Value Collection MSC67704288X Threaded Taper Pin Size 6

Product Description

The VALUE COLLECTION MSC67704288X is a Size 6 threaded taper pin made from C-12L14 steel with an uncoated finish. It features a 5/16-24 external thread, a large end diameter of 0.339 inches, a neck diameter of 0.253 inches, and a pin length of 1.75 inches. Taper pins are precision fasteners used to secure hubs, collars, and other components to shafts, or to locate mating parts in fixed alignment. The threaded end accepts a nut to retain the pin under load. This part meets AN386 standards and is installed by machinists, millwrights, and maintenance technicians across industrial and mechanical service applications.

Threaded taper pins in Size 6 are commonly used in mechanical assemblies requiring repeatable disassembly and precise angular or axial alignment. Typical applications include securing handwheels or levers to shafts, pinning gear hubs, and locating fixtures in manufacturing equipment. The C-12L14 free-machining steel construction suits general-purpose industrial use where corrosion exposure is limited or where the assembly is protected by surrounding structure or lubricants. The uncoated finish is standard for interior mechanical applications.

Key Features

• Size 6 taper pin with 0.339 inch large end diameter for precise shaft and hub location
• 5/16-24 threaded end allows nut retention to prevent backing out under vibration or load
• C-12L14 free-machining steel provides consistent dimensional accuracy and machinability
• Maximum diameter tolerance of 0.0013 inches ensures close-fit assembly performance
• Meets AN386 standard for threaded taper pin geometry and dimensional compliance
• 1.75 inch pin length suits medium-diameter shaft and hub combinations

Compatibility

Designed as an OEM-style replacement or direct-fit fastener for mechanical assemblies requiring a Size 6 threaded taper pin conforming to AN386 specifications.

Installation Notes

Threaded taper pins are installed by machinists or maintenance technicians using a pin punch and hammer to drive the pin into a reamed taper hole, followed by threading a nut onto the exposed end. The mating hole must be reamed to the correct taper before installation. Ensure the shaft and hub assembly is fully depowered and secured before driving or removing the pin. Do not force an oversized pin into an under-reamed hole, as this can crack the hub or distort the shaft.
