Value Collection MSC67705327X Threaded Taper Pin Size 8

Product Description

The VALUE COLLECTION MSC67705327X is a Size 8 threaded taper pin manufactured from C-12L14 leaded steel and finished uncoated. The pin measures 6 inches in total length with a large end diameter of 0.49 inches and a neck diameter of 0.368 inches. A 7/16-20 threaded end allows a nut to be applied for secure retention and controlled extraction. Maximum diameter tolerance is held to 0.0013 inches, keeping the fit consistent for precision alignment applications. Machinists, millwrights, and maintenance technicians use this pin to lock hubs, gears, collars, and other machine components onto shafts where alignment and positive retention are critical.

This threaded taper pin is suited for industrial machinery, power transmission assemblies, and general mechanical fabrication where AN386-compliant taper pin fasteners are specified. The threaded design gives the installer a mechanical advantage for driving the pin to full seat and for removing it without damaging the component. C-12L14 steel provides good machinability and adequate shear strength for moderate-load applications in both production and maintenance environments.

Key Features

• Threaded end (7/16-20) enables nut-assisted seating and controlled removal
• C-12L14 leaded steel construction for consistent machinability
• Uncoated finish suits applications where additional coating is not required or will be applied in the field
• Meets AN386 standard for taper pin dimensions and tolerances
• Maximum diameter tolerance of 0.0013 inches for predictable fit in reamed holes
• Size 8 taper with 6-inch pin length covers a broad range of shaft and hub thicknesses

Compatibility

Designed as an AN386-compliant Size 8 threaded taper pin for use in standard taper-reamed holes sized for a Size 8 taper pin in industrial machinery and power transmission assemblies.

Installation Notes

Installation is typically performed by machinists or maintenance millwrights using a taper pin reamer to prepare the hole to the correct taper before driving the pin. Ensure the mating assembly is secured and free of load before driving or removing the pin. Apply a nut to the threaded end before driving to protect threads, and use it to pull the pin during removal rather than driving it out from the small end to prevent bore damage. Follow applicable machine safety lockout and tagout procedures before servicing any assembly.
