Value Collection MSC67703603X Threaded Taper Pin Size 3

Product Description

The VALUE COLLECTION MSC67703603X is a Size 3 threaded taper pin machined from C-12L14 free-machining steel with an uncoated finish. It features a 0.217-inch large-end diameter, a 1.5-inch pin length, and a 10-32 threaded end for secure fastening in precision assemblies. Taper pins are used to lock hubs, collars, and levers onto shafts or to align mating components in mechanical assemblies. The C-12L14 steel grade provides good machinability and consistent dimensional accuracy, making it a reliable choice for production and maintenance applications. Installation and removal are straightforward with standard pin tooling.

This threaded taper pin is suited for light-to-medium duty mechanical assemblies where a removable, self-locking pin connection is required. The 10-32 threaded end allows a nut to be applied to prevent the pin from backing out under vibration or dynamic loading. Typical applications include shaft-to-hub connections, fixture alignment, and machine component retention in manufacturing, maintenance, and industrial repair environments. Machinists, maintenance technicians, and mechanical assemblers are the primary installers of this hardware.

Key Features

• Size 3 taper profile with 0.217-inch large-end diameter for precise shaft and hub alignment
• 10-32 threaded end allows nut retention to resist vibration-induced backing out
• C-12L14 free-machining steel grade for consistent dimensional tolerances
• Maximum diameter tolerance of 0.0013 inches for close-fit applications
• Meets AN386 standard for threaded taper pins
• Uncoated finish suitable for assemblies where coating buildup on tapered surfaces must be avoided

Compatibility

Designed as a standard Size 3 threaded taper pin conforming to AN386 specifications, suitable for use in mechanical assemblies requiring a 10-32 threaded taper pin with a 0.217-inch large-end diameter.

Installation Notes

Taper pins are installed by driving them into a reamed taper hole using a pin punch or hammer; the hole must be reamed to the correct taper before installation. Ensure mating components are properly aligned and secured before driving the pin. Apply a nut to the 10-32 threaded end and torque to the assembly specification to prevent pin migration. Disassembly is performed by driving the pin out from the small end using a taper pin extractor or punch.
