Grade 8.8, 10.9, and 12.9 high tensile fasteners for structural steel, machinery, and high-stress applications.
High tensile fasteners in Grades 8.8, 10.9, and 12.9 for structural steel connections, machinery assembly, and any application where standard-grade fasteners can't handle the load. The grade number indicates minimum tensile strength — higher grades hold more load in the same bolt size.
