MS27183-15 | حلقات مسطحة عسكرية | فولاذ مطلي بالكادميوم (500 قطعة/عبوة)

Used these washers on a few bolts for a gate hinge repair, and the cadmium coating seems tough enough to resist rust. The load distribution is exactly what I needed under the fastener heads.

Picked up a pack of these for a structural project, and the cadmium finish is holding up perfectly against moisture so far. The consistent 0.375-inch inner diameter fits my bolts without any play.

The cadmium coating on these washers feels substantial and well-applied, so they should hold up better than standard zinc-plated ones in a damp environment. Packed 500 per order, they’re exactly what I needed for evenly distributing pressure under bolt heads.
