Zoe L. ★★★★★

I needed a bulk box of fully threaded 1/4-20s for a jig build and these Grade 8s threaded cleanly into tapped holes without any binding. The 1-1/8" length is just right for clamping two pieces of 1/4" plate without bottoming out.

Thomas P. ★★★★★

The yellow zinc finish on these Grade 8 bolts is holding up perfectly in a slightly damp shop environment, no rust after a month. Threads cut clean and the hex heads don't strip under moderate torque.

Evelyn ★★★★★

Bought these for a clamping fixture and the yellow zinc finish is holding up way better than the plain steel bolts I usually grab. The threads are clean and the hex heads seated perfectly in my socket, no stripping issues on the first dozen or so.
