حلقات قفل داخلية مسننة 7/16 بوصة | فولاذ مطلي بالزنك (100 / عبوة)

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.

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.

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.
