200383 - Miller .250-20 x 0.50 Grade 8 Socket Head Cap Screw (Pack of 50)

Genuine Miller OEM Grade 8 Hardware

The Miller 200383 is a premium replacement screw designed specifically for the rigorous demands of industrial welding equipment. Sold in a convenient package of 50, this fastener features a .250-20 (1/4-20) thread pitch and a 0.50-inch length, making it a common and essential component for securing panels, internal assemblies, and structural elements within Miller power sources. As a Genuine Miller Electric OEM part, it guarantees the precise fit and material quality required to maintain the integrity of your machine.

Superior Strength and Durability

Unlike standard hardware store fasteners, this screw is manufactured to Grade 8 specifications. Grade 8 steel is heat-treated to provide exceptional tensile strength and hardness, making it significantly stronger than Grade 5 or unrated commercial screws. In the context of welding machinery, which is often subjected to constant vibration, thermal expansion, and contraction, using high-grade hardware is critical. The Grade 8 rating ensures that the screw will not stretch, shear, or loosen easily under stress, preventing rattles, loose connections, or mechanical failures that could interrupt production.

Precision Design for Maintenance

The screw features a Socket Head Cap design, driven by a hex key (Allen wrench). This head style is preferred in industrial machinery because it allows for higher torque application compared to Phillips or slotted heads, ensuring a tight and secure fit. The compact cylindrical head also fits into recessed counterbores often found on equipment casings, providing a flush and snag-free surface. The "Plain" finish indicates that the screw relies on the high-quality steel alloy for performance without a thick zinc or galvanized coating that could interfere with precision thread tolerances or electrical grounding paths where applicable.

Bulk Packaging for Efficiency

Maintenance professionals and repair shops understand the frustration of halting a repair due to a missing bolt. This product is supplied as a package of 50 units, providing an ample supply for complete machine overhauls or stocking your parts bin for future needs. Whether you are replacing stripped screws during routine maintenance or reassembling a machine after a major repair, having the correct OEM specification hardware on hand ensures the job is done right the first time.
