حلقات مسطحة M4 | فولاذ مطلي بالزنك ثلاثي التكافؤ (2000/عبوة)

The trivalent zinc coating looks uniform across all 2000 pieces, and they seat flat against the surface without any wobble when torqued down. Sorting through a few at random, I didn't find a single burred edge or misshapen hole.

The trivalent zinc finish handled the dampness in my basement workshop without any rust, and each washer in this bulk pack has that solid, even shape you want under a bolt head. I've already used a few hundred on my garage shelf project and they've held up perfectly so far.

Installed these under M4 screws for shelving brackets and the zinc coating handles key scratches without bare metal showing. The 2000 count bag will outlast my small projects for sure.
