Value Collection R57700821 Coiled Spring Pin 0.1875 in

Product Description

The VALUE COLLECTION R57700821 is a coiled spring pin manufactured from 1070-1090 alloy steel with a plain finish. The pin measures 0.1875 inches (3/16 inch) in diameter and 1.5 inches in overall length. Coiled spring pins are slotted, rolled fasteners that compress on insertion and exert outward radial pressure against the hole wall, creating a secure, vibration-resistant fit without adhesives or secondary locking hardware. This pin is sized and finished for general industrial and mechanical assembly applications. Installation is performed by maintenance technicians and mechanical assemblers working with standard pin-and-hole fastening configurations.

Coiled spring pins of this diameter and length are used in a wide range of mechanical assemblies including drive shafts, hinges, linkages, clevis pins, and indexed positioning fixtures. They are suited for moderate-load applications where a compressible pin is preferred over solid or slotted roll pins. The plain finish makes the pin appropriate for dry or lightly lubricated indoor environments. The 3/16-inch diameter and 1.5-inch length are common in light-to-medium duty machinery and equipment assembly found in manufacturing, maintenance, and repair operations.

Key Features

• Coiled spring design compresses on insertion for a secure radial interference fit
• 0.1875 inch (3/16 inch) diameter suits standard 3/16-inch reamed or drilled holes
• 1.5-inch overall length provides sufficient engagement depth for most light-to-medium duty assemblies
• 1070-1090 alloy steel construction offers good shear strength and fatigue resistance
• Plain finish suitable for dry or lightly lubricated indoor service environments
• Does not meet military specifications — intended for commercial and industrial use

Compatibility

Designed as a standard coiled spring pin for use in any mechanical assembly requiring a 0.1875-inch diameter pin hole and 1.5-inch pin length. Confirm hole diameter and required shear strength against application requirements before installation.

Installation Notes

Coiled spring pins are typically installed by mechanical assemblers or maintenance technicians using a pin punch, arbor press, or hammer and drift. Ensure the receiving hole is clean, within tolerance, and free of burrs before driving the pin. Do not force an oversized pin into an undersized hole, as this can crack the host material or deform the pin. Follow applicable machinery safety procedures and de-energize or lock out any equipment before servicing pinned assemblies.
