108943 - Miller 108943 Screw 1/4-20 x 1.50 Hex Washer Head Grade 5

Genuine Miller Replacement Hardware

When maintaining or repairing your Miller welding equipment, using the correct hardware is essential for ensuring the longevity and safety of the machine. The Miller 108943 Screw is a genuine OEM replacement part designed specifically for Miller power sources and industrial equipment. This fastener features a standard .250-20 (1/4-20) thread pitch and a length of 1.50 inches, making it a common component in various chassis assemblies and panel securement points.

Constructed to Grade 5 specifications, this screw offers superior tensile strength compared to standard hardware store fasteners. This strength is critical in welding environments where equipment is often subjected to vibration, thermal expansion, and rough handling. The screw is designed with a Hex Washer Head (HexWHD), which features an integral washer face with a diameter of 0.61 inches. This design eliminates the need for a separate washer, simplifying installation and ensuring a broad bearing surface to distribute clamping load effectively without damaging the underlying surface.

The screw comes with a plated finish (PLD) to provide corrosion resistance, protecting the fastener from rust and oxidation that can occur in humid or industrial shop environments. Whether you are replacing a lost screw during routine maintenance or performing a repair on a specific Miller welder model, relying on the Miller 108943 ensures that your equipment remains assembled to factory specifications. Always verify fitment with your machine's parts manual before ordering.
