Product description
DIN933 hex bolts are fully threaded hexagon head bolts manufactured to German standard DIN 933, equivalent to ISO 4017. These bolts are made from carbon steel and heat-treated to achieve property class 8.8, offering a minimum tensile strength of 800 MPa and yield strength of 640 MPa. The threads are rolled for improved fatigue resistance, and the bolts are available in various sizes with metric coarse threads. Typical applications include structural steel connections, machinery assembly, automotive components, and general engineering where high-strength fasteners are required. As a bulk supplier and OEM manufacturer, we provide consistent quality with full traceability and can customize packaging, marking, and surface treatments such as zinc plating or hot-dip galvanizing upon request.
