Value Collection R57700809 Coiled Spring Pin

Product Description

The VALUE COLLECTION R57700809 is a coiled spring pin designed for use in mechanical assemblies requiring reliable, vibration-resistant fastening. Manufactured from 1070-1090 alloy steel with a plain finish, this pin measures 0.1875 inches in diameter and 0.75 inches in length. The coiled construction allows the pin to compress during installation and exert radial pressure against the hole wall, creating a secure interference fit without permanent deformation of the host material. Machinists, millwrights, and assembly technicians install these pins in a wide range of production and maintenance applications.

Coiled spring pins are used in both light and heavy-duty mechanical assemblies across industrial, agricultural, and equipment manufacturing environments. Common applications include shaft-to-collar connections, linkage assemblies, hinges, and retention applications in metal fabricated components. The 3/16-inch fractional diameter makes this pin a standard size suitable for frequent use in general-purpose fastening work where controlled retention force is required.

Key Features

• Coiled design provides radial spring force for a secure interference fit in drilled holes
• 1070-1090 alloy steel construction offers good hardness and wear resistance for industrial use
• Plain finish with no coating or plating, suitable for dry or lightly lubricated applications
• 0.1875-inch diameter corresponds to standard 3/16-inch fractional drill sizing for straightforward hole prep
• Compact 0.75-inch length fits tight clearance assemblies where pin protrusion must be minimized

Compatibility

Designed as a standard-size coiled spring pin for general-purpose mechanical assemblies requiring a 0.1875-inch diameter hole and 0.75-inch pin engagement depth in alloy steel or compatible base materials.

Installation Notes

Coiled spring pins are installed by machinists and mechanical assembly technicians using a pin punch and hammer or a pneumatic press. Ensure the receiving hole is drilled or reamed to the correct diameter to achieve proper interference fit. De-burr and clean the hole before pressing the pin to avoid galling or misalignment. Remove all energy sources and secure any moving components before servicing assemblies that contain spring pins.
