3/8 BELLEVILLE WASHER STAINLESS 316

Description

A 3/8″ Belleville washer made of 316 stainless steel is a cone-shaped metal disc used with a 3/8 inch bolt. Its bowl-like shape acts as a tough spring. It pushes back when squeezed to stop bolts from loosening. The 316 grade means it fights off rust and salt in tough outdoor areas.
