Value Collection MSC67704486X Threaded Taper Pin Size 6

Product Description

The VALUE COLLECTION MSC67704486X is a Size 6 threaded taper pin machined from C-12L14 steel with an uncoated finish. It is designed to secure components on shafts or in assemblies where a precise, removable fastening method is required. The pin measures 4 inches in length with a large-end diameter of 0.339 inches and a neck diameter of 0.253 inches. The 5/16-24 threaded end allows a nut to be driven against the assembly for positive retention and controlled removal. Maximum diameter tolerance is held to 0.0013 inches, supporting accurate alignment in mechanical assemblies. This pin meets AN386 standards and is suited for use by machinists, millwrights, and maintenance technicians.

Threaded taper pins are commonly used in industrial machinery, tooling fixtures, and mechanical assemblies where axial alignment and positive locking are necessary. The threaded end simplifies removal in blind-hole or tight-clearance applications where a standard taper pin drift punch cannot be used from the small end. This pin is appropriate for both original equipment assembly and field maintenance work across a wide range of industrial and manufacturing environments.

Key Features

• Size 6 taper with 0.339-inch large-end diameter for precise shaft and hub alignment
• 4-inch pin length accommodates medium-depth assemblies
• 5/16-24 threaded end enables controlled removal with a standard nut and wrench
• C-12L14 free-machining steel provides consistent dimensional accuracy
• Maximum diameter tolerance of 0.0013 inches supports close-fit applications
• Meets AN386 standards for threaded taper pin geometry and dimensions

Compatibility

Designed as a standard AN386 threaded taper pin replacement for mechanical assemblies requiring a Size 6 taper pin with a 5/16-24 threaded end.

Installation Notes

Installation and removal should be performed by a qualified machinist or maintenance technician. Always de-energize and lock out the equipment before servicing any pinned assembly. Drive the pin from the small end toward the large end for seating, and use the threaded end with an appropriate nut to extract the pin during removal. Verify hole taper and alignment before final seating to prevent galling or distortion of mating components.
