Metal - Copper Washers
A Copper washer is a small circular disc made from brass material. It is used in a variety of applications to provide a flat surface for distributing the load of a screw, bolt or nut. The washer's shape helps prevent the screw or bolt from sinking into the surface of the material being fastened, which can cause damage or looseness over time.
Copper washers are typically thin and have a central hole, which allows them to fit over the screw or bolt. They are commonly used in plumbing, automotive, and industrial applications, as well as in household repairs and DIY projects.
