Value Collection MSC67707166X Taper Pin Size 9 1/2-20

Product Description

The VALUE COLLECTION MSC67707166X is a Size 9 externally threaded taper pin manufactured from 303 grade 18-8 stainless steel with a passivated finish. The pin measures 6 inches in length with a large end diameter of 0.589 inches and a neck diameter of 0.43 inches. A 1/2-20 threaded end allows for extraction using a standard nut, simplifying removal from blind or tight assemblies. Passivation improves corrosion resistance by removing surface contaminants and promoting a stable oxide layer. This pin is suited for mechanical assembly applications where alignment, positioning, or load transfer between components is required. Machinists, millwrights, and maintenance technicians are the typical installers.

This taper pin is used in industrial and mechanical assemblies where a precise, self-locking fit between mating components is needed. The tapered profile locks under load without supplemental fasteners at the mating interface, making it a reliable choice for shaft-to-hub connections, pivot points, and alignment fixtures. The threaded end accommodates a nut for controlled extraction without damaging the parent material. Conformance to AN386 standards ensures dimensional consistency for drop-in replacement or new-build applications in aerospace-adjacent and general industrial environments.

Key Features

• Size 9 taper with 0.589-inch large end diameter and 0.43-inch neck diameter
• 6-inch pin length suits deeper assemblies and shaft connections
• 1/2-20 threaded end enables controlled extraction using a standard nut
• 303 grade 18-8 stainless steel construction for corrosion resistance in wet or industrial environments
• Passivated finish reduces surface oxidation and extends service life
• Meets AN386 standards for dimensional and material consistency

Compatibility

Designed as a standard AN386 Size 9 threaded taper pin for use in industrial machinery, mechanical assemblies, and aerospace-adjacent applications requiring a 1/2-20 threaded extraction interface.

Installation Notes

Installation and removal should be performed by a qualified machinist or maintenance technician. De-energize all equipment and relieve any load from the assembly before driving or extracting the pin. Use a properly sized taper pin reamer to prepare the hole to the correct taper before installation. When extracting, thread a 1/2-20 nut onto the pin and draw it out evenly to avoid galling or distortion of the parent bore.
