Customer Reviews (5.0 / 5 · 5 reviews)

Ruby R. ★★★★★

I needed a bulk pack of these for a shop project and the hex heads fit my socket perfectly without any stripping. The yellow zinc coating looks uniform across all 2,500 pieces, which gives me confidence they’ll hold up in my assembly work.

Sofia ★★★★★

The threads are clean and consistent across every single screw, which saved me time on the assembly line. These grade 8 fasteners feel solid with the yellow zinc coating, and the full box of 2,500 is a great value for heavy use.

Michael ★★★★★

Was skeptical about buying a full box, but these hex heads fit my torque wrench socket perfectly and the Grade 8 steel really holds up under heavy clamping load.
