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

Miller 108943 Hex Washer Head Screw - Grade 5

The Miller 108943 is a high-quality replacement screw engineered to meet the rigorous demands of industrial welding equipment. As a genuine Miller Electric component, this screw guarantees precise fitment and material compatibility with your welding machine. It is defined by its specific dimensions: a 1/4-20 UNC thread and a 1.50-inch length, commonly used to secure internal components, outer shells, and structural elements of Miller power sources.

Key Technical Features:

• Head Design: The Hex Washer Head style incorporates a built-in washer with a 0.61-inch diameter. This provides excellent torque retention and prevents the screw head from embedding into softer sheet metal components.
• Material Strength: Rated as Grade 5, this fastener is manufactured from medium carbon steel that has been quenched and tempered. This ensures it can withstand significant stress and vibration without shearing or stretching, a common failure point for lower-grade replacements.
• Corrosion Protection: The plated finish ensures the screw remains free of corrosion, facilitating easier removal in the future if maintenance is required.

Using non-OEM hardware can often lead to mismatched thread pitches or insufficient clamping force. The Miller 108943 eliminates guesswork. It is sold individually, allowing you to purchase exactly the quantity needed for your repair. Please consult your welder's service manual or parts breakdown to confirm this part number corresponds to the specific location on your machine requiring replacement.
