Value Collection R57700791 Coiled Spring Pin Alloy Steel

Product Description

The VALUE COLLECTION R57700791 is a coiled spring pin designed for use in mechanical assemblies requiring a secure, vibration-resistant fastener. Measuring 0.1563 inches in diameter and 0.75 inches in length, this pin is manufactured from 1070-1090 alloy steel with a plain finish. The coiled construction allows the pin to compress during installation and apply radial pressure against the host material, creating a self-retaining fit. It is a standard inch-system fastener installed by machinists, maintenance technicians, and assembly professionals across a wide range of industrial and mechanical applications.

This coiled spring pin is suited for use in shaft-to-hub connections, hinges, linkages, and general mechanical assemblies where a removable or permanent retention pin is needed. The 5/32-inch fractional diameter makes it compatible with standard drilled holes in that size. It is appropriate for both light-duty and moderate-duty applications in manufacturing, maintenance, and equipment repair environments where alloy steel strength is required.

Key Features

• Coiled spring design provides radial pressure and self-retaining fit in drilled holes
• 1070-1090 alloy steel construction for reliable strength in mechanical assemblies
• 0.1563 inches (5/32 inch) nominal diameter fits standard drilled hole sizes
• 0.75 inches overall length suitable for moderate material thickness applications
• Plain finish with no coating, appropriate for dry or lubricated environments
• Inch system of measurement for compatibility with standard imperial tooling

Compatibility

Designed as a standard inch-system coiled spring pin for use in drilled holes sized to accept a 5/32-inch diameter pin in general mechanical and industrial 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 tolerance for a coiled pin fit. Ensure the assembly is de-energized and secured before pin installation or removal. Do not use an oversized punch that could deform the pin coils or damage the host bore.
