Square Self-Locking Washer
Introduction
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.

Characteristic
1, butt joint: the stress concentration is relatively small, carrying capacity is better.
2, corner joint: low bearing capacity, generally not used alone, mostly used for the corner of the closed structure.
3, lap joint: uneven stress distribution, low bearing capacity, simple preparation and equipment.
Application
The Square Washers have various applications in different industries.
Electrical installations: square washers are used to provide insulation between electrical components such as grounding devices, bolts, and wires. They prevent direct contact between conducting materials, reducing the risk of electrical short circuits and ensuring safety.
Construction and engineering: square washers are commonly used in construction and engineering projects where electrical or thermal insulation is required. They are often used in HVAC systems, plumbing installations, and other applications to prevent heat loss or transfer between components.
Appliance manufacturing: square washers are used in the manufacturing of various appliances such as refrigerators, washing machines, and electric ovens. These washers provide electrical insulation between different parts, reduce heat transfer, and contribute to the overall safety and efficiency of the appliances.
Automotive industry: In the automotive industry, the square washers provide insulation and vibration damping in engine assemblies, electrical connections, and suspension systems, among other applications.
Aerospace and aviation: square washers are important in aerospace and aviation applications because it will prevent the electrical interference and damage caused by extreme temperatures and vibrations. They are used in engine components, avionics systems, and electrical circuits to ensure reliable performance and safety.
