Value Collection R57700851 Coiled Spring Pin 0.25in

Product Description

The VALUE COLLECTION R57700851 is a coiled spring pin designed for use in mechanical assemblies requiring reliable fastening and vibration resistance. Manufactured from 1070-1090 alloy steel with a plain finish, this pin measures 0.25 inches in diameter and 1.75 inches in overall length. The coiled construction allows the pin to compress during insertion and exert radial pressure against the host bore, creating a secure, self-retaining fit. Installers in general mechanical, industrial, and trade maintenance applications rely on coiled spring pins where consistent holding force and reusability are required.

This coiled spring pin is suited for use in shaft-to-hub connections, pivot assemblies, linkage mechanisms, and similar mechanical joints found in light industrial equipment, HVAC machinery components, and plumbing or fluid-handling assemblies. The inch-system sizing and standard 0.25-inch diameter make it compatible with common bore specifications used across a wide range of manufactured equipment. No military specification compliance is indicated for this pin.

Key Features

• Coiled spring design provides self-retaining fit through radial expansion against bore walls
• 1070-1090 alloy steel construction for strength and durability in mechanical applications
• 0.25-inch diameter and 1.75-inch length suit common shaft and linkage bore sizes
• Plain finish appropriate for indoor or protected-environment mechanical assemblies
• Inch system of measurement for compatibility with standard US tooling and bores

Compatibility

Designed as a standard inch-series coiled spring pin for general mechanical and industrial fastening applications where a 0.25-inch diameter, 1.75-inch long coiled pin is specified.

Installation Notes

Coiled spring pins are typically installed by maintenance technicians and mechanical assemblers using a pin punch and hammer or a press. Always ensure the host bore diameter matches the nominal pin specification before installation. Support the workpiece adequately to prevent component damage during driving. Remove power or mechanical energy from any assembly before servicing pins in moving mechanisms.
