Value Collection R57900877 Slotted Spring Pin 40mm 12mm Steel

Product Description

The VALUE COLLECTION R57900877 is a slotted spring pin designed for use in mechanical assemblies requiring a reliable, friction-fit fastener. This metric pin measures 40 mm in length and 12 mm in diameter, manufactured from 1070-1080 grade carbon steel with a plain finish. The slotted design allows the pin to compress during installation and expand against the bore wall, providing secure retention without adhesives or secondary fasteners. Machinists, millwrights, and mechanical assembly technicians install this type of pin in shafts, linkages, and precision-fit housings across a wide range of industrial and OEM applications.

This slotted spring pin is suited for metric assembly work in manufacturing, maintenance, and repair environments. The 1070-1080 carbon steel construction provides good shear strength and durability in moderate-load applications. Plain finish makes the pin compatible with most assembly environments where corrosion exposure is not a primary concern. It is commonly installed in shaft-to-hub connections, clevis assemblies, and pivot points in mechanical equipment.

Key Features

• Slotted design compresses on installation for secure interference fit in the bore
• 40 mm overall length in metric sizing
• 12 mm diameter for medium-duty shaft and linkage applications
• 1070-1080 grade carbon steel construction for reliable shear strength
• Plain finish suitable for standard indoor and controlled industrial environments
• Does not meet military specifications — suitable for commercial and industrial use

Compatibility

Designed as a standard metric slotted spring pin for use in mechanical assemblies requiring a 12 mm diameter, 40 mm length interference-fit fastener in commercial and industrial equipment.

Installation Notes

Slotted spring pins are typically installed by millwrights or mechanical technicians using a pin punch and hammer or an arbor press. Ensure the receiving bore diameter matches the nominal pin diameter to achieve the correct interference fit. De-energize and lock out all equipment before installation or removal per applicable OSHA lockout-tagout procedures. Do not reuse a spring pin that has been fully compressed or shows visible deformation.
