MIDWEST FASTENERS Self-Locking Washers are used in conjunction with MIDWEST FASTENERS weld pins, insul-anchors and lacing anchors to fasten insulation in place. Simply pressthe self-locking washer onto the pin up to the insulation until the desired position
is reached. Then clip off, (or bend over) the remaining portion of 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 washer 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.
