Daniel G. ★★★★★

Picked up a pack for some custom tooling fixtures and the hex drive seated perfectly without stripping. The zinc coating looks consistent across all 140 pieces, which saves time sorting through rejects.

Stella ★★★★★

I needed a solid batch for a jig build and these M4 x 20mm alloy steel screws are consistently well-threaded, with the zinc plating holding up fine after a few days in a slightly damp shop. The 140 count means I'll have plenty for the next few projects too.

Scarlett J. ★★★★★

The hex socket drive grips my allen key perfectly, no stripping even when I torqued them down on a jig. Came in a tidy 140-count pack, and the zinc finish looks uniform across every single screw.
