From the heart of Hamilton’s industrial landscape, Latham Steel has built a reputation for reliability and precision, qualities embodied in our Alloy Steel Grade 10.9 bolts. Forged from superior materials, these fasteners are the unsung heroes in projects where failure is not an option. We understand that the integrity of your work depends on the smallest components, which is why we supply bolts engineered to meet the most demanding specifications, providing the foundational strength that our clients in New Zealand and beyond have trusted for years.
The exceptional strength of Grade 10.9 bolts comes from a specific alloy composition, primarily chromium and molybdenum, which gives them their robust character. Through a controlled quenching and tempering process, they achieve a minimum tensile strength of 1000 MPa, hence the ‘10.9’ designation. This means they offer an impressive yield strength and are engineered to withstand immense loads and resist shock without deforming. Essentially, they provide a remarkable balance of high strength and good toughness, making them far superior to standard hardware options.
