Value Collection R57700765 Coiled Spring Pin 0.125 in

Product Description

The VALUE COLLECTION R57700765 is a coiled spring pin designed for use in mechanical assemblies where a reliable, removable fastener is required. The pin measures 0.125 inches in diameter and 0.375 inches in length, and is manufactured from 1070-1090 alloy steel with a plain finish. Coiled spring pins apply radial pressure against the wall of the receiving hole, distributing stress evenly along the pin body. This design allows the pin to absorb shock and vibration loads without permanent deformation, making it suitable for repetitive or dynamic load applications. Maintenance technicians, millwrights, and mechanical assemblers typically install these fasteners.

This coiled spring pin is used in industrial machinery, equipment assemblies, and mechanical linkages where alignment or retention of components is required. It fits applications calling for a 1/8-inch nominal diameter roll pin of standard length. The plain finish is appropriate for indoor or controlled-environment applications where no additional corrosion resistance is specified. This pin is sold in single unit packaging with a minimum order quantity of 100 pieces.

Key Features

• Coiled spring design distributes radial stress along the full pin length for improved fatigue resistance
• 1070-1090 alloy steel construction provides high tensile strength suitable for industrial fastening applications
• 0.125-inch diameter and 0.375-inch length meet common fractional inch fastener specifications
• Plain finish suitable for dry or controlled-environment installations
• Does not meet military specifications — for commercial-grade applications
• Sold per piece with a minimum order quantity of 100 units

Compatibility

Designed as a standard coiled spring pin for use in any mechanical assembly requiring a 0.125-inch diameter, 0.375-inch long roll pin in inch-measurement systems. No specific OEM compatibility data was provided for this SKU.

Installation Notes

Coiled spring pins are pressed into pre-drilled holes using an arbor press, punch, or hammer and pin driver — ensure the receiving hole diameter matches the specified nominal pin size before installation. Power down and de-energize any machinery before servicing pinned assemblies. Avoid driving pins with oversized or improvised tools that may damage the coil structure or the bore. Follow applicable equipment manufacturer service documentation when replacing fasteners in load-bearing or safety-critical assemblies.
