Value Collection MSC67707042X Taper Pin Size 9 Stainless

Product Description

The VALUE COLLECTION MSC67707042X is a Size 9 threaded taper pin manufactured from Grade 303, 18-8 stainless steel with a passivated finish. The large end diameter measures 0.589 inches, and the pin body is 3 inches in length. The 1/2-20 threaded end allows secure fastening and controlled extraction using a standard nut. This style of taper pin is used to fix the position of machine components on shafts or through aligned holes, providing repeatable, self-locking alignment. It meets AN386 standards and is suited for industrial, aerospace-adjacent, and mechanical assembly applications where corrosion resistance and dimensional precision are required.

Threaded taper pins in this size range are commonly installed in mechanical assemblies where a shaft-to-hub connection, lever arm, or component alignment point must be secured and periodically disassembled. The passivated stainless steel construction makes this pin appropriate for wet, washdown, or mildly corrosive environments. Machinists, millwrights, and maintenance technicians working on industrial machinery, pumps, conveyors, and similar equipment are the primary installers of this fastener type.

Key Features

• Size 9 taper profile with a 0.589-inch large end diameter for precise hole fit
• 3-inch pin length suitable for moderate material stack thicknesses
• 1/2-20 threaded end enables controlled installation and extraction
• Grade 303, 18-8 stainless steel provides corrosion resistance in demanding environments
• Passivated finish removes surface contaminants and enhances corrosion protection
• Meets AN386 standard for dimensional and material conformance

Compatibility

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

Installation Notes

Taper pins are installed by machinists or maintenance technicians using a pin driver or press into a reamed tapered hole that matches the pin taper ratio. Ensure the mating assembly is fully de-energized and locked out before pin installation or removal. The threaded end should engage a standard nut to drive the pin fully into the bore and to extract it without damage to the bore surface. Do not force an oversized pin into an undersized hole, as this can crack the hub or distort the shaft.
