99402125 - Tweco 2-5 Replacement Slotted Screw 8-32 x 5/16 Inch (10-Pack)

Genuine Tweco Maintenance Components

The Tweco 9940-2125, widely known by its industry standard part number 2-5, is a specialized slotted screw designed for the maintenance and repair of Tweco MIG welding guns. This package contains ten (10) high-quality steel screws, each featuring an 8-32 UNC thread pitch and a length of 5/16 of an inch. As a genuine OEM component, this screw is engineered to meet the exact tolerance requirements of Tweco equipment, ensuring a secure fit that generic hardware store fasteners often fail to provide. In the context of industrial MRO (Maintenance, Repair, and Operations), utilizing authentic parts is critical for maintaining the structural integrity and electrical continuity of welding apparatus.

These screws are primarily utilized in the assembly of MIG gun handles and cable connections. The 8-32 thread size is a standard specification within the Tweco Classic series and other related torch models. The 5/16-inch length is calculated to provide maximum thread engagement without interfering with internal components or protruding from the casing, which could pose a safety hazard or ergonomic issue for the operator. The slotted head design allows for simple installation and removal using standard flat-blade screwdrivers, facilitating quick field repairs or shop maintenance sessions without the need for specialized tooling.

For procurement specialists and facility managers, stocking the 9940-2125 10-pack is a proactive measure against downtime. Small fasteners are the most commonly lost or stripped items during routine torch cleaning and liner replacement. By maintaining a supply of these specific 2-5 screws, maintenance teams can ensure that welding stations remain operational. The steel construction of these screws offers necessary resistance to the thermal cycling and mechanical vibration inherent in welding operations, preventing loosening over time which can lead to increased electrical resistance and heat buildup at connection points.

Ensuring the longevity of your welding equipment starts with the smallest details. The Tweco 2-5 screw represents the manufacturer's commitment to quality, providing a reliable fastening solution that supports the heavy-duty performance expected from Tweco MIG guns. This product is essential for any comprehensive inventory of welding spare parts.
