Grade 316 Stainless Steel Round Flat Washers offer superior corrosion resistance in Salt Water/Marine environments and when exposed to Chlorines, making Type 316 Stainless Steel fasteners the choice for severe industrial applications. Flat Washers are used to increase the bearing load surface and distribute the clamp load of the fastened connection.
The inside diameter of a washer will be slightly larger than its listed size for easy assembly with the matching bolt or screw.
316 Stainless Steel is a highly corrosion resistant Marine and Industrial grade non-magnetic austenitic alloy which differs from the more common 18-8 series of Stainless alloys by virtue of its higher molybdenum content (2-3%) and a higher nickel content (10-14%).
