Richard ★★★★★

The zinc plating looks clean and uniform across all 200 pieces, and they bite into the bolt threads without any skipping. I’ve used a handful on a vibrating lawn mower deck and nothing has backed out after a few weeks of runs.

Emily ★★★★★

These #12 washers fit perfectly on the bolts for my lawn mower deck, and the zinc coating looks like it’ll resist rust well. The steel feels sturdy enough to hold up against the vibration from the engine.

Jacob N. ★★★★★

Just finished a small engine mount repair and these #12 washers held everything tight through a full weekend of rough riding. The zinc plating is evenly applied, no flaking or rough edges, and the external teeth really bite into the surface. Grabbed the 200-pack so I’m set for years of projects.
