OVERVIEW

Precision Engineered Brass Fastener for Industrial Applications

The ESAB 63100100 is a specialized brass nut designed to meet the rigorous demands of industrial welding environments. Identified by the specifications 0.250-20, this component features a 1/4-inch major diameter with a coarse thread count of 20 threads per inch (TPI), adhering to the Unified National Coarse (UNC) standard. This specific threading ensures a robust clamping force while maintaining ease of assembly and disassembly during maintenance cycles. As a genuine OEM component, it guarantees strict dimensional adherence, preventing the issues often associated with generic hardware, such as thread stripping or poor fitment which can compromise equipment integrity.

Material selection is critical in the design of welding equipment components. This nut is manufactured from high-grade brass, an alloy primarily composed of copper and zinc. Brass offers several distinct mechanical and chemical advantages over carbon steel. Foremost is its exceptional resistance to corrosion. In welding workshops, where equipment is frequently exposed to humidity, fumes, and temperature fluctuations, steel fasteners are prone to oxidation and rust. This brass nut remains stable, ensuring that the fastener can be removed easily even after years of service, reducing maintenance downtime.

Furthermore, the material properties of brass make it uniquely suited for specific subsystems within welding machines. Brass is non-magnetic, which prevents interference in electromagnetic fields generated by transformers and inverters. It is also electrically conductive and thermally stable, making it an ideal choice for securing electrical terminals or grounding points where low resistance is required. Additionally, brass is non-sparking, a critical safety feature when working in environments containing flammable gases or vapors. Whether used in gas regulation assemblies, electrical connections, or structural mounting, the ESAB 63100100 delivers reliable performance and longevity.

Integrating genuine ESAB parts into your maintenance, repair, and operations (MRO) strategy ensures that your equipment continues to operate within factory specifications. While a nut may seem like a minor component, the failure of a fastener due to corrosion or thread fatigue can lead to significant equipment failure. By choosing the ESAB 63100100, you are investing in the continued reliability and safety of your welding infrastructure.

FAQ

The nut features a 1/4"-20 thread size, which means it has a 1/4-inch diameter and 20 threads per inch (Coarse Thread).

Brass is used for its corrosion resistance, electrical conductivity, and non-sparking properties, making it ideal for welding equipment environments.

While a steel nut might fit physically, it is not recommended. Steel can rust and seize, and it lacks the conductivity of brass which may be required if the nut is used for electrical connections.

Yes, this is a genuine ESAB replacement part, ensuring correct dimensional tolerances and material quality.

You will typically need a standard wrench or socket set that fits a 1/4" nut (usually a 7/16" wrench size, though this can vary by specific nut standard).

No, this product is sold as the nut only. If your assembly requires a washer, it must be purchased separately or reused.

It fits specific ESAB models and assemblies that call for part number 63100100 or a 1/4-20 brass nut. Check your machine's parts diagram to confirm.

No, brass is a non-magnetic material, which is beneficial in welding environments to avoid interference with magnetic fields.
