FLAT WASHER 11.1MM 7/16 BS3410 A2

A flat washer is a smooth, flat disc with a central hole, used to distribute the load of a nut or bolt over a larger surface area. It helps prevent damage to the material being fastened, reduces surface indentation, and provides a stable, even bearing surface. Flat washers are also commonly used to minimise loosening caused by vibration when paired with other locking components.
