Grade 10.9 high tensile hex bolt millimeter are manufactured using medium carbon steel, medium carbon steel alloy and low carbon boron steel that has been quenched and tempered. Used in automotive applications and for bolting large and forged parts, metric 10.9 bolts exhibit high tensile strength and good wear resistance.

Grade 10.9 High Tensile Hex Bolt (Millimeter)

SKU: 245

It is made from high-strength steel, with the 10.9 grade referring to its tensile strength rating according to the ISO property classes system. The grade 10.9 is one of the strongest, making the bolt suitable for various applications, such as construction, automotive, and industrial machinery. Various sizes are available in millimeters when you order from us.

High Tensile bolts are made from carbon and/or alloy steel. These bolts are quenched and tempered to reach the required tensile strength. They are considered structural-grade bolts and are used in high-strength and load-bearing installations, such as automotive, construction, and machine industries. Under the metric grade of the ISO (International Standard Organization), the bolts are classed from 4.6 to 12.9, where the hardness, ductility, wear, heat resistance, and tensile strength of the bolt rise with the numerical value. The class of the bolt is punched into the head of the bolt and is a visible indication of a metric bolt. The six sides of the hex head allow a firm grip during tightening or loosening. This bolt is used with a torque wrench/gun to reach the proper preload of the bolt. Commonly with a zinc (galvanized) or plain (oiled) finish, these bolts can come with a shank and thread or with a full-threaded grip length. The bolt's diameter, length, and class depend on the manufacturer’s specifications.
