High Tensile Bolts

High tensile bolts are manufactured from steel with a reduced carbon content, alloyed with elements like chromium or molybdenum to enhance strength and durability.

Metric high tensile bolts are typically classified into three strength grades: 8.8, 10.9, and 12.9, with some variants exceeding these grades. These numbers indicate the bolt's minimum tensile strength and yield strength, which are marked on the bolt and corresponding nuts for easy identification.

Other thread standards use their own grading systems to classify high tensile strength, ensuring compatibility across various applications.
