غسالات قفل متوسطة مشقوقة 7/16 | فولاذ مؤكسد أسود (2000 / عبوة)

Installed these on a trailer hitch assembly and they held tight through a rough gravel road run. The black oxide finish feels durable and resists surface rust so far. Exactly what I needed for high-vibration applications.

I needed a bulk order for a project involving heavy machinery, and these held up perfectly under constant vibration. The 2000-count package is a solid value for the quantity.

Just finished a small engine project and these lock washers held everything tight through the first test run. The black oxide finish looks clean and didn’t flake off during installation. Nice to have a full box for future jobs.
