Value Collection MSC67703561X Threaded Taper Pin Size 3

Product Description

The VALUE COLLECTION MSC67703561X is a Size 3 externally threaded taper pin designed for mechanical assemblies requiring a secure, removable connection between mating components. Made from C-12L14 steel in an uncoated finish, this pin meets AN386 standards and features a large end diameter of 0.217 inches and a neck diameter of 0.144 inches. The 10-32 threaded end accepts a nut to lock the pin in place and prevent loosening under vibration or load. Machinists, millwrights, and maintenance technicians install threaded taper pins in shafts, hubs, levers, and linkages across industrial and mechanical equipment applications.

This threaded taper pin is suited for use in precision mechanical assemblies where a standard taper pin requires positive retention. Typical applications include securing collars, gears, and handwheels to shafts, as well as alignment and locating functions in fabricated weldments and machined assemblies. The C-12L14 free-machining steel construction supports reliable installation in both light industrial and maintenance repair operations. This pin ships individually and is subject to a minimum order quantity of 5 units.

Key Features

• AN386 standard compliance for consistent taper geometry and interchangeability
• 10-32 threaded end allows nut retention to prevent pin walkout under vibration
• C-12L14 free-machining steel provides good machinability and consistent dimensional tolerances
• Large end diameter of 0.217 inches with a maximum diameter tolerance of 0.0013 inches
• Uncoated finish suitable for general industrial use or post-installation treatment
• Size 3 taper pin designation for straightforward cross-referencing and replacement

Compatibility

Designed as a standard AN386 Size 3 threaded taper pin replacement for mechanical assemblies requiring a 10-32 threaded taper pin with a 0.217-inch large end diameter.

Installation Notes

Threaded taper pins are typically installed by machinists or millwrights using a pin driver or arbor press to seat the pin fully into the reamed taper hole before threading the retaining nut. Always de-energize and lock out the equipment before servicing pinned connections. The mating hole should be reamed to the correct AN386 taper to ensure proper fit and full contact along the pin shank. Do not force an oversized pin into an underreamed hole, as this can damage the workpiece or cause improper seating.
