AN960KD416L 軍規平墊圈 | 鋼鍍鎘 (200個/包)

Used a handful of these on an outdoor bracket assembly, and the cadmium finish is holding up well against a light drizzle. They're a solid thickness, too, so no bending under moderate torque.

I needed some corrosion-resistant washers for a chassis ground point, and these steel cadmium ones fit perfectly under the bolt head. The 200-count pack gives me plenty for future projects, and each washer has a consistent thickness that distributes load evenly without distorting.

These washers have a nice tight tolerance, they sit perfectly flat under my bolts without any wobble. The cadmium finish feels slick and solid, and a pack this size will last me through several projects.
