Value Collection R57700749 Coiled Spring Pin Alloy Steel

Product Description

The VALUE COLLECTION R57700749 is a coiled spring pin manufactured from 1070-1090 alloy steel with a plain finish. This pin measures 0.0938 inches (3/32 inches) in diameter and 0.625 inches in overall length. Coiled spring pins are slotted cylindrical fasteners that compress on insertion and exert radial pressure against the bore wall, creating a secure, vibration-resistant fit without permanent deformation of the host material. Machinists, millwrights, and assembly technicians use these pins to align, retain, or lock components in mechanical assemblies across industrial and commercial applications.

Coiled spring pins in this diameter and length range are commonly used in light to medium-duty mechanical assemblies where controlled retention force and reusability are required. Typical applications include shaft-to-hub alignment, gear and pulley retention, linkage assemblies, and tool fixtures. The 1070-1090 alloy steel construction provides good hardness and fatigue resistance suitable for dynamic or cyclically loaded joints. This pin is sold individually per package with a minimum order quantity of 100 units, making it appropriate for production or maintenance stock replenishment.

Key Features

• Coiled spring design exerts consistent radial pressure for vibration-resistant retention
• 0.0938 inches (3/32 inches) diameter fits standard bore sizes for this pin class
• 0.625 inches overall length suits shallow to moderate through-hole applications
• 1070-1090 alloy steel construction offers good hardness and fatigue resistance
• Plain finish with no plating or coating, suitable for dry or lubricated assemblies
• Reusable and removable without damage to the host bore under normal conditions

Compatibility

Designed as an OEM-style replacement or stock fastener for mechanical assemblies requiring a coiled spring pin with a 0.0938-inch nominal diameter and 0.625-inch length in the inch measurement system.

Installation Notes

Installation is typically performed by machinists or mechanical assembly technicians using a pin punch and hammer or an arbor press sized for the pin diameter. The bore should be clean and free of burrs before insertion to avoid deformation of the pin coils. Power down or de-energize any equipment before servicing components that retain these pins. Do not substitute a solid pin or roll pin of a different spring rate without verifying the load requirements of the application.
