Value Collection R57700743 Coiled Spring Pin 0.0938 in

Product Description

The VALUE COLLECTION R57700743 is a coiled spring pin designed for securing components in assemblies where controlled flexibility and radial load distribution are required. The pin measures 0.0938 inches in diameter and 0.4375 inches in length, constructed from 1070-1090 alloy steel with a plain finish. Coiled spring pins compress radially on insertion, distributing stress across multiple coils rather than concentrating it at a single point. This design resists fatigue under dynamic or vibrating loads. The part is sold individually and is ordered in minimum quantities of 100 units, making it appropriate for production or maintenance stocking applications. Machinists, maintenance technicians, and assembly professionals are the typical installers.

This coiled spring pin is suited for use in light to medium-duty fastening applications across mechanical assemblies, including pivot points, hinge assemblies, clevis connections, and gear or pulley retention. The 3/32-inch fractional diameter and 7/16-inch length make it appropriate for compact assemblies with limited bore depth. Applications span general industrial, agricultural equipment, and fluid-handling hardware where standard inch-measurement fasteners are specified. It does not meet military specifications and is intended for commercial-grade applications.

Key Features

• Coiled construction distributes radial stress across multiple coils for improved fatigue resistance
• 0.0938 inch (3/32 inch) nominal diameter fits standard inch-series bored holes
• 0.4375 inch overall length suits compact assemblies with shallow bore requirements
• 1070-1090 alloy steel provides good hardness and tensile strength for mechanical fastening duty
• Plain finish with no coating or plating applied
• Minimum order quantity of 100 units supports production stocking and bulk maintenance supply

Compatibility

Designed as a standard inch-series coiled spring pin for use in commercial mechanical assemblies requiring a 0.0938 inch nominal pin diameter. Verify bore diameter and depth against assembly drawings before installation.

Installation Notes

Installation is typically performed by machinists or mechanical technicians using a pin punch and hammer or an arbor press. The receiving bore should be clean and free of burrs before driving the pin. Always support the workpiece firmly to prevent deformation of surrounding material during installation. De-energize and lock out any equipment before servicing assemblies that contain spring pins.
