The partial threading on these screws made aligning them in tight spots so much easier than fully threaded bolts I've used before. They held up great under heavy load on my shop press without any sign of stripping.

The hex heads fit my socket perfectly, and the yellow zinc coating seems more durable than the usual black oxide finish. These grade 5 bolts cinched down a heavy equipment bracket without any stripping or hassle.

I needed some partially threaded bolts for a machinery repair, and these Grade 5 hex heads fit the bill perfectly. The threads are clean and they seated nicely with a socket wrench, no issues at all.
