Miller 6-32 x 0.37 Hex Washer Head Grounding Screw

Miller 229314 Hex Washer Head Screw with Ground Ring

The Miller 229314 is a specialized machine screw engineered for use in Miller welding equipment. As a genuine Miller Electric component, it meets the strict manufacturing tolerances required for the assembly and repair of professional welding machines. This fastener is identified by its #6-32 thread pitch and 0.37-inch length, making it a common hardware piece for securing internal components, panels, and electrical connections within various Miller models.

Technical Design and Function
This screw is manufactured from plated steel, offering necessary strength and corrosion resistance for industrial environments. The head style is a Hex Washer Head (Hex Whd), which allows for high-torque tightening using a socket or nut driver, minimizing the risk of cam-out associated with Phillips or slotted drives. The integrated washer face eliminates the need for a separate flat washer in many applications.

Electrical Grounding Capability
A key specification of the Miller 229314 is the "W/SPL GNDRNG" designation, indicating the presence of a split ground ring. In welding machines, proper grounding of internal components is critical for safety and noise suppression. The split ring acts as a lock washer that cuts through surface oxides or paint to establish a solid electrical bond between the component and the chassis. This ensures that the screw performs a dual function: mechanical retention and electrical continuity. Technicians repairing Miller equipment should always replace these screws with the exact OEM part to maintain the electrical safety integrity of the machine.
