64102996 - ESAB 0.25 Inch Bronze Split Lock Washer

Reliable Fastening with the ESAB Bronze Lock Washer

The ESAB 64102996 is a premium 0.25-inch (1/4") bronze lock washer designed to provide secure fastening in a variety of industrial and welding applications. When it comes to maintaining the integrity of your equipment, every component matters, down to the smallest washer. This specific hardware piece is engineered from high-grade bronze, a material chosen for its unique combination of strength, corrosion resistance, and electrical properties. Unlike standard steel washers, bronze offers superior longevity in environments where moisture or chemicals may be present, ensuring that your assemblies remain rust-free and functional over time.

The primary function of this split lock washer is to prevent nuts and bolts from loosening under vibration. In the dynamic environment of a workshop or job site, machinery is constantly subjected to movement and oscillation. The helical split design of this washer acts like a spring; when compressed, it exerts a continuous axial force against the fastener head and the mating surface. This tension increases friction and bites into the metal, effectively locking the fastener in place. This mechanism is critical for maintaining the safety and performance of welding machines, power tools, and structural assemblies.

Beyond its mechanical locking capabilities, the bronze material makes this washer particularly suitable for electrical connections. Bronze is a conductive alloy, making this washer an excellent choice for grounding points, terminal studs, and other electrical interfaces within welding power sources. It ensures a consistent electrical path while mechanically securing the connection. Additionally, bronze is non-magnetic, which is often a requirement in specialized electronic assemblies or near sensitive instrumentation where magnetic interference must be minimized. Whether you are performing a routine repair, assembling new equipment, or restocking your hardware inventory, the ESAB 0.25" Bronze Lock Washer delivers the reliability and performance professional tradespeople demand.
