Value Collection R57700825 Coiled Spring Pin 3/16 in

Product Description

The VALUE COLLECTION R57700825 is a coiled spring pin engineered for secure fastening in mechanical assemblies where controlled radial force and vibration resistance are required. The pin measures 0.1875 inches in diameter and 2 inches in length, manufactured from 1070-1090 alloy steel with a plain finish. Coiled spring pins compress upon installation to apply consistent outward pressure against the bore wall, locking the pin in place without adhesives or secondary fasteners. This design makes them well suited for high-cycle applications subject to shock or dynamic loading. Installation is performed by machinists, millwrights, and maintenance technicians working across a broad range of industrial and mechanical equipment.

This coiled spring pin is appropriate for use in general mechanical assemblies, machine components, hinges, linkages, and drive train connections in both light and heavy industrial settings. The 1070-1090 alloy steel construction provides adequate tensile strength and spring-back for standard inch-series bore applications. The plain finish is suitable for indoor or protected environments where corrosion exposure is limited. This pin does not meet military specifications and is intended for commercial-grade applications.

Key Features

• Coiled design applies radial pressure against bore wall for a secure, self-retaining fit
• 0.1875 inch (3/16 inch) nominal diameter in standard inch-series sizing
• 2 inch overall length for deeper bore or through-pin applications
• 1070-1090 alloy steel construction provides strength and spring-back for dynamic load conditions
• Plain finish for use in protected or indoor environments
• Commercial-grade specification, does not meet military specifications

Compatibility

Designed as a standard inch-series coiled spring pin for general-purpose commercial mechanical assemblies using 0.1875 inch nominal bore diameter fastener locations.

Installation Notes

Coiled spring pins are installed by machinists or maintenance technicians using a pin punch and hammer or a press tool sized for the pin diameter. Always ensure the receiving bore is clean and free of burrs before driving the pin. Do not reuse a coiled spring pin that has been removed, as repeated installation cycles reduce the radial clamping force. Follow applicable machinery safety lockout-tagout procedures before servicing any assembly containing these fasteners.
