Value Collection R57700773 Coiled Spring Pin Alloy Steel

Product Description

The VALUE COLLECTION R57700773 is a coiled spring pin manufactured from 1070/1090 alloy steel with a plain finish. Coiled spring pins are slotted, rolled fasteners designed to absorb shock and vibration by flexing under load, then returning to their original diameter to maintain a secure press fit in the host bore. This pin measures 0.125 inches in diameter and 11/16 inches in overall length. It is sized for light-duty to medium-duty fastening applications where a reliable, reusable retention solution is required. Machinists, maintenance technicians, and assembly workers install these pins in production and repair environments across industrial, mechanical, and general manufacturing settings.

Coiled spring pins of this size are commonly used in mechanical assemblies, jigs, fixtures, hinges, linkages, and shaft-to-collar connections. The 0.125-inch diameter suits close-tolerance bores in light mechanical components. The 1070/1090 alloy steel construction provides good tensile strength and fatigue resistance without the brittleness associated with solid roll pins. This pin is sold individually but carries a minimum order quantity of 100 units, making it appropriate for production runs, maintenance kits, and service shop inventory.

Key Features

• Coiled spring design absorbs shock and vibration while maintaining press-fit retention
• 0.125-inch diameter and 11/16-inch overall length for light mechanical bore applications
• 1070/1090 alloy steel construction for reliable tensile strength and fatigue resistance
• Plain finish — no coating or plating that could affect bore fit tolerances
• Does not meet military specifications — suitable for commercial and industrial use
• Minimum order quantity of 100 units supports production and stocking requirements

Compatibility

Designed as a standard coiled spring pin for use in any application requiring a 0.125-inch nominal diameter spring pin in inch-system mechanical assemblies.

Installation Notes

Coiled spring pins are installed by mechanical technicians and machinists using a pin punch and hammer or an arbor press. Always confirm bore diameter and depth before installation to ensure proper engagement and retention. Wear appropriate eye protection when driving pins. Do not overdrive the pin beyond the specified seating depth, as this can damage the bore or deform the pin coil.
