Value Collection R57700823 Coiled Spring Pin 3/16 in Alloy Steel

Product Description

The VALUE COLLECTION R57700823 is a coiled spring pin designed for use in mechanical assemblies requiring a secure, vibration-resistant fastening solution. With a nominal diameter of 0.1875 inches (3/16 inch) and an overall length of 1.75 inches, this pin is manufactured from 1070-1090 alloy steel with a plain finish. The coiled design allows the pin to compress during installation and expand outward against the bore wall, distributing stress evenly across the length of the pin. This construction makes it suitable for high-load and high-cycle applications where fatigue resistance matters. Maintenance technicians, millwrights, and assembly professionals install this type of fastener in shafts, linkages, and component retention applications.

This coiled spring pin is suited for general industrial and mechanical assembly use across a wide range of equipment types. Common install scenarios include shaft-to-hub connections, hinge pivots, clevis pins, and component alignment applications where a controlled press-fit retainer is required. The plain finish is appropriate for indoor or protected installations. This pin follows inch-system dimensions and is compatible with standard 3/16-inch bore applications. It does not meet military specification requirements and is intended for commercial-grade mechanical assemblies.

Key Features

• Nominal diameter of 0.1875 inches (3/16 inch) fits standard inch-series bores
• Overall length of 1.75 inches provides substantial engagement depth for secure retention
• 1070-1090 alloy steel construction offers high tensile strength for demanding mechanical environments
• Plain finish suits dry or protected installation environments
• UNSPSC Code 31163201 for procurement and catalog classification

Compatibility

Designed for use in standard 3/16-inch diameter bores in inch-system mechanical assemblies. No specific model or system compatibility data was provided for this item.

Installation Notes

Coiled spring pins are typically installed by machinists, millwrights, or maintenance mechanics using a pin punch and hammer or a hydraulic press. Always ensure the receiving bore is clean and sized to the appropriate tolerance for the pin diameter before driving. Wear appropriate eye protection during installation, as compressed pins can release stored energy if mishandled. Remove load and power from any assembly before servicing pins retained in rotating or actuated components.
