Value Collection c57700921 Coiled Spring Pin 3in 1/4in

Product Description

The VALUE COLLECTION c57700921 is a coiled spring pin manufactured from 1070-1090 alloy steel with an uncoated finish. Coiled spring pins are slotted, rolled fasteners that compress on insertion and expand to grip the walls of a drilled hole, providing secure retention through radial spring tension. This pin measures 3 inches in overall length with a 1/4 inch diameter. It is installed in mechanical assemblies, fixtures, and equipment where a removable or permanent pin-type fastener is required. Machinists, millwrights, and maintenance technicians are the primary installers across industrial and commercial applications.

Coiled spring pins of this type are commonly used in shaft-to-hub connections, hinge pivots, clevis linkages, and general mechanical retention tasks. The 1070-1090 alloy steel construction provides strength and fatigue resistance suited to dynamic or vibrating assemblies. The uncoated finish is appropriate for indoor or dry-environment applications where corrosion exposure is limited. This pin ships in packages of 25 units, making it practical for shop stock and production line use.

Key Features

• 3 inches overall length and 1/4 inch diameter for standard mechanical retention applications
• 1070-1090 alloy steel construction delivers strength and spring fatigue resistance
• Coiled design compresses on insertion and expands to grip hole walls without adhesive or threading
• Uncoated finish suitable for controlled-environment or lubricated assemblies
• Sold in 25-unit packages with a minimum order quantity of 1 package

Compatibility

Designed as an OEM-style replacement or standard-stock coiled spring pin for use in any mechanical assembly requiring a 1/4 inch diameter, 3 inch long spring pin retention solution.

Installation Notes

Coiled spring pins are installed by machinists or maintenance technicians using a pin punch and hammer or a hydraulic press. The receiving hole must be drilled to the correct nominal diameter per manufacturer tolerances to ensure proper radial grip. Wear appropriate eye protection during installation. To remove, drive the pin out with a correctly sized punch to avoid deforming the bore or surrounding material.
