Value Collection R57700775 Coiled Spring Pin 0.125in X 0.875in

Product Description

The VALUE COLLECTION R57700775 is a coiled spring pin manufactured from 1070-1090 alloy steel with a plain finish. Coiled spring pins are slotted, rolled fasteners that compress on installation and exert outward radial force against the host bore wall, creating a secure, vibration-resistant fit without adhesives or secondary locking hardware. This pin measures 0.125 inches in diameter and 0.875 inches in overall length. It is used in mechanical assemblies across industrial, agricultural, and general manufacturing applications. Installation is performed by maintenance technicians and assembly professionals working with pin-retained components such as clevis assemblies, shaft collars, hinges, and linkages.

This coiled spring pin is suited for light-duty to medium-duty fastening applications where a reusable, self-retaining pin is required. The 1070-1090 alloy steel construction provides adequate shear strength for standard inch-system assemblies. The plain finish is appropriate for interior, controlled-environment applications where corrosion exposure is minimal. This pin does not meet military specifications and is intended for commercial-grade use. Minimum order quantity is 100 pieces.

Key Features

• 0.125 inch diameter and 0.875 inch overall length for precision fitment in standard inch-dimensioned bores
• 1070-1090 alloy steel construction provides reliable shear resistance in mechanical assemblies
• Plain finish suitable for controlled indoor environments
• Coiled design allows radial compression on insertion for a secure, vibration-resistant hold
• Reusable and removable without specialized tooling in most applications

Compatibility

Designed as a commercial-grade coiled spring pin for standard inch-system mechanical assemblies requiring a 0.125 inch diameter pin retention solution.

Installation Notes

Install using a standard pin punch and hammer or an arbor press; ensure the host bore is clean and within the recommended tolerance for a 0.125 inch pin. Inspect the bore for burrs or deformation before seating the pin to avoid damage to the coil. De-energize or lock out any machinery before servicing pin-retained components per applicable OSHA lockout/tagout procedures.
