Value Collection MSC67705566X Threaded Taper Pin Size 9

Product Description

The VALUE COLLECTION MSC67705566X is a Size 9 externally threaded taper pin manufactured from C-12L14 steel with an uncoated finish. The pin features a 0.589-inch large-end diameter, a 4.5-inch pin length, and a 1/2-20 threaded end that accepts a standard nut for secure retention in tapered holes. Taper pins are used to lock hubs, collars, and mechanical assemblies onto shafts, preventing rotational or axial movement under load. This pin meets AN386 standards and is suited for maintenance, repair, and original-equipment assembly work performed by machinists, millwrights, and maintenance technicians.

This threaded taper pin is used in shaft-to-hub connections on mechanical power transmission assemblies including pumps, gearboxes, conveyor systems, and general industrial machinery. The 1/2-20 threaded end allows a nut to be driven against the assembly face, making extraction and retention more positive than a standard smooth taper pin. Typical applications are found in both light industrial and heavy-duty maintenance environments where a reliable, removable fastener is required to index or lock rotating components.

Key Features

• Size 9 taper pin with 0.589-inch large-end diameter for precise shaft and hub alignment
• 4.5-inch pin length suits deeper hub assemblies and heavier shaft sections
• 1/2-20 threaded end accepts a standard nut for positive retention and easier extraction
• C-12L14 free-machining steel construction provides good strength and machinability
• Uncoated finish — suitable for applications where a coating or plating is applied post-installation or not required
• Meets AN386 standard for threaded taper pins

Compatibility

Designed as a standard AN386-compliant Size 9 threaded taper pin for use in tapered holes reamed to Size 9 specifications on shaft and hub assemblies across general industrial and mechanical power transmission applications.

Installation Notes

Installation is typically performed by a machinist or maintenance technician using a taper pin reamer to prepare a properly sized tapered hole before driving the pin. Always de-energize and lock out the equipment before servicing any shaft or hub assembly. The threaded end should be fitted with an appropriate nut and washer and tightened to draw the pin fully into the tapered hole — do not hammer the threaded section. Follow applicable machinery safety standards and manufacturer torque guidelines for the specific assembly being serviced.
