Eva ★★★★★

Zinc plating on these screws is holding up well so far without any rust, and having 2000 in a single package saves me from running to the hardware store mid-project. The slotted drive works fine with a standard screwdriver, and the hex head gives good grip when I need extra torque.

Ryan U. ★★★★★

The hex head on these screws gives a nice, secure grip with a standard screwdriver. I needed a bulk pack for attaching steel panels, and the zinc coating has held up well against minor rust so far. A solid, no-fuss choice for metal fastening jobs.

Matthew H. ★★★★★

I mounted several steel enclosures to a workbench with these screws, and the hex head gave me a solid bite with a wrench even in tight spots. The zinc plating seems consistent across all 2000 pieces, no burrs or stripped slots in the batch I used so far.
