Value Collection MSC67705244X Threaded Taper Pin Size 8

Product Description

The VALUE COLLECTION MSC67705244X is a Size 8 threaded taper pin machined from C-12L14 free-machining steel. The pin measures 4 inches in length with a large-end diameter of 0.49 inches and features a 7/16-20 threaded end for positive retention and easy extraction. Manufactured to AN386 standards, this pin is supplied in an uncoated finish. It is used to lock components to shafts and align mating parts in mechanical assemblies across industrial, agricultural, and maintenance applications. Machinists, maintenance technicians, and millwrights are the primary installers.

This taper pin is suited for general industrial assembly and MRO applications where a reliable, removable fastener is needed to secure hubs, collars, gears, and levers to shafts. The threaded end allows a nut or extractor to be used for clean removal without driving the pin through the bore, making it practical in tight assemblies and field service situations. It is appropriate for both original equipment assembly and replacement in existing taper-pin applications conforming to AN386.

Key Features

• Threaded 7/16-20 end allows positive extraction without a pin punch
• C-12L14 free-machining steel provides consistent dimensional accuracy and machinability
• Manufactured to AN386 standard for dimensional interchangeability
• Large-end diameter of 0.49 inches with a maximum diameter tolerance of 0.0013 inches
• Uncoated finish suitable for further treatment or use in standard indoor mechanical environments

Compatibility

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

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a reamed taper bore matched to the pin taper. Ensure the mating bore is clean and free of burrs before driving the pin to its seated position. Use the threaded end with an appropriate nut or slide hammer extractor for removal rather than reverse-driving, which can damage the bore. De-energize or lock out any rotating equipment before servicing taper pin connections in accordance with applicable OSHA lockout/tagout procedures.
