The Self-Locking Washer is used in connection with lacing anchors and weld pins to fasten insulation blankets or covers in place. Just press the self-locking washer onto the pin up to the insulation materials until the desired position is reached. Then clip off, (or bend over) the remaining portion of the pin for a permanent attachment.

Both Round or Square self locking washers are available as a matter of design or application preference. The domed, multi-lanced hole design provides for ease of locating washers on pin and positive locking. Most styles of washers are manufactured with a beveled edge to prevent the washer from cutting into the insulation facing.
