Value Collection R57900537 Slotted Spring Pin 8mm

Product Description

The VALUE COLLECTION R57900537 is a slotted spring pin engineered for secure fastening in metric assemblies. This pin is 8 mm long with a 2.5 mm diameter and is manufactured from 1070-1080 grade steel with a plain finish. Slotted spring pins compress radially on insertion, creating a spring-loaded fit within a drilled hole. The result is a self-retaining fastener that resists vibration-induced loosening without the need for adhesives or secondary locking hardware. This type of pin is commonly installed by machinists, millwrights, and mechanical assemblers working in manufacturing, maintenance, and repair environments.

This slotted spring pin is suited for metric applications where a compact, high-retention fastener is required. Typical use cases include shaft-to-hub retention, gear and sprocket alignment, hinge pinning, and general mechanical assembly. The metric sizing makes it appropriate for equipment built to ISO or DIN standards. The plain finish is standard for interior or protected installations where corrosion exposure is minimal. This pin does not meet military specifications.

Key Features

• 8 mm overall length in a compact metric form factor
• 2.5 mm diameter for precise fitment in standard metric drilled holes
• 1070-1080 grade steel construction provides adequate spring force and shear strength
• Plain finish suited for non-corrosive interior assembly environments
• Slotted design allows radial compression for tool-driven or press installation
• Self-retaining fit resists vibration loosening without secondary fasteners

Compatibility

Designed as an OEM-style replacement or standard-stock slotted spring pin for metric mechanical assemblies requiring an 8 mm long, 2.5 mm diameter pin in 1070-1080 steel.

Installation Notes

Slotted spring pins are typically installed by machinists or mechanical assemblers using a pin punch and hammer or an arbor press. The receiving hole should be drilled to the appropriate metric tolerance for the pin diameter before installation. Ensure the assembly is de-energized and secured before driving the pin. Avoid reusing a spring pin that has been fully removed, as repeated compression cycles can reduce retention force.
