Value Collection MSC67704320X Threaded Taper Pin Size 6

Product Description

The VALUE COLLECTION MSC67704320X is a Size 6 threaded taper pin made from C-12L14 steel with an uncoated finish. It measures 2 inches in pin length with a large end diameter of 0.339 inches and a neck diameter of 0.253 inches. The 5/16-24 threaded end allows a nut to be tightened against the assembly, securing the pin against withdrawal. This design is well suited for applications where vibration or axial load could otherwise back the pin out. Machinists, maintenance technicians, and mechanical assemblers install these pins to lock hubs, collars, and levers onto shafts in a wide range of mechanical systems.

Threaded taper pins are used in both light industrial and precision mechanical assemblies where reliable, removable shaft-to-hub connections are required. The tapered body seats tightly in a reamed taper-pin hole, creating a self-locking fit. The 5/16-24 threaded end provides a positive mechanical retention method beyond the taper interference alone. Typical applications include machine tool components, agricultural equipment linkages, and general industrial drive assemblies where periodic disassembly is needed for maintenance.

Key Features

• Size 6 taper pin with 2-inch pin length for standard tapered-hole applications
• Large end diameter of 0.339 inches with maximum diameter tolerance of 0.0013 inches
• 5/16-24 threaded end prevents pin withdrawal under vibration or axial loading
• C-12L14 free-machining steel provides consistent dimensional accuracy and good machinability
• Uncoated finish suitable for dry or lubricated mechanical assemblies
• Manufactured to AN386 standard for dimensional conformance

Compatibility

Designed as a standard replacement or new-installation threaded taper pin for any assembly specifying a Size 6 taper pin hole reamed to AN386 dimensions with a 5/16-24 threaded fastener requirement.

Installation Notes

Threaded taper pins are installed by machinists or maintenance technicians using a reamed taper-pin hole sized to the correct taper pin number. The mating hole must be finish-reamed with a Size 6 taper pin reamer before installation. De-energize and lock out all equipment before servicing any shaft-to-hub connection. Thread a nut onto the 5/16-24 end after seating the pin to secure it against reverse movement.
