غسالات قفل داخلية رقم 8 | فولاذ مطلي بالزنك (1900 / عبوة)

I needed these for a machinery repair and the zinc plating on all 1900 pieces was consistent with no flaking. They gripped the bolt threads firmly even when I tested them with a impact driver.

These washers bit perfectly into the bolt shank when I torqued them down, and the zinc plating seems really consistent across the whole batch. I used them on a vibrating table assembly and nothing has loosened up after a week of running.

Had a project with a lot of vibration concerns, and these #8 internal tooth lock washers held everything tight perfectly. The zinc plating looks good and the steel feels solid for the price.
