MS Big Body Flat Washer (Type A):(⅝") 17.0-17.4 x 38.0-39.0 x 2.2 /ZP

This MS Big Body Flat Washer (Type A) is constructed from mild steel and features a zinc-plated surface finish to provide a degree of corrosion resistance for general industrial use. The washer is designated for a nominal diameter of 5/8 inches, with an outer diameter range of 17.0 to 17.4 millimeters and an inner diameter range of 38.0 to 39.0 millimeters, along with a nominal length of 2.2 millimeters. Buyers typically select this big body style over standard flat washers when greater bearing surface area is required to distribute the load of a fastener more effectively across the material surface. The zinc plating offers a cost-effective protection layer suitable for indoor environments or applications with limited exposure to harsh weather. To ensure proper fitment, select this size based on the specific bolt head or nut dimensions and verify that the inner diameter accommodates the shaft while the outer diameter provides sufficient clamping pressure distribution.
