Value Collection R57700853 Coiled Spring Pin 0.25in X 2in

Product Description

The VALUE COLLECTION R57700853 is a coiled spring pin engineered for reliable fastening and alignment in mechanical assemblies. Manufactured from 1070-1090 alloy steel with a plain finish, this pin measures 0.25 inches in diameter and 2 inches in length. Coiled spring pins are designed to absorb shock and vibration by flexing radially under load, maintaining a secure fit in the host material. They are installed by pressing into a drilled hole slightly smaller than the pin diameter, allowing the coiled body to compress and grip the bore walls. Maintenance technicians, machinists, and assembly professionals install these pins across a broad range of industrial and mechanical applications.

Coiled spring pins are commonly used in assemblies where components must be pinned, aligned, or retained without the use of solid dowel pins. Typical applications include gear-to-shaft connections, pivot points, linkage assemblies, and general mechanical fastening in both light and heavy-duty equipment. The 1070-1090 alloy steel construction provides adequate strength and flexibility for standard industrial duty cycles. This pin ships individually per package quantity and is subject to a minimum order quantity of 25 units.

Key Features

• Coiled spring design absorbs radial shock and vibration loads in dynamic assemblies
• 1070-1090 alloy steel construction balances hardness and flexibility for reliable installation
• Plain finish suitable for general-purpose use in dry or lightly lubricated environments
• 0.25 inch diameter by 2 inch length fits standard 1/4 inch nominal bore applications
• Inch system of measurement for compatibility with standard drill and reamer sizing

Compatibility

Designed as a standard coiled spring pin for use in any mechanical assembly requiring a 0.25 inch nominal diameter pin hole and a 2 inch engagement length.

Installation Notes

Coiled spring pins are installed by a machinist or maintenance technician using a pin driver or arbor press. Ensure the receiving hole is drilled to the correct nominal diameter per applicable engineering tolerances before installation. The pin should be driven straight and flush or to the specified depth without excessive hammer impact that could distort the coil. Always de-energize and lock out any equipment before servicing assemblies containing these pins.
