Self Locking Square Washers

Production Fastening Systems Self-Locking Washers are used in conjunction with Production Fastening Systems 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 or
pin for a permanent attachment.

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

Production Fastening Systems Self-Locking Washers are available according to the chart above 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.
