حلقات قفل خارجية بأسنان #6 | فولاذ مطلي بالزنك (2000 / عبوة)

Out of the box I noticed the zinc plating is smooth and even, so they sit flat against the surface. Used about 150 of these on a small vibration-prone assembly and they held everything tight. Exactly what I needed for the price.

Went through about 400 of these on a weekend project tightening brackets, and not a single one split or stripped. The zinc plating holds up well under a decent amount of moisture, and they bite into the bolt threads firmly. Good value for a bulk bag that'll last me years.

Exactly 2000 pieces in the bag, so I can finally replace all the worn-out lock washers on my workshop equipment. The zinc coating looks clean and consistent, and the teeth bite into the metal nicely.
