Value Collection R57700753 Coiled Spring Pin Alloy Steel

Product Description

The VALUE COLLECTION R57700753 is a coiled spring pin designed for use in mechanical assemblies where a removable or semi-permanent fastening solution is required. The pin measures 0.0938 inches in diameter and 0.75 inches in overall length. It is manufactured from 1070-1090 alloy steel with a plain finish. Coiled spring pins work by compressing radially as they are driven into a drilled hole, then exerting outward spring force to maintain their position. Machinists, millwrights, and maintenance technicians install these pins to align components, retain shaft assemblies, or lock mating parts in position.

This pin is suited for general industrial and mechanical maintenance applications. Typical uses include component alignment in shaft-and-hub assemblies, hinge pins in fabricated enclosures, and detent retention in tooling fixtures. The 3/32-inch fractional diameter makes it a common choice for light- to medium-duty assemblies where controlled retention force is needed without permanent fastening. The plain finish is appropriate for interior or protected mechanical environments.

Key Features

• Coiled spring design provides radial retention force without adhesives or secondary fasteners
• 0.0938 inches (3/32 inches) diameter fits standard drilled hole applications
• 0.75 inches overall length suits shallow-to-medium depth bores
• 1070-1090 alloy steel construction for strength and spring-back performance
• Plain finish suitable for protected mechanical environments
• Inch system of measurement for compatibility with standard U.S. tooling and blueprints

Compatibility

Designed as a general-purpose coiled spring pin for use in standard drilled holes requiring a 3/32-inch nominal diameter fastener in light- to medium-duty mechanical assemblies.

Installation Notes

Coiled spring pins are typically 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 nominal diameter per applicable engineering tolerances before installation. Ensure the work piece is securely fixtured before driving the pin to avoid misalignment. Removal requires a correctly sized pin punch to avoid deforming the bore.
