Value Collection MSC67704767X Threaded Taper Pin Size 7

Product Description

The VALUE COLLECTION MSC67704767X is a Size 7 threaded taper pin machined from C-12L14 steel with an uncoated finish. It features a 3/8-24 threaded end for secure fastening and positive retention when driven into a tapered hole. The large end diameter measures 0.407 inches, the neck diameter is 0.315 inches, and overall pin length is 4 inches. Taper pins of this type are used to secure hubs, collars, and mechanical assemblies to shafts, transmitting torque and preventing axial movement. Machinists, millwrights, and maintenance technicians are the primary installers of this fastener in light to medium industrial applications.

This threaded taper pin is suited for machine assemblies, gear hubs, lever arms, and similar mechanical connections where a reliable, removable pin fastener is required. The 3/8-24 threaded end accepts a standard nut to draw the pin tightly into the tapered bore and to facilitate removal during maintenance cycles. It conforms to AN386 standards, making it appropriate for both commercial and aerospace-adjacent mechanical assemblies that call out AN-specification fasteners.

Key Features

• Size 7 taper profile with 0.407-inch large end diameter for precise fit in standard taper-reamed bores
• 3/8-24 threaded end allows nut-driven installation and controlled removal
• C-12L14 free-machining steel provides good machinability and consistent dimensional tolerances
• Maximum diameter tolerance of 0.0013 inches for close-fit mechanical connections
• Conforms to AN386 standard
• Uncoated finish — suitable for applications where post-installation plating or coating will be applied, or where bare steel is acceptable

Compatibility

Designed as a standard AN386 Size 7 threaded taper pin for use in any mechanical assembly requiring a taper-reamed bore sized for a Size 7 pin with a 3/8-24 threaded end.

Installation Notes

Install this pin using a properly reamed taper bore matched to the Size 7 taper specification — a straight-drilled hole is not an acceptable substitute. Drive or press the pin into the bore until fully seated, then thread and tighten the retaining nut to secure it in place. Always de-energize and lock out machinery before installing or removing taper pins from rotating or powered assemblies. Use appropriate pin punches and extraction tools when removing worn or seized pins to avoid bore damage.
