Concrete Heavy Duty Screw Anchor Title:

4.8 & 8.8&12.9 Grade concrete anchor screw self tapping screw concrete anchor bolt for heavy duty


Core structural characteristics - Head design:

Hex Flange Head: Increases the pressure bearing surface to prevent sinking into the substrate and provide high torque transmission capability.

The material is mainly carbon steel (SAE J429 Gr.5/8.8 grade), with surface galvanized or Dacromet (DAC) anti-corrosion treatment.


Thread technology:

Wide tooth spacing+deep thread: enhances concrete bite strength and reduces screw in torque.

Self Drilling: Some models come with a cutting edge at the end, allowing for simultaneous drilling and tapping (different from regular self tapping screws).

Working principle - dual function integration:


Self Tapping: The tail thread can be self cut or extruded to form a mating female thread without the need for pre drilled threaded holes.


Concrete Anchor: By using special threads to mechanically interlock with concrete, it forms a tensile and tensile anchoring force.


Installation mechanism: Cooperate with electric tools to complete drilling, tapping, and fixing in one go.
