Value Collection MSC67707000X Size 9 Threaded Taper Pin

Product Description

The VALUE COLLECTION MSC67707000X is a Size 9 threaded taper pin machined from 303 grade 18-8 stainless steel with a passivated finish. It features a 1/2-20 threaded end and a large end diameter of 0.589 inches, with a 2.5-inch pin length and a neck diameter of 0.43 inches. Taper pins of this type are used to lock hubs, collars, and mechanical assemblies onto shafts, transmitting torque and preventing axial movement. The passivated finish improves corrosion resistance without adding a coating layer, making this pin suitable for demanding or moisture-exposed environments. Machinists, millwrights, and maintenance technicians working on precision mechanical assemblies are the typical installers.

This taper pin is suited for use in mechanical drives, conveyor assemblies, pump shafts, and general industrial machinery where a reliable, removable locking fastener is required. The threaded end allows the pin to be extracted with a nut and puller rather than driven out with force, making it practical in assemblies that require periodic disassembly or maintenance access. It conforms to AN386 standards and is appropriate for both original installation and replacement applications in light-to-medium duty mechanical systems.

Key Features

• Size 9 taper pin with 0.589-inch large end diameter per AN386 standard
• 1/2-20 threaded end for mechanical extraction using a standard nut and puller
• 303 grade 18-8 stainless steel construction for corrosion resistance
• Passivated finish removes free iron and improves surface corrosion resistance
• Maximum diameter tolerance of 0.0013 inches for precise fitment in reamed holes
• 2.5-inch pin length with 0.43-inch neck diameter

Compatibility

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

Installation Notes

Installation requires a properly reamed taper hole sized to match the pin taper; never force a taper pin into an undersized or non-tapered bore. The mating assembly should be secured and the shaft should be locked against rotation before driving or threading the pin into position. Use appropriate hand tools or a pin driver; do not use impact tools on the pin body. Follow applicable machinery safety lockout/tagout procedures before servicing any assembly containing this fastener.
