604804 - Miller 604804 Hex Washer Head Sheet Metal Screw #8-15 x 0.37

Genuine Miller Replacement Hardware

The Miller 604804 Screw is a specialized hardware component designed to meet the exact specifications of Miller Electric welding equipment. As a genuine OEM part, this screw ensures that maintenance and repairs maintain the original factory standards of your machinery. The fastener is identified as a 008-15X .37 HexwHD-Pln Stl Pld Sht Met A, indicating a robust design tailored for industrial environments.

Technically, this is a #8-15 thread size sheet metal screw with a length of 0.37 inches. It features a Hex Washer Head (HexwHD), which combines a hexagonal drive for high-torque installation with an integrated washer face. This design is critical for sheet metal applications as the washer face distributes the clamping force over a larger area, reducing the risk of crushing the material or pulling the screw head through the panel. The "Type A" designation typically refers to a coarse-thread screw with a sharp point, optimized for forming mating threads in thin metal sheets, resin-impregnated plywood, or asbestos compositions without pre-tapping.

Constructed from plain steel with a plated finish, this screw offers essential durability and corrosion resistance required for workshop environments. Whether you are replacing a lost fastener during routine maintenance or reassembling a machine after internal repairs, using the correct specification screw is vital to prevent thread stripping or loose panels. This part is commonly used to secure outer casings, access panels, and internal brackets within various Miller power sources and wire feeders.

By choosing the authentic Miller 604804, you avoid the guesswork associated with matching thread pitches and head styles at a hardware store. This ensures a hassle-free installation and a secure fit that withstands the vibration and thermal cycling common in welding operations.
