Value Collection MSC67705608X Threaded Taper Pin Size 9

Product Description

The VALUE COLLECTION MSC67705608X is a Size 9 threaded taper pin manufactured from C-12L14 steel with an uncoated finish. It features a 1/2-20 threaded end that accepts a nut for secure retention, a large-end diameter of 0.589 inches, a neck diameter of 0.430 inches, and a pin length of 5 inches. The tapered body conforms to AN386 standards, ensuring dimensional consistency for precision mechanical assemblies. This pin is installed by machinists, maintenance technicians, and millwrights wherever a removable, load-bearing connection between shafts, hubs, or linkages is required.

Threaded taper pins are used in mechanical assemblies that require secure, repeatable alignment and the ability to be driven out and reinstalled without damaging mating components. Common applications include shaft-to-hub connections on machinery, agricultural equipment, and industrial drives. The C-12L14 free-machining steel construction makes this pin well suited for high-volume production and maintenance environments. The AN386 standard designation makes it a direct fit for aerospace-style and industrial hardware specifications that call out this pin series.

Key Features

• AN386 standard compliance ensures dimensional accuracy and interchangeability across assemblies
• 1/2-20 threaded end accepts a standard nut for positive retention and controlled removal
• C-12L14 free-machining steel provides consistent hardness and machinability
• Large-end diameter of 0.589 inches with a maximum diameter tolerance of 0.0013 inches
• Uncoated finish suitable for assemblies where post-installation coating or press-fit retention is used
• 5-inch pin length accommodates deeper hub or flange assemblies

Compatibility

Designed as a standard AN386 Size 9 threaded taper pin for use in mechanical assemblies that specify this pin size, thread, and diameter. Confirm hole taper and thread engagement requirements against assembly drawings before installation.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a taper reamer to prepare the mating hole before driving the pin. Power down and de-energize all connected equipment before servicing any shaft or hub assembly. Drive the pin with a hammer and pin punch until fully seated, then thread the nut to the specified retention requirement. Do not force an oversized pin into an undersized hole, as this can crack hubs or distort bores.
