Value Collection P20006 Locking Cotter Pin 1/2 in Shaft

Product Description

The VALUE COLLECTION P20006 is a locking cotter pin designed to secure fastener assemblies against loosening from vibration, rotation, or axial movement. Built from RC 60-70 spring steel with a zinc-plated finish, this pin provides reliable retention in demanding mechanical environments. It features a 1/2-inch shaft diameter, an overall length of 1.42 inches, and a wire diameter of 0.062 inches. The ring diameter ranges from 0.51 to 0.52 inches for a snug fit over standard clevis pins and fastener shafts. Maintenance technicians, millwrights, and trade professionals install this type of hardware in equipment assemblies where a standard cotter pin requires positive locking action.

This locking cotter pin is suited for use in mechanical assemblies across HVAC equipment, pump linkages, fan blade hubs, valve actuators, and general industrial machinery. Its compact size makes it appropriate for residential and light commercial equipment applications where a 1/2-inch shaft pin is specified. The zinc-plated finish provides basic corrosion resistance in indoor and sheltered outdoor installations. Sold individually per package, with a minimum order quantity of 100 units, making it practical for shop stock or fleet service inventory.

Key Features

• Locking cotter design resists loosening under vibration and rotational load
• RC 60-70 spring steel construction for consistent clamping force and durability
• Zinc-plated finish provides corrosion resistance in typical service environments
• 1/2-inch shaft diameter with ring diameter of 0.51 to 0.52 inches for precise fitment
• Wire diameter of 0.062 inches for reliable retention without oversizing
• Compact 1.42-inch length suitable for tight mechanical clearances

Compatibility

Designed as a standard locking cotter pin for use on 1/2-inch diameter shafts in mechanical fastener assemblies where positive pin retention is required.

Installation Notes

Installation is typically performed by millwrights, maintenance technicians, or trade professionals servicing mechanical equipment. De-energize and lock out all equipment before servicing any fastener assembly. Insert the pin fully through the shaft hole and engage the locking ring to confirm secure retention before returning the assembly to service. Inspect the pin for deformation or corrosion at each service interval and replace if any wear is observed.
