The Miller 281490 is a specialized machine screw designed for the assembly and maintenance of Miller welding equipment. This hardware component features a .250-20 (1/4-20) UNC thread pitch and a length of 0.75 inches, making it a standard fastener size used across various industrial applications. The screw is manufactured from durable steel, providing the necessary tensile strength to withstand the vibration and thermal cycles often associated with welding environments.
A key feature of this fastener is its Truss Head design. Truss heads are characterized by a low-profile dome and a wider bearing surface compared to standard pan or round heads. This wider surface area distributes the clamping force over a larger area, which is particularly beneficial when fastening sheet metal panels or components where minimizing surface deformation is critical. The low profile also reduces snag points on the exterior of machine casings.
The drive system utilized is a Socket drive, commonly referred to as a Hex or Allen drive. This drive style allows for the application of higher torque values compared to Phillips or slotted drives, as the tool is fully enclosed within the fastener head, virtually eliminating the risk of "cam-out." This ensures that the screw can be tightened securely during assembly and removed easily during maintenance without damaging the drive recess. This product is supplied as a package of 4, ensuring you have the necessary quantity for repairs or replacements.
