Value Collection R57700849 Coiled Spring Pin 0.25in 1.25in

Product Description

The VALUE COLLECTION R57700849 is a coiled spring pin designed for use in mechanical assemblies where reliable retention and alignment are required. Measuring 0.25 inches in diameter and 1.25 inches in length, this pin is manufactured from 1070-1090 alloy steel with a plain finish. Coiled spring pins are engineered to compress during installation and exert radial pressure against the hole wall, creating a secure, vibration-resistant fit. This part is handled by machinists, maintenance technicians, and mechanical assemblers working across industrial, manufacturing, and equipment repair applications.

This coiled spring pin suits a wide range of general-purpose fastening and alignment tasks in metal assemblies, fixtures, jigs, and mechanical components. It is appropriate for use in both production environments and field repair situations where a standardized inch-series pin is required. The 1070-1090 alloy steel construction provides the hardness and spring characteristics necessary for repeated installation and removal cycles without permanent deformation.

Key Features

• 0.25 inch nominal diameter for standard inch-series hole patterns
• 1.25 inch overall length suits moderate-depth retention applications
• 1070-1090 alloy steel construction delivers reliable spring force and wear resistance
• Plain finish suitable for use in dry or lightly lubricated assemblies
• Coiled design allows radial compression for secure press-fit retention without adhesive

Compatibility

Designed as a standard inch-series coiled spring pin for general mechanical assembly and equipment maintenance applications where a 0.25 inch diameter coiled pin is specified.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a pin driver or arbor press sized for the nominal pin diameter. The receiving hole should be drilled and reamed to the tolerance specified for coiled spring pins per applicable ASME or ISO standards. Power down or de-energize any equipment before servicing assemblies that contain spring pins. Avoid reusing pins that have been deformed beyond their elastic limit during removal.
