- Heavy hex structural bolts are designed to withstand the load of a steel-to-steel connection.
- Commonly used in structural steel joint in construction and building applications.
- Class 10.9 steel is an alloy steel, quenched and tempered, with a minimum tensile strength of 1,040/mm-2 (Mpa).
- The washer face under the head provides a precision bearing surface.
- The chamfered point improves engagement with a nut or pre-tapped hole.
