Product Specification

38 mm Metal Insulation Speed Clips Square Type Insulation Pin Fixing Washers Self Locking Washer

Product Description

Metal insulation nails are a key accessory widely used in building insulation systems, mainly used to fix external wall insulation materials (such as rock wool board, extruded polystyrene board, polystyrene board, etc.), ensuring a strong bond with the base wall, while reducing thermal bridging effects and improving overall insulation performance. With the continuous improvement of energy-saving requirements in buildings, metal insulation nails have gradually replaced traditional plastic nails due to their durability, tensile strength, and fire resistance, becoming an important choice in modern building insulation engineering.

Operation Process

The working principle of self-locking washers can be simply summarized as "frictional resistance". When the threaded connection is subjected to external force, the self-locking washer will generate a reverse frictional force to prevent the thread from loosening. This friction force is determined by the special structure and material of the self-locking washer.

The structure of self-locking washers is usually composed of a metal ring and a layer of elastic material. Metal rings are usually made of stainless steel or copper, and their surfaces have some protruding tooth like structures. These tooth shaped structures can increase the friction between self-locking washers and threaded connections. Elastic materials are usually made of rubber or plastic, and their function is to increase the elasticity of self-locking washers, making them easier to fit tightly with threaded connections.

When the self-locking washer is installed at the threaded connection, its metal ring will generate friction with the threaded surface. This friction can prevent thread loosening. At the same time, the elastic material will also increase the elasticity of the self-locking washer, making it easier to tightly fit with the threaded connection. In this way, the self-locking washer can play a good role in preventing loosening.
