Value Collection MSC67703645X Taper Pin Size 3 Steel 10-32

Product Description

The VALUE COLLECTION MSC67703645X is a Size 3 threaded taper pin machined from C-12L14 steel in an uncoated finish. The pin measures 2 inches in length with a large end diameter of 0.217 inches and features a 10-32 threaded end for secure extraction using a standard threaded puller. Taper pins of this type are used to locate and lock components on shafts, hubs, and assemblies where precise, repeatable alignment is required. This pin conforms to AN386 standards and carries a maximum diameter tolerance of 0.0013 inches, making it appropriate for close-tolerance mechanical work in industrial and maintenance applications.

This taper pin is suited for general industrial, aerospace-maintenance, and machine-shop use where AN386-compliant fasteners are specified. It is commonly installed in shaft-to-hub connections, gear assemblies, and fixture locating applications. The 10-32 threaded end allows controlled removal without damaging the mating bore, which is especially useful in assemblies that require periodic disassembly. Machinists, millwrights, and maintenance technicians working on rotating machinery or precision fixtures are the primary installers of this type of hardware.

Key Features

• 10-32 threaded end for puller-assisted extraction
• C-12L14 steel construction for consistent machining and strength
• Uncoated finish suitable for use as-is or with applied corrosion protection
• Conforms to AN386 standards with a maximum diameter tolerance of 0.0013 inches

Compatibility

Designed as an AN386-compliant Size 3 threaded taper pin for use in any shaft, hub, or mechanical assembly that accepts a standard Size 3 taper pin bore with a 10-32 threaded extraction point.

Installation Notes

Taper pins are typically installed by machinists or millwrights using a pin driver or press, with the mating bore reamed to the correct taper before installation. Ensure the assembly is de-energized and secured before driving or extracting the pin. The 10-32 threaded end requires a matching puller for controlled removal — do not drive the pin out from the threaded end. Follow applicable facility safety and machinery lockout-tagout procedures during installation and removal.
