Value Collection R57700831 Coiled Spring Pin Alloy Steel

Product Description

The VALUE COLLECTION R57700831 is a coiled spring pin designed for use in mechanical assemblies where a reliable, fatigue-resistant fastening pin is required. Manufactured from 1070-1090 alloy steel with a plain finish, this pin measures 0.2188 inches in diameter and 3/4 inches in overall length. The coiled design allows the pin to compress during installation, exerting radial pressure against the host bore to maintain a secure fit without adhesives or additional hardware. It is a standard inch-measurement fastener suited for maintenance, repair, and original equipment assembly work across a wide range of industrial and mechanical applications.

Coiled spring pins are commonly installed in shafts, hinges, linkages, and other mechanical joints found in industrial equipment, agricultural machinery, and general manufacturing environments. The 0.2188 inch diameter and 3/4 inch length make this pin appropriate for moderate-load applications where vibration resistance and consistent retention force are needed. Technicians and machinists working on equipment requiring inch-series hardware will find this pin compatible with standard 7/32 inch bore applications.

Key Features

• 0.2188 inch (7/32 inch fractional) nominal diameter for use in standard inch-series bores
• 3/4 inch overall length suitable for moderate-depth assemblies
• 1070-1090 alloy steel construction provides strength and fatigue resistance
• Coiled design compresses on installation, creating consistent radial retention force
• Plain finish suitable for interior and protected mechanical assemblies

Compatibility

Designed as a standard inch-series coiled spring pin for mechanical assemblies requiring a 0.2188 inch diameter retention pin in a 3/4 inch bore depth.

Installation Notes

Coiled spring pins are typically installed by machinists or maintenance technicians using a pin punch and hammer or a press. Power down and de-energize any equipment before servicing components that contain spring pins. Ensure the bore diameter is clean and within tolerance before driving the pin to avoid deformation or bore damage. Worn or oversized bores will reduce retention force and should be addressed before installation.
