There are many ways to call a non loosening screw, such as a spring screw or a hand screw. The non loosening screw can be riveted to an iron plate and can be freely screwed in and out, and the whole piece can be firmly embedded in the panel without detaching from it, so it is also called a non loosening screw.
Loosening screws are used to firmly connect the flower teeth on the rivet sleeve to the sheet metal through riveting, and then use the elasticity of the spring to tighten or loosen the connection by hand. The screws will not fall off and are used in places where installation or disassembly is often required, which is very convenient. Loosening screws are high-tech products in fasteners. Due to the characteristics of loosening screws, they can improve work efficiency and facilitate use.
Loose screws are mainly used in the following industries:
1. Stainless steel plate, metal steel plate, galvanized steel plate, engineering installation.
2. Metal curtain walls, metal light partitions, and other indoor and outdoor installations.
3. General angle steel and channel steel. Iron plates are installed in combination with other metal materials.
4. Assembly projects for car carriages, container boxes, shipbuilding industry, refrigeration equipment, etc.
The reason why the screws cannot be loosened is because the product has a ring of embossed teeth on the head, which will not fall off when screwed in or out of the thread after riveting installation, occupying very little space and filling the installation error between the base fitting holes.
