Value Collection MSC67705368X Threaded Taper Pin Size 9

Product Description

The VALUE COLLECTION MSC67705368X is a Size 9 threaded taper pin manufactured from C-12L14 steel with an uncoated finish. Taper pins provide a reliable, self-locking method of securing hubs, collars, and mechanical components to shafts. This pin features a 1/2-20 threaded end that accepts a mating nut, allowing controlled extraction without damage to the assembly. The large end diameter measures 0.589 inches, the neck diameter measures 0.43 inches, and the pin length is 2 inches. Maximum diameter tolerance is held to 0.0013 inches, supporting precise fitment in close-tolerance bored holes. It conforms to AN386 standards and is suited for use by machinists, maintenance technicians, and production assembly crews.

This threaded taper pin is used in mechanical assemblies where positive retention and controlled disassembly are required. Typical applications include securing sprockets, gears, couplings, and collars on shafts in industrial machinery, agricultural equipment, and general fabrication. The threaded end allows a nut to drive extraction without the need for a punch, making it preferable in assemblies that require periodic service. The uncoated C-12L14 steel construction offers good machinability and is appropriate for dry or lightly lubricated environments where corrosion resistance is not a primary concern.

Key Features

• Size 9 taper pin with 0.589-inch large end diameter and 2-inch pin length
• 1/2-20 threaded end allows nut-driven extraction without a punch or drift
• C-12L14 steel construction provides consistent machinability and dimensional stability
• Maximum diameter tolerance of 0.0013 inches supports close-tolerance bored hole fitment
• Conforms to AN386 standard for threaded taper pins
• Uncoated finish suited for dry or lightly lubricated mechanical assemblies

Compatibility

Designed as an AN386-standard Size 9 threaded taper pin for use in mechanical assemblies requiring a 0.589-inch large end diameter taper-bored hole and a 1/2-20 threaded extraction nut.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a reamed taper hole matched to the pin size. The mating hole must be finish-reamed to the correct taper before driving the pin. Verify shaft and hub alignment before seating the pin, and do not overdrive, as this can distort the assembly or fracture the pin. Thread a nut onto the 1/2-20 end before installation to protect the threads during driving, and use the nut for controlled extraction during service.
