The 12-point bolt features a unique head with 12 sides, which makes it with superior torque resistance and rotational accuracy than traditional hex bolts. With its 12-point structure, this bolt offers high torque resistance, making it ideal for environments that require high tightening force.
The 12-point bolt requires a 12-point wrench for installation, which provides a better grip and control. The bolt surface treatment provides excellent protection against corrosion, enhancing durability in tough environments.
The 12-point bolts are widely used in aircraft manufacturing and maintenance, including for securing parts like the fuselage, hydraulic systems, and engines. Essential for securing automotive manufacturing, including engines, chassis, and bodywork, ensuring the vehicle's safety and reliability. They are also used in heavy-duty machinery and industrial applications.
