Value Collection MSC67704247X Threaded Taper Pin Size 6

Product Description

The VALUE COLLECTION MSC67704247X is a Size 6 threaded taper pin machined from C-12L14 steel in an uncoated finish. Taper pins are precision alignment and locking fasteners used to secure hubs, collars, gears, and other components to shafts in mechanical assemblies. This pin measures 0.339 inches at the large end diameter and 1.5 inches in pin length, with a 5/16-24 threaded end that accepts a nut for positive retention. Manufactured to AN386 standards, it is suited for applications requiring repeatable, accurate positioning and reliable axial locking in moderate-load service.

Threaded taper pins are common in industrial machinery, pump assemblies, conveyor drives, and mechanical power-transmission equipment where standard taper pins would risk loosening under vibration or cyclic loading. The threaded end allows controlled extraction and reinstallation during routine maintenance without damaging the mating hole. This pin is appropriate for use by millwrights, machinists, and maintenance mechanics working on shaft-mounted components in both original equipment and field-repair contexts.

Key Features

• Size 6 taper pin with 0.339 inch large end diameter for positive shaft-to-hub alignment
• 5/16-24 threaded end allows nut retention and controlled extraction
• C-12L14 steel construction provides good machinability and moderate strength
• Uncoated finish suitable for standard indoor mechanical environments
• Manufactured to AN386 standards for dimensional consistency
• 1.5 inch pin length accommodates typical shaft collar and hub widths in this size class

Compatibility

Designed as an OEM-style replacement or standard service fastener for mechanical assemblies requiring a Size 6 AN386 threaded taper pin with a 5/16-24 thread form.

Installation Notes

Threaded taper pins are installed by a machinist or maintenance mechanic using a properly sized taper pin reamer to prepare or verify the hole before driving. Ensure the mating shaft and hub bore are clean, free of burrs, and correctly aligned before installation. Always use the appropriate pin driver or press to seat the pin without deforming the threaded end, and torque the retaining nut to the assembly specification. Removal is accomplished by backing off the nut and using a pin punch or extractor against the small end.
