268960 - Miller 1/4-20 x 7/8 Hex Head Grade 8 Locking Screw

Genuine Miller OEM Replacement Hardware

The Miller 268960 is a specialized hex head screw designed to meet the rigorous demands of industrial welding equipment. As a genuine Original Equipment Manufacturer (OEM) part, this fastener is engineered to the exact specifications required by Miller Electric for their power sources and wire feeders. Using non-OEM hardware in precision equipment can often lead to fitment issues or premature failure, but the 268960 ensures a perfect match for the intended assembly points within your machine.

Grade 8 Strength and Durability

This screw is manufactured from Grade 8 steel, which is significantly stronger than standard Grade 2 or Grade 5 hardware. Grade 8 fasteners are heat-treated to provide high tensile strength, making them suitable for high-stress applications where structural integrity is paramount. Whether securing a heavy transformer, a chassis panel, or a drive motor, this screw provides the clamping force necessary to keep components rigidly in place during operation.

Vibration Resistance and Corrosion Protection

Welding machines generate significant vibration during operation. To combat this, the Miller 268960 features an integrated locking patch on the threads. This patch creates interference between the screw and the mating thread, preventing the fastener from backing out over time due to vibration. Additionally, the zinc plating offers a layer of protection against oxidation and rust, extending the life of the fastener even in humid or shop environments. This combination of strength, security, and durability makes it the ideal choice for maintaining the reliability of your Miller equipment.
