Value Collection R57700803 Coiled Spring Pin 0.1875 in

Product Description

The VALUE COLLECTION R57700803 is a coiled spring pin designed for use in mechanical assemblies requiring a secure, vibration-resistant fastening solution. Measuring 0.1875 inches in diameter and 0.5 inches in overall length, this pin is manufactured from 1070-1090 alloy steel with a plain finish. The coiled design allows the pin to compress under load and exert consistent radial pressure against the bore wall, providing a reliable fit in both static and dynamic applications. It is installed by maintenance technicians, machinists, and mechanical assemblers working on equipment requiring precision fastener solutions.

This coiled spring pin is suited for general industrial and mechanical assembly applications where a slotted or solid pin may not provide adequate retention. Typical use cases include shaft-to-hub connections, linkage assemblies, hinges, and fixture components. The 1070-1090 alloy steel construction offers good hardness and strength for moderate-load applications in both light industrial and OEM manufacturing environments. This pin does not meet military specifications and is intended for standard commercial applications.

Key Features

• 0.1875 inch (3/16 inch) diameter for compatibility with standard bore sizes
• 0.5 inch overall length suitable for shallow-depth pin applications
• 1070-1090 alloy steel construction for strength and hardness in commercial use
• Coiled design provides consistent radial spring force for secure retention
• Plain finish with no additional coating or plating
• Does not meet military specifications — rated for standard commercial use

Compatibility

Designed as a standard commercial coiled spring pin for general mechanical assembly applications where a 0.1875 inch diameter, 0.5 inch long pin is specified.

Installation Notes

Install using a pin driver or arbor press sized appropriately for the 0.1875 inch diameter. Ensure the receiving bore is clean and dimensionally correct before driving the pin to avoid distortion. Wear appropriate eye protection during installation. Remove all power or mechanical energy from the assembly before performing pin installation or removal.
