Value Collection MSC67704684X Threaded Taper Pin Size 7

Product Description

The VALUE COLLECTION MSC67704684X is a Size 7 externally threaded taper pin manufactured from C-12L14 steel in an uncoated finish. The pin measures 3 inches in length with a large-end diameter of 0.407 inches and features a 3/8-24 threaded end for secure retention with a nut. Taper pins are precision fasteners used to align or lock components on shafts, in hubs, and across structural assemblies. Maximum diameter tolerance is held to 0.0013 inches, meeting AN386 standards for dimensional consistency. This part is suited for machinists, maintenance technicians, and assembly professionals working in industrial or MRO environments.

Threaded taper pins of this size are commonly used in mechanical assemblies where positive locking is required and the pin must be retained against vibration or axial movement. The 3/8-24 threaded end accepts a standard nut, making the pin removable without damage to the hole. Typical applications include shaft-to-hub connections, linkage assemblies, and fixture alignment in light to medium industrial settings. The uncoated steel finish is appropriate for indoor or protected environments where corrosion exposure is limited.

Key Features

• 3/8-24 threaded end for nut retention and secure locking
• 3 inch pin length for medium-depth through-hole applications
• C-12L14 free-machining steel construction for consistent dimensional accuracy
• Maximum diameter tolerance of 0.0013 inches per AN386 standard
• Uncoated finish suitable for protected indoor assemblies

Compatibility

Designed as an AN386-standard Size 7 threaded taper pin for use in mechanical assemblies requiring a 0.407 inch large-end taper hole and a 3/8-24 threaded retention nut.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a reamed taper hole sized to match the pin taper. Disengage and lock out all power to rotating or actuated equipment before inserting or removing the pin. Drive the pin in from the small-end side and thread the retaining nut onto the 3/8-24 end before applying final seating force. Do not force an oversized pin into an undersized hole, as this can damage the bore or split the hub.
