For decades, Latham Steel in Hamilton has been a trusted name in New Zealand’s industrial supply chain. We take pride in our local roots and our commitment to delivering robust, high-integrity components like the Alloy Steel Grade 2H Washer. Engineered for the toughest conditions, this washer is a key part of our promise to provide Hamilton’s workshops and national infrastructure projects with fast, reliable access to materials that are built to last, ensuring safety and performance where it matters most.
The Grade 2H washer is defined by its specific alloy composition, primarily chromium and molybdenum, which gives it a distinct advantage in challenging environments. This chemistry is the foundation for its excellent mechanical properties, including a high hardness rating that resists embedding and a precise minimum yield strength. These characteristics ensure the washer maintains critical clamp load under intense pressure and vibration, preventing joint failure where standard washers might falter.
