Material and Workmanship
The bolts are made from high-strength ASTM 4140 / SCM 440 steel, which is used for the production of high-stress components. To achieve the desired mechanical properties, the material undergoes a heat-treatment process. This procedure ensures consistent hardness and strength throughout the entire bolt. The properties are then verified using a tensile strength test and a salt spray test, which checks the durability of the black chrome surface finish. The bolt head is designed for a 17mm key.
