Value Collection R57700863 Coiled Spring Pin

Product Description

The VALUE COLLECTION R57700863 is a coiled spring pin designed for use in mechanical assemblies requiring a reliable, resilient fastening element. Manufactured from 1070-1090 alloy steel with a plain finish, this pin measures 0.1875 inches in diameter and 1.25 inches in overall length. Coiled spring pins are slotted along their length and compress during installation, then exert outward radial force against the host bore to lock in place. Machinists, millwrights, and maintenance technicians install these pins in production equipment, tooling fixtures, hinges, and general mechanical assemblies where vibration resistance and reusability are priorities.

This coiled spring pin is suited for general industrial and mechanical applications where inch-system fasteners are specified. It is appropriate for use in light to heavy equipment assembly, conveyor components, pivot points, and shaft-to-hub connections. The 1070-1090 alloy steel construction provides the toughness and fatigue resistance expected in dynamic load environments. This pin does not meet military specifications and is intended for standard commercial and industrial use cases.

Key Features

• Coiled spring design provides radial retention force without adhesives or secondary locking hardware
• 1070-1090 alloy steel construction delivers toughness and fatigue resistance in dynamic applications
• 0.1875 inch diameter and 1.25 inch length suit a wide range of standard bore sizes
• Plain finish — no coating — suitable for applications where surface treatments are applied post-installation or are not required
• Inch-system dimensioning for straightforward integration into US-standard mechanical designs

Compatibility

Designed as a standard commercial coiled spring pin for general-purpose inch-system mechanical assemblies. No specific equipment model compatibility is stated in the product data.

Installation Notes

Coiled spring pins are typically installed by machinists or maintenance technicians using a pin punch and hammer or a pneumatic press. The receiving bore should be sized per the applicable tolerance standard for coiled pins to ensure proper interference fit. Inspect the bore for burrs or debris before installation to avoid damage to the pin or housing. Follow applicable OSHA lockout/tagout procedures and de-energize or mechanically isolate equipment before servicing any assembly containing this pin.
