غسالات قفل أسنان خارجية M6 | فولاذ مطلي بالزنك ثلاثي التكافؤ (1000/عبوة)

The trivalent zinc finish on these M6 washers looks clean and uniform, and they grip well under heavy vibration. I've used them on a few projects now and haven't had a single fastener loosen up. Solid value for a bulk pack.

Bought a thousand of these to rebuild a vibrating machine at work, and the trivalent zinc coating held up great through the whole install. No bent teeth or flaking, and they sit flat under the bolt head exactly as they should. For the price, this pack should last me years.

These M6 lock washers have a nice sharp tooth profile that really bites into the metal. Used them on a vibration-prone motor mount and nothing has budged since. The trivalent zinc finish looks clean and consistent across all 1,000 pieces.
