Value Collection R57700845 Coiled Spring Pin 0.25in 1in

Product Description

The VALUE COLLECTION R57700845 is a coiled spring pin manufactured from 1070-1090 alloy steel with a plain finish. The pin measures 0.25 inches in diameter and 1 inch in overall length. Coiled spring pins are slotted, cylindrical fasteners that compress during installation and exert radial pressure against the hole wall to maintain retention. They are used across mechanical assemblies, machine components, and structural connections where a reliable, removable pin fastener is required. Machinists, millwrights, and assembly technicians install these pins in production and maintenance applications.

This pin is suited for general industrial and mechanical assembly applications where a standard inch-series coiled spring pin is specified. The 1070-1090 alloy steel construction provides good hardness and toughness for moderate-load retention tasks. The plain finish is appropriate for interior or protected environments where corrosion resistance is not a primary concern. This part does not meet military specifications and is intended for commercial-grade applications.

Key Features

• 0.25 inch diameter and 1 inch overall length in standard inch-series sizing
• 1070-1090 alloy steel construction for reliable hardness and toughness
• Plain finish for use in standard commercial and industrial environments
• Coiled design exerts radial spring force against bore wall for secure retention
• Does not meet military specifications — suitable for commercial-grade use

Compatibility

Designed as a standard inch-series coiled spring pin for general commercial and industrial mechanical assemblies requiring a 0.25 inch diameter, 1 inch long spring pin fastener.

Installation Notes

Coiled spring pins are installed by machinists or maintenance technicians using a pin punch and hammer or an arbor press. The receiving hole should be drilled to the appropriate tolerance for a coiled spring pin fit per applicable standards. Always ensure the assembly is de-energized and secured before driving pins into or out of live machinery. Do not reuse heavily deformed pins removed from service.
