Value Collection MSC67704361X Threaded Taper Pin Size 6

Product Description

The VALUE COLLECTION MSC67704361X is a Size 6 threaded taper pin machined from C-12L14 free-machining steel with an uncoated finish. The pin features a 5/16-24 unified fine thread on the threaded end, a large end diameter of 0.339 inches, and a neck diameter of 0.253 inches. Overall pin length is 2.25 inches. The tapered body conforms to AN386 standards, making it a recognized hardware component for mechanical assemblies, jigs, fixtures, and structural connections where a positively retained, removable pin is required. Machinists, millwrights, and maintenance technicians install these pins when alignment and repeatability under load are priorities.

Threaded taper pins are used in light to medium industrial applications where the nut-retained design prevents the pin from backing out under vibration or dynamic loading. Typical install scenarios include shaft-to-hub connections, tooling fixtures, and hinge assemblies in both OEM manufacturing and MRO maintenance environments. The C-12L14 material grade offers good machinability and consistent dimensional tolerance, which is critical in close-fit bores. This pin is sold individually and is suitable for repair, replacement, or initial assembly work across a wide range of mechanical systems.

Key Features

• AN386 standard compliance for recognized dimensional and tolerance conformance

• Large end diameter of 0.339 inches with a maximum diameter tolerance of 0.0013 inches
• C-12L14 free-machining steel for consistent bore fit and machinability
• Uncoated finish suitable for environments where additional coatings or treatments will be applied
• 2.25 inch pin length fits Size 6 taper pin bores per standard sizing

Compatibility

Designed as an OEM-style replacement or new-installation threaded taper pin for Size 6 taper pin bores conforming to AN386 dimensional standards in mechanical assemblies and fixtures.

Installation Notes

Threaded taper pins are installed by machinists or maintenance technicians using a pin driver or press to seat the tapered body fully into a reamed taper hole before threading the nut. Always ensure the mating bore is reamed to the correct taper and size before installation to avoid galling or improper seating. Disengage or de-energize any machinery and relieve all mechanical load on the assembly before removing or installing the pin. Do not force an oversized pin into an undersized bore.
