Value Collection R57700841 Coiled Spring Pin 7/32 in

Product Description

The VALUE COLLECTION R57700841 is a coiled spring pin designed for use in mechanical assemblies requiring a reliable, self-retaining fastener. The coiled design allows the pin to compress during installation and expand against the bore wall, creating a secure interference fit without the need for additional fasteners or adhesives. Manufactured from 1070-1090 alloy steel with a plain finish, this pin measures 0.2188 inches (7/32 inch) in diameter and 1-3/4 inches in overall length. It is suited for production and maintenance applications where consistent pin retention and controlled flexibility under load are required.

Coiled spring pins are commonly installed in a wide range of industrial and mechanical applications, including alignment fixtures, shaft assemblies, linkages, and hinged mechanisms across general manufacturing, equipment maintenance, and machine repair environments. The 0.2188-inch diameter and 1-3/4-inch length make this pin compatible with standard 7/32-inch nominal bore applications. Installations are measured in the inch system of measurement. This pin does not meet military specifications and is intended for commercial and industrial use.

Key Features

• Coiled construction provides a self-retaining interference fit in the host bore
• 0.2188 inch (7/32 inch) diameter for use in standard nominal 7/32-inch bores
• 1-3/4 inch overall length suits moderate-depth pin hole applications
• 1070-1090 alloy steel construction offers strength and durability in mechanical assemblies
• Plain finish with no coating for straightforward dimensional consistency
• Inch-system dimensioning for compatibility with standard U.S. tooling and gauging

Compatibility

Designed as a standard coiled spring pin for use in any mechanical assembly requiring a 7/32-inch nominal diameter pin hole and a 1-3/4-inch engagement depth. Verify host material, bore tolerance, and load requirements before installation.

Installation Notes

Coiled spring pins are typically installed by maintenance technicians and mechanical assemblers using a pin punch and hammer or an arbor press. Always ensure the receiving bore is clean, correctly sized, and free of burrs before driving the pin. Do not exceed the designed bore depth, and support the workpiece adequately to prevent deformation during installation. Remove and replace pins that show signs of fatigue cracking, deformation, or loss of spring tension.
