Self-Locking Washers - Square

After weld pins are welded in place and insulation is impaled over the weld pins, the Self Locking Washers are installed onto the weld pins to retain the insulation.

Self-Locking Washers are used in conjunction with weld pins, insul-anchors and lacing anchors to fasten insulation in place. Simply press the self-locking washer onto the pin up against the insulation until the desired position is reached and then clip off, or bend over, the remaining portion of pin for a permanent attachment.

The choice between Round or Square self-locking washers is basically a matter of aesthetics or personal preference. The domed, multi-lanced hole design provides for ease of locating washer on pin and positive self-locking. Some styles of washers are manufactured with a beveled edge to prevent the washer from cutting into the insulation facing.

Sunbelt Stud Welding Self-Locking Washers are available according to the chart below and with standard 10 GA, 12 GA, or 14 GA hole sizes off-the-shelf. Other material/plating combinations and hole sizes are available by special order.
