Product Description

PF21 and PF22 spring screws are fasteners that combine a threaded design with a spring. Their built-in spring design allows them to automatically adjust the tightening force in response to load changes, vibration, and temperature fluctuations, ensuring sufficient pressure at the connection and preventing loosening due to environmental changes. PF21 spring screws are particularly suitable for applications requiring anti-loosening, vibration resistance, and high-strength connections, and are widely used in machinery, automotive, electrical, and electronic equipment industries.

Key Features

• Self-adjusting fastening force:The PF21 and PF22 spring screw features a spring design that automatically adjusts the tightening force according to external pressure or load, ensuring a consistently stable connection. It is particularly suitable for working environments with fluctuating loads or significant temperature variations.
• Anti-loosening function:The spring design enhances the screw's anti-loosening performance, making it particularly suitable for high-vibration environments such as machinery and automobiles. It effectively prevents screws from loosening due to vibration or impact, maintaining a secure connection.
• Vibration and shock resistance:The spring structure design effectively absorbs vibration and impact forces, reducing the impact of external impacts on the connection parts and enhancing the stability of the connection. It is particularly suitable for applications requiring resistance to vibration and impact, such as automotive engines and aerospace equipment.
