A4-80 Stainless Steel Square Washers , DIN436
A washer is a thin plate (usually disk-shaped) with a hole that is
most commonly used to distribute the load of a threaded fastener,
such as a screw or nut. Washers are most typically made of brass, nylon, steel, stainless
steel, thermoplastic, or rubber, and come in a wide variety of
styles and sizes.
Designed to limit stress on contacting parts, square washers are
useful for reducing noise, vibration and electrical current.
Required in many building codes, square plate washers are more
effective in creating a good friction connection between the sill
plate and the anchor bolt.
