غسالات مسطحة SAE رقم 4 | فولاذ مقاوم للصدأ 316 (100 / عبوة)

Installed these under stainless screws on a boat railing, and the 316 grade gives me total confidence against saltwater corrosion. They sit flush against the surface without any play.

The 100-pack gives me enough to finish several projects, and the #4 size is perfect for my small fasteners. The stainless steel surface is smooth and burr-free right out of the bag.

The 316 stainless steel is exactly what I wanted for corrosion resistance, and the packaging was a neat, organized 100-count. They fit my #4 screws perfectly and the surface finish is smooth with no burrs to snag on.
