Value Collection MSC67705087X Threaded Taper Pin Size 8

Product Description

The VALUE COLLECTION MSC67705087X is a Size 8 threaded taper pin machined from C-12L14 steel in an uncoated finish. Taper pins are precision fastening components used to lock hubs, collars, and machine parts onto shafts, providing a secure, self-locking connection that resists axial and rotational movement. This pin features a 7/16-20 threaded small end for nut retention, a large end diameter of 0.49 inches, and a pin length of 2-1/2 inches. It conforms to AN386 standards and is intended for use by machinists, millwrights, and maintenance technicians working on mechanical assemblies requiring reliable pinned connections.

This threaded taper pin is suited for general industrial and mechanical maintenance applications where a positive, removable shaft-to-hub connection is required. The C-12L14 free-machining steel construction makes it a practical choice for light to medium-duty machinery, tooling fixtures, and equipment assemblies. The 7/16-20 threaded end allows a nut to be driven against the assembly for secure retention and also aids in extraction during disassembly. Typical installation environments include manufacturing facilities, machine shops, and field maintenance settings.

Key Features

• Size 8 taper pin with 0.49 inch large end diameter for precise shaft-to-hub fitment
• 7/16-20 threaded small end allows nut-secured retention and controlled extraction
• C-12L14 free-machining steel construction balances machinability with adequate strength
• Uncoated finish suitable for standard indoor mechanical applications
• Conforms to AN386 standards for dimensional consistency
• Maximum diameter tolerance of 0.0013 inches for repeatable, accurate fit

Compatibility

Designed as a standard AN386-compliant Size 8 threaded taper pin for use in mechanical assemblies requiring a 0.49 inch large end diameter taper pin with a 7/16-20 threaded end.

Installation Notes

Threaded taper pins are typically installed and removed by machinists or maintenance technicians using a pin driver, hammer, and appropriate wrenches. Always de-energize and lock out equipment before servicing any pinned mechanical assembly. Drive the pin into a reamed taper hole from the large end and thread the nut onto the small end to secure. Never force an oversized pin into a taper bore, as this can damage the bore or split the hub.
