Value Collection R57700855 Coiled Spring Pin 0.25in X 2.25in

Product Description

The VALUE COLLECTION R57700855 is a coiled spring pin manufactured from 1070-1090 alloy steel with a plain finish. At 0.25 inches in diameter and 2.25 inches in overall length, this pin is engineered to absorb shock and vibration through its coiled, slotted construction. The coiled design allows the pin to compress during installation and exert outward radial force against the hole wall, creating a secure, self-retaining fit. Maintenance technicians and assembly professionals across industrial, mechanical, and trade applications install these pins where reliable fastening and repeated serviceability are required.

Coiled spring pins are used in a wide range of assembly and repair applications including shaft-to-hub connections, linkage assemblies, hinge pivots, and equipment frames. Their ability to flex under load without permanent deformation makes them suitable for both light-duty and moderate-duty mechanical assemblies. This pin is sized for standard 0.25-inch diameter holes and is supplied with a plain finish suited for general-purpose use in dry or lightly lubricated environments.

Key Features

• Coiled construction provides radial spring force for a self-retaining, press-fit installation
• 1070-1090 alloy steel material delivers strength and fatigue resistance under cyclic loading
• Plain finish suitable for general-purpose mechanical assembly applications
• 0.25-inch diameter and 2.25-inch length for compatibility with standard inch-series hole patterns
• Does not meet military specifications — intended for commercial and industrial use

Compatibility

Designed as a standard commercial-grade coiled spring pin for inch-series mechanical assemblies requiring a 0.25-inch nominal diameter pin hole.

Installation Notes

Coiled spring pins are typically installed by mechanical assemblers and maintenance technicians using a pin punch and hammer or a bench press. Always ensure the receiving hole is clean and within tolerance before driving the pin. Eye protection is required during installation. To remove, drive the pin through or extract with a punch of appropriate diameter — avoid reusing pins that show visible cracking or permanent deformation.
