Value Collection R57900625 Slotted Spring Pin 30mm Steel

Product Description

The VALUE COLLECTION R57900625 is a slotted spring pin manufactured from 1070-1080 grade steel with a plain finish. Slotted spring pins, also called roll pins, are hollow cylindrical fasteners with a longitudinal slot that allows radial compression during installation. This compression creates a spring-loaded interference fit inside a drilled hole, locking the pin in place without adhesives or secondary fasteners. At 30 mm long and 3.50 mm in diameter, this metric pin suits precision mechanical assemblies where controlled retention force and vibration resistance are required. Machinists, millwrights, and maintenance technicians install these pins in shafts, hinges, linkages, and machine frames across industrial and OEM applications.

This slotted spring pin is suited for metric mechanical assemblies in industrial machinery, automotive components, agricultural equipment, and general manufacturing fixtures. The plain finish makes it appropriate for interior or protected applications where corrosion exposure is limited. Its metric dimensions conform to standard ISO hole tolerances, making it a drop-in fit for any drilled hole sized to accept a 3.50 mm slotted spring pin. Maintenance and assembly technicians working to metric specifications will find this pin a direct fit for common shaft-to-component retention tasks.

Key Features

• Slotted design allows radial compression for a secure interference fit in drilled holes
• 1070-1080 grade steel construction provides high tensile strength and shear resistance
• 30 mm overall length suits a wide range of shaft and linkage retention applications
• 3.50 mm diameter conforms to standard metric hole tolerances
• Plain finish suitable for protected or interior mechanical environments
• Metric system of measurement for direct compatibility with ISO-dimensioned assemblies

Compatibility

Designed as a standard metric slotted spring pin for use in any drilled hole application requiring a 3.50 mm diameter, 30 mm long roll pin to ISO metric specifications.

Installation Notes

Slotted spring pins are driven into pre-drilled holes using a pin punch and hammer or a press. Always ensure the hole diameter matches the pin nominal diameter per manufacturer tolerances before driving. Align the slot toward the direction of applied load when orientation matters for shear applications. Wear appropriate eye protection during installation, as compressed pins can release energy if misaligned.
