3/8-16s fit perfectly with the hex head letting me torque them down tight with a socket. The yellow zinc coating looks good and should hold up fine in the shop environment.

Robert ★★★★★

Used these to rebuild a trailer hitch mount and the threads were clean and consistent on every single bolt. The hex heads held up to the impact driver without stripping.

William R. ★★★★★

The yellow zinc finish held up perfectly through a greasy weekend of machinery work, and every one of the 50 threads seated cleanly without a single burr. These PFC9 alloy steel bolts are the real deal for heavy assembly.
