Product Description

PF31 and PF32 spring screws are fasteners that combine internal and external threads with a spring design, providing self-adjusting elasticity that automatically adjusts the tightening force in response to load changes, vibration, or temperature fluctuations. PF31 screws are primarily used for fastening connections in high-load, high-vibration environments and are widely used in machinery, automotive, and electrical equipment, especially suitable for applications requiring long-term stable connections, resistance to loosening, and vibration resistance.

Key Features

• Self-adjusting fastening force:The PF31 and PF32 spring screw features a built-in spring that automatically adjusts the tightening force according to load changes, ensuring the connection always maintains appropriate pressure. It is suitable for environments with large load variations or intense vibrations and can maintain a tight fit during prolonged use.
• Vibration and shock resistance:Due to its spring design, the PF31 spring screw absorbs vibration and shock, reducing the impact of external forces on the connection and maintaining connection stability. It also reduces the effect of vibration on the tightening force.
• High strength and durability:Made of high-strength alloy steel or stainless steel, PF32 screws can withstand significant tensile and compressive forces, ensuring long-term stable performance. Their durability makes them suitable for use in environments requiring sustained high loads.
