Customer Reviews (4.8 / 5 · 5 reviews)

Olivia ★★★★★

The hex heads on these screws grabbed my socket perfectly without any slipping, and the yellow zinc coating looks great. I used them to secure a heavy motor mount on my lathe, and they held firm through the first test run. It's reassuring to have these USA-made fasteners behind a critical load.

Natalie ★★★★★

Needed some high-strength bolts for a press repair, and these 1/2-13 x 5-1/2" hex heads were exactly what the job called for. The yellow zinc finish looks like it will resist corrosion well, and the threads were clean and consistent right out of the package.

Timothy ★★★★★

Used them to rebuild the mounting bracket on a punch press and the yellow zinc finish made them easy to spot during the teardown. Threads cut clean and the hex heads seated perfectly with a socket wrench, no rounded corners. Solid domestic hardware that I’ll be ordering again.
