حلقات فاصلة 1/4 × 1 | فولاذ مع أكسيد أسود (1000 / عبوة)

I needed a bulk option for a framing project and these washers came through—the black oxide coating looks uniform across all thousand pieces. They sit flat and distribute load nicely without any burrs or rough edges, which saves me time on the job.

Exactly 1000 count in the bag and the black oxide finish resists corrosion better than plain zinc on the truck frame I was fixing. Feels solid for spreading the load under those heavy carriage bolts.

Finally got around to installing these on a trailer fender repair, and the black oxide finish held up perfectly against the first rain. The 1000-count box is way more than I'll ever need, but the price per washer was too good to pass up.
