Conical Spring Washer
A slightly dished washer that flattens as the joint is tightened, then keeps the bolt tight when the joint settles or the parts expand with heat. It is installed under the bolt head or nut and tightened with a standard wrench or socket. Typical uses include busbars, electrical terminals and joints that heat up and cool down.
