Value Collection R57900615 Slotted Spring Pin 20mm

Product Description

The VALUE COLLECTION R57900615 is a slotted spring pin designed for fastening and alignment applications in mechanical assemblies. This metric pin measures 20 mm in length and 3.50 mm in diameter, manufactured from 1070-1080 grade steel with a plain finish. Slotted spring pins compress radially during installation, creating a tight, vibration-resistant fit in drilled holes without requiring threaded fasteners. They are commonly installed by machine technicians, maintenance mechanics, and industrial assembly professionals across light and heavy manufacturing environments.

This pin suits metric fastening applications where a removable yet secure connection is needed between components such as shafts, levers, collars, and linkages. The 1070-1080 steel construction provides adequate shear strength and resilience for moderate-load mechanical assemblies. Its plain finish makes it appropriate for indoor or protected mechanical environments. Sold individually, with a minimum order quantity of 100 units, this pin is suited for production and maintenance procurement.

Key Features

• Slotted design allows radial compression for a secure interference fit in drilled holes
• 20 mm overall length in metric sizing for standard metric assemblies
• 3.50 mm diameter for common metric bore applications
• 1070-1080 steel construction provides reliable shear and fatigue resistance
• Plain finish suitable for protected indoor mechanical environments
• Does not meet military specifications — intended for commercial and industrial use

Compatibility

Designed as a standard metric slotted spring pin for use in commercial and industrial mechanical assemblies requiring a 3.50 mm nominal bore diameter and 20 mm pin length.

Installation Notes

Slotted spring pins are installed by mechanical technicians using a pin driver or punch and hammer. The receiving hole should be drilled to the nominal pin diameter to achieve proper interference fit. Ensure the assembly is depowered and secured before pin installation or removal. Use appropriate eye protection when driving pins to prevent injury from flying debris.
