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 washers on pin and positive locking. Most styles of washers are manufacturered with a beveled edge to prevent the washer from cutting into the insulation facing.
