Value Collection R57700819 Coiled Spring Pin 3/16 in 1070 Alloy

Product Description

The Value Collection R57700819 is a coiled spring pin designed for secure fastening in applications that require controlled flexibility and resistance to shock and vibration. Measuring 0.1875 inches in diameter and 1.375 inches in overall length, this pin is manufactured from 1070-1090 alloy steel with a plain finish. The coiled construction allows the pin to compress on insertion and exert consistent radial pressure against the bore wall, providing a firm, self-retaining fit without the need for adhesives or secondary fasteners. Machinists, millwrights, and maintenance technicians commonly install this type of pin in assemblies where repeated disassembly and reassembly may be required.

This coiled spring pin is suited for use in general industrial, mechanical, and light manufacturing assemblies. Typical applications include linkage joints, drive shaft connections, hinge assemblies, and component alignment fixtures across a range of equipment types. The inch measurement system and fractional 3/16-inch diameter make it compatible with standard inch-system tooling and bore specifications commonly found in North American equipment.

Key Features

• Coiled construction provides radial spring tension for a self-retaining fit in bored holes
• 1070-1090 alloy steel offers solid strength and durability for demanding mechanical environments
• 0.1875-inch (3/16-inch) diameter fits standard inch-system bores
• 1.375-inch overall length suitable for moderate-depth through-hole and blind-hole installations
• Plain finish with no coating or plating for straightforward dimensional consistency
• Does not meet military specifications — intended for commercial and industrial use

Compatibility

Designed as a standard commercial coiled spring pin for use in inch-system mechanical assemblies requiring a 3/16-inch nominal diameter pin.

Installation Notes

Installation is typically performed by machinists or mechanical maintenance personnel using a pin punch and hammer or an arbor press to drive the pin into a properly sized bore. The receiving hole should be drilled and reamed to the appropriate tolerances for coiled spring pins per applicable ASME or manufacturer standards. Always depressurize, de-energize, and lock out the equipment before pin installation or removal. Avoid reusing heavily deformed pins, as repeated compression cycling can reduce the retention force of coiled spring pins.
