ANSI/ASME B18.2.1 Hexagon Head Bolt

ANSI/ASME B18.2.1 automotive hexagonal bolts comply with the American National Standards Institute (ANSI) and the American Society of Mechanical Engineers (ASME) B18.2.1 standard. The bolts are designed with a standard hexagonal head, have excellent mechanical properties and reliable locking capabilities, and are used in the automotive manufacturing field, including the fastening of engines, chassis systems and structural parts to ensure the safety and stability of vehicle assembly.

The bolts are made of high-strength alloy steel and undergo a rigorous heat treatment process to improve tensile strength and fatigue life to meet the automotive industry's requirements for high-load and high-vibration conditions. In addition, its threads comply with the unified thread standard (UNC/UNF), and can provide surface treatments such as galvanizing, electroplating or Dacromet according to different usage environments to enhance corrosion resistance and extend service life.
