From the industrial heart of Hamilton, Latham Steel has built a strong reputation for supplying robust and reliable components to New Zealand’s trade and engineering sectors. Our commitment to quality is perfectly represented in our Alloy Steel Grade 8.8 washers. We understand that the integrity of a project often relies on these seemingly small parts, which is why we ensure our washers provide the dependable strength and performance that professionals require to get the job done right, every single time.
The Grade 8.8 alloy steel used in these washers is specifically engineered for resilience. Its composition includes carbon, manganese, and often boron, which work together to create a robust material. This results in excellent mechanical properties, including a minimum tensile strength of 800 MPa and a yield strength of 640 MPa. In simpler terms, this means the washer can handle substantial loads and resist deformation under high stress, making it a trustworthy component in demanding situations.

You’ll commonly find Grade 8.8 washers hard at work in construction, heavy machinery, and critical automotive assemblies. Their primary role is to distribute the load from a bolt or nut, preventing damage to the connected surfaces and ensuring the fastener stays securely tightened. Whether it’s supporting a structural steel beam, securing a piece of industrial equipment, or being part of a high-stakes engineering project, this washer provides that essential layer of security that keeps everything firmly in place and functioning safely.
