1400-0166 - Victor 3/8-16 x 2.25 Hex Head Tap Bolt - Steel

Genuine Victor Replacement Hardware

The Victor 1400-0166 is a specialized Hex Head Tap Bolt designed to meet the rigorous standards of industrial welding and cutting equipment. Manufactured from high-quality steel, this fastener is engineered to provide reliable structural integrity for Victor apparatus assemblies. As a genuine OEM part, it guarantees dimensional accuracy, ensuring that maintenance personnel can perform repairs without the concerns of thread mismatch or material incompatibility often associated with generic hardware.

Technical Specifications

This bolt features a 3/8-16 UNC (Unified National Coarse) thread pitch, a standard specification that balances tensile strength with ease of assembly. The "16" denotes sixteen threads per inch, providing a robust grip suitable for heavy-duty machinery. The bolt measures 2.25 inches in length, a specific dimension chosen to accommodate the flange thicknesses and mating parts found in Victor equipment. Crucially, this is a "Tap Bolt," meaning it is fully threaded from the tip to the underside of the hex head. This full-thread design distinguishes it from standard hex cap screws, which often feature a smooth shank, allowing this bolt to be screwed all the way into a tapped hole without bottoming out on a shank, or to be used with a nut in applications requiring extensive adjustment.

Material and Durability

Constructed from industrial-grade steel, the 1400-0166 bolt is built to withstand the mechanical stresses and thermal cycles common in welding environments. While not specified as stainless, standard steel bolts in these applications typically feature a finish to resist minor corrosion during storage and use. The hex head design is compatible with standard imperial wrenches and sockets, facilitating easy installation and removal during routine maintenance or emergency repairs. Proper torque application is essential to maintain the safety and performance of the equipment this bolt secures.

Application in Maintenance

In the context of MRO (Maintenance, Repair, and Operations), using the correct fastener is critical. Substituting a partially threaded bolt where a full-thread tap bolt is required can lead to loose assemblies or damage to the internal threads of the equipment. The Victor 1400-0166 ensures that the clamping force is applied correctly and that the equipment remains safe to operate. Whether replacing a lost fastener or swapping out a worn component during an overhaul, this bolt restores the equipment to its factory specifications.
