Hazel ★★★★★

The yellow zinc coating is holding up well in my slightly damp workshop, and the hex heads grab perfectly with a 12-point socket. Exactly what I needed for reassembling a small engine.

Alexander X. ★★★★★

Used these to replace the stripped bolts on my press brake table, and the Grade 5 strength held up perfectly under load. The yellow zinc coating looks good and hasn't shown any rust after a few weeks in a humid shop.

David ★★★★★

I needed a batch of these for a jig I’m building, and the fully threaded design made tightening down on varying thicknesses a breeze. The hex heads catch the socket perfectly without stripping, and the zinc finish looks clean even after a few days in the garage.
