The main functions of hexagonal bolts with threaded holes on the head include anti-theft, anti loosening, and anti slip.

Anti theft: The wire hole design of the hexagonal bolt head allows only special internal hexagonal wrenches or specialized rotating heads to be disassembled. This special structure can effectively prevent unauthorized disassembly and has anti-theft function.

Anti loosening: Due to the strong tightening of the hexagonal bolt head, it is more secure under the action of torque, effectively preventing the screw from loosening. In addition, by introducing fixed pins and other materials, the bolt's tensile strength and load-bearing capacity can be increased, making it less prone to sliding and having a better anti loosening effect.

Anti slip: The hexagonal design of the hexagonal bolt head can more firmly hold the wrench, prevent sliding, and increase tightening force and safety.

Application scenarios

Hexagonal perforated bolts are widely used in various fields such as machine manufacturing, automotive parts, electronic equipment, aerospace, furniture, and construction. Especially in electronic devices and furniture, hexagonal perforated bolts have almost become "standard", demonstrating their practicality and safety.

Maintenance and upkeep

During use, it is important to choose appropriate materials and tools, as special tool requirements may increase the difficulty and cost of maintenance and upkeep. In addition, the use of flat pads and spring pads can also enhance the anti loosening effect of bolts. Flat pads are mainly used to adjust height, increase contact surface, stabilize friction coefficient, and prevent bolt strain, while spring pads are mainly used for anti loosening.
