حلقات قفل منشقة متوسطة M8 | فولاذ مطلي بالزنك (600 / عبوة)

Vibration is my biggest enemy in the workshop, but these washers finally stopped my mower deck bolts from backing out. The zinc plating looks clean and hasn't rusted in the damp garage yet.

Just put together a workbench with these and the vibration from my jigsaw hasn't loosened a single bolt yet—the zinc coating also held up well against a few drops of oil.

The zinc plating is doing its job—no rust after a week of outdoor assembly, and the split actually bites into the bolt threads. Six hundred in the pack means I won't run out halfway through the project, which is exactly what I needed.
