Adam ★★★★★

Finally a pack of these small fasteners where each nut actually has cleanly cut threads. The zinc coating is even and consistent across all 5000 pieces in the box—no duds or rough edges to fight with.

Evelyn ★★★★★

Been hunting for a reliable source of these tiny #3-56 hex nuts for a while now, and this 5000-pack is a solid buy. The steel feels sturdy and the zinc plating is even, so they thread on smoothly without any binding. Glad I stocked up.

Jason R. ★★★★★

The zinc plating on these #3-56 nuts looks evenly applied and hasn’t flaked off even after I tightened a few with pliers. A full 5000-count bag means I’ve got plenty left over for future panel work, which is exactly what I needed.
