97192125 - Arcair K4000 Replacement Head Screw 1/4-20 x 7/8 Plated

Precise Replacement Hardware for Arcair K4000 Systems

The Arcair 97-192-125 Head Screw is a critical replacement component engineered specifically for the K4000 Angle-Arc manual gouging torch. In the demanding field of air carbon arc gouging, every component of the torch assembly plays a vital role in ensuring safety, conductivity, and structural integrity. This specific screw is designed to secure the head assembly components, often holding the insulators and lever mechanisms in place against the main body of the torch. Manufactured to precise OEM specifications, it features a 1/4-20 UNC thread pitch and a 7/8-inch length, ensuring it seats perfectly without stripping threads or bottoming out prematurely.

Constructed with a plated finish, this Pan Head Machine Screw (PHMS) is built to withstand the rigorous environment typical of metal fabrication and maintenance operations. The plating provides essential resistance against corrosion and oxidation, which are common issues in environments filled with metal dust, fumes, and atmospheric moisture. The Phillips drive head allows for straightforward installation and removal using standard tools found in any welder's kit, facilitating quick field repairs or scheduled maintenance. Using non-standard or generic hardware in high-amperage gouging torches can lead to poor fitment, loosening due to thermal cycling, or even electrical tracking if the screw does not sit flush. By selecting the genuine Arcair 97-192-125 screw, operators ensure that their K4000 torch remains reliable, safe, and ready for heavy-duty metal removal tasks.

Maintenance personnel and tool crib managers recognize the importance of stocking genuine spare parts to minimize downtime. This screw is a small but essential part of the K4000's bill of materials. Regular inspection of torch hardware is recommended, as vibration and thermal expansion/contraction can loosen fasteners over time. Replacing worn or missing screws immediately with the correct part number ensures the longevity of the expensive torch handle and head assembly.
