Product Description

PF41 and PF42 spring screws are high-performance fasteners that combine internal and external threads with a spring, designed for applications requiring elastic support, resistance to loosening, and vibration damping. The PF41, through its built-in spring structure, automatically adjusts pressure under varying loads, vibrations, and temperature fluctuations, ensuring the nut always maintains sufficient tightening force.

Key Features

• Self-regulating pressure:The spring function of PF41 and PF42 spring screws automatically adjusts the tightening force according to load changes, ensuring a secure connection and preventing loosening due to load variations or temperature fluctuations. This function is particularly suitable for working environments with temperature fluctuations, load variations, or long-term load-bearing conditions.
• Vibration and shock resistance:The elastic properties of the spring enable the PF41 screw to absorb external vibrations and shocks, reducing the impact of vibration on connection stability. It is particularly suitable for high-vibration, high-impact working environments, such as engines and mechanical equipment. Examples include automotive chassis and mechanical equipment.
• High strength and durability:PF41 and PF42 spring screws are made of high-quality alloy steel or stainless steel, have high strength, can withstand large loads, and maintain durability for a long time.
