Value Collection R57900883 Slotted Spring Pin 55mm 12mm Steel

Product Description

The VALUE COLLECTION R57900883 is a slotted spring pin engineered for reliable fastening in mechanical assemblies. This metric pin measures 55 mm in length and 12 mm in diameter, manufactured from 1070-1080 grade steel with a plain finish. Slotted spring pins use a longitudinal slot to allow radial compression during installation, creating a secure interference fit within a drilled hole. The 1070-1080 steel construction provides strong tensile characteristics suited to moderate-to-heavy shear and vibration loads. Licensed machinists, maintenance mechanics, and industrial technicians commonly install these pins in production and repair environments.

This pin is used in mechanical assemblies requiring a removable or permanent locating fastener in metric-dimensioned components. Typical applications include shaft-to-hub connections, linkage assemblies, gear and pulley retention, and general machine component alignment. The 12 mm diameter and 55 mm length position it for medium-to-large frame machinery, agricultural equipment, and industrial fabrication. Installation does not require threading and is compatible with standard drilled metric holes at the nominal diameter.

Key Features

• 55 mm overall length for medium-to-large frame mechanical assemblies
• 12 mm diameter provides a robust interference fit in nominal metric bores
• 1070-1080 steel grade delivers strong shear resistance and durability
• Slotted design allows radial compression for tool-driven or press installation and removal
• Plain finish suitable for dry or lubricated installation environments
• Metric dimensioning for direct fit in metric-specified hole patterns

Compatibility

Designed as an OEM-style replacement or standard metric slotted spring pin for mechanical assemblies requiring a 12 mm diameter nominal bore with 55 mm pin length per metric fastener standards.

Installation Notes

Installation is typically performed by a licensed machinist or maintenance mechanic using a pin punch and hammer or an arbor press. Always power down and de-energize the associated machinery before installing or removing spring pins. Drive the pin flush or to the specified depth using a punch sized to the pin diameter to avoid deforming the slot. Use appropriate eye protection and follow facility-specific lockout and tagout procedures during service.
