About High Tensile Hex Screw
Our organization is one of the pioneers deeply engaged in offering High Tensile Hex Screw. This screw is used to fasten wood to wood, or metal to wood. High Tensile Hex Screw is rigorously checked on various quality parameters before delivering at customer end. Moreover, this screw is perfect for projects such as docks, bridges, highway structures, and buildings.
High-tensile hex screws (or bolts) are heavy-duty, six-sided head fasteners engineered from heat-treated alloy or carbon steel for superior strength and durability. Typically used in structural, machinery, and automotive applications, they offer high load-bearing capacity and stress resistance, commonly available in Grades 8.8, 10.9, and 12.9.
