Value Collection MSC67704924X Threaded Taper Pin Size 8

Product Description

The VALUE COLLECTION MSC67704924X is a Size 8 externally threaded taper pin used to secure components on shafts, hubs, and assemblies where a removable, positive-locking fastener is required. Manufactured from C-12L14 steel in an uncoated finish, this pin has a large end diameter of 0.49 inches and a neck diameter of 0.368 inches. The 7/16-20 threaded end accepts a standard nut to retain the pin under load and allow controlled removal. At 1.5 inches in pin length, it suits medium-duty mechanical assemblies. Machinists, millwrights, and maintenance technicians install this type of pin when alignment or torque transfer must be maintained and the joint needs to be periodically disassembled.

Threaded taper pins are commonly used in industrial machinery, agricultural equipment, power transmission assemblies, and precision fixtures. The Size 8 designation and 7/16-20 thread make this pin appropriate for mid-range shaft and hub diameters in both light industrial and OEM production environments. The AN386 standard designation indicates conformance to aerospace and industrial dimensional requirements, making it suitable for applications where controlled fit and repeatability are critical.

Key Features

• C-12L14 steel construction for good machinability and consistent dimensional tolerances
• Large end diameter of 0.49 inches with a maximum diameter tolerance of 0.0013 inches
• Neck diameter of 0.368 inches for precise hole fitment
• 7/16-20 threaded end allows nut retention and controlled disassembly
• Meets AN386 standard for dimensional conformance
• Uncoated finish suitable for use as-received or with field-applied lubrication or coating

Compatibility

Designed as a Size 8 threaded taper pin conforming to AN386 dimensional standards, suitable for use in any application requiring a 7/16-20 threaded taper pin with a 0.49-inch large end diameter and 1.5-inch pin length.

Installation Notes

Installation is typically performed by machinists or millwrights using a reamed tapered hole sized to match the pin taper. The assembly should be depowered and, where applicable, locked out and tagged out before pin installation or removal. Use a properly sized taper reamer to prepare the hole before driving the pin to avoid galling or dimensional damage. The threaded end nut should be tightened to retain the pin but should not be used to draw the pin into an undersized hole.
