غسالات قفل داخلية #10 | فولاذ مطلي بالزنك (5000 / عبوة)

These lock washers fit my #10 screws perfectly and the zinc coating looks consistent across the whole batch. I've used about a hundred so far and they hold tight even on my shop equipment that vibrates constantly.

I needed a bulk supply for a project with a lot of vibration and these steel washers with the zinc coating seem to be holding up perfectly. They fit snugly on the #10 fasteners without any wobble, and the box of 5,000 should last me years.

Picked up a box of 5,000 of these #10 internal tooth lock washers for a big project, and the steel zinc plated finish seems very well done for the price. They fit perfectly on the bolts and I’m confident they’ll prevent loosening from vibration as intended.
