Good for trailers
Super high-quality, clean threads, no superfluous metal chips in the container, nuts threaded right on these. I through bolted my trailer boards.

Decent bolts… but damaged box
I needed some bolts and ordered these. The bolts are OK, but what should have been a reusable storage container that they came in was damaged beyond repair in shipping and the bolts were loose in the shipping envelope.

Bolts seem OK.
What can I say? They were the right size, no threading issues, and haven't broken yet. It seems a little harder to find fully threaded bolts at hardware stores nowadays, so I'm glad I found them here.

Hard to find locally in this size fully threaded. This was exactly what I needed for elevating a cap to our patio heater that was being torn apart by high winds. These allowed me to replace the old shorter supports with these and beef up the cap with solid steel plates. Worked like a charm.
