BONOSS Forged Grade 12.9 Extended Wheel Bolts are made by the forged process. The forging process offers lots of advantages over other manufacturing processes for wheel bolts. Due to the continuous intense pressure extrusion, the forging process brings superior mechanical and physical properties. Among the key advantages are:
High tensile strength and tough, safe and secure
Hard and durable, guarantee long-term applications
Better wear resistance and higher fatigue strength
Elimination of porosity, evenly and tight internal structure
Good polishing and finishing surface characteristics
It is worth mentioning that the grade of the bolt is 12.9, and the bolt performance grade for steel structure connection is divided into more than 10 grades such as 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9, among which the bolts of 8.8 and above. The material is low-carbon alloy steel or medium-carbon steel and is heat-treated (quenched, tempered), which are generally called high-strength bolts, and the rest are generally called ordinary bolts. The bolt performance grade label consists of two parts of numbers, which respectively indicate the nominal tensile strength value and the yield ratio of the bolt material. The selection of the highest grade screw material reflects the dedication to product quality.
