Value Collection MSC67705004X Threaded Taper Pin Size 8

Product Description

The VALUE COLLECTION MSC67705004X is a Size 8 threaded taper pin machined from C-12L14 steel with a natural uncoated finish. The large end diameter measures 0.49 inches and the pin length is 2 inches. A 7/16-20 threaded end allows a nut to be applied for secure retention, making removal and reinstallation straightforward in service environments. This taper pin is designed for use in mechanical assemblies where a precise, self-locking fit between a shaft and hub or similar mating components is required. Machinists, millwrights, and maintenance technicians working on industrial and light mechanical assemblies are the primary installers.

Threaded taper pins of this size are commonly used in general mechanical assemblies, machine tool applications, and maintenance-repair-overhaul work where positive alignment and repeatable positioning are critical. The Size 8 designation and 7/16-20 thread make this pin suitable for moderate-load applications in both production and field-service settings. It is sold individually and is appropriate for bench-level assembly work or as a direct replacement in existing taper pin locations.

Key Features

• Size 8 taper pin with 0.49 inch large end diameter and 2 inch pin length
• C-12L14 steel construction for good machinability and consistent tolerances
• 7/16-20 threaded end for nut retention and controlled extraction
• Uncoated finish for direct use or field modification
• Maximum diameter tolerance of 0.0013 inches for precise mating fits
• Meets AN386 standard

Compatibility

Designed as a standard Size 8 threaded taper pin conforming to AN386 for use in mechanical shaft-to-hub and alignment applications requiring a 7/16-20 threaded retention nut.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a pin driver or press and the appropriate size taper reamer to ensure the mating hole is properly sized before driving. Always secure or de-energize any rotating or loaded equipment before working on shaft and hub assemblies. Apply the retention nut to the threaded end after seating the pin to prevent backing out under vibration. For extraction, thread a nut onto the pin and drive against it to avoid damaging the threaded section.
