Metric Oversized Washer
Metric oversized washers are round discs with a center hole and a large outside diameter, that is approximately three times the selected size. The oversized outer diameter provides a smooth surface when used in conjunction with a hex head bolt or hex nu and helps to spread clamping load. These metric flat washers are commonly used when soft or thin materials are utilized.
