Alexander E. ★★★★★

Had a slight rattle in my lawn mower deck that I couldn't chase down, and these did the trick once I torqued them on. The internal teeth bite into the bolt head nicely, and the zinc plating kept them from rusting after a few rainy weeks. Pack of 100 means I've got plenty for future projects.

William K. ★★★★★

Installed these on my workbench vice mount and they’ve held rock solid through heavy twisting. The zinc plating looks clean and hasn’t shown any rust after a few weeks in a damp garage.

Alexander ★★★★★

These washers held my mower deck spindles tight after weeks of use, and the zinc coating hasn't shown any rust yet. Nice snug fit on the 7/16 bolts I needed them for.
