Value Collection R57700789 Coiled Spring Pin Alloy Steel

Product Description

The VALUE COLLECTION R57700789 is a coiled spring pin manufactured from 1070-1090 alloy steel with a plain finish. Coiled spring pins are slotted cylindrical fasteners that compress upon insertion and exert radial pressure against the bore wall to maintain their position. This pin measures 0.1563 inches (5/32 inches fractional) in diameter and 11/16 inches in overall length. It is used in mechanical assemblies requiring a removable or semi-permanent pin fastener where vibration resistance and controlled retention force are important. Installation and removal are handled with standard pin punch tools. This part is sold individually per package unit.

Coiled spring pins are commonly used across a wide range of mechanical and industrial applications including HVAC equipment assemblies, pump and valve linkages, motor drive components, and general sheet metal or machined part assemblies. They are appropriate for use in both light-duty and moderate-duty installations where an alloy steel fastener with elastic retention characteristics is specified. This pin does not meet military specifications and is intended for commercial and industrial use. Trade mechanics, millwrights, and equipment technicians typically source these pins for repair and OEM-style replacement work.

Key Features

• Coiled spring design provides radial retention force without permanent deformation of the bore
• 1070-1090 alloy steel construction offers suitable hardness and spring characteristics for commercial applications
• 0.1563 inches (5/32 inches) diameter fits standard bore sizes for this pin class
• 11/16 inches overall length suits shallow-to-moderate depth pin installations
• Plain finish — no coating or plating — compatible with a wide range of assembly environments
• Sold per piece, available in multiples of 100 to support production and service stock quantities

Compatibility

Designed as an OEM-style replacement or service stock coiled spring pin for mechanical assemblies requiring a 0.1563-inch diameter pin in 1070-1090 alloy steel with a plain finish.

Installation Notes

Coiled spring pins are installed using a pin punch and hammer or an arbor press — always align the pin squarely with the bore before driving to avoid deformation. Power down and de-energize any equipment fully before disassembling components to access pin locations. Wear appropriate eye protection when driving or removing spring pins, as compressed pins can release energy upon extraction. Reuse of coiled spring pins is generally acceptable if the pin shows no cracking, flattening, or permanent diameter reduction.
