When using, it is necessary to use an impact drill (hammer) to drill holes of the corresponding size on the fixed body, and then load the bolt and expansion pipe into the hole, and tighten the nut to make the bolt, expansion pipe, installation and fixed body become one.

After tightening, it will expand, the tail of the bolt has a large head, the bolt is set with a round pipe slightly larger than the diameter of the bolt, the tail part has several openings, when the bolt is tightened, the tail of the big head is brought to the open tube, the pipe is enlarged, to achieve the purpose of expansion, and then fix the bolt on the ground or wall, to achieve the purpose of rooting.


1. Wide applicability. As long as the male thread size is suitable, it is suitable for any form of anchor head type.

2. Construction method selection. It can be preset at a fixed point according to demand, or drilled (installed) in a single construction line, and its function and effect are completely consistent.

3. High construction success rate. There is no depth of drilling and drilling tilt trouble, and the construction completion rate is 100%.

4. High-pitched pull design. Full tooth taper expansion special inverted hook design.

5. Lock anti-loosening effect. The special design of the full-tooth taper expansion uses the reverse thrust effect to urgently lock into the workpiece.

6. Improve design thinking. Short and concise, suitable for all commercially available screws, DIY and fortification most satisfactory construction options.

7. Ensure the expansion of the anchor. Metal plate pressing products, patented full-tooth taper expansion design, strong gripping ability, no idling, no need for professional construction skills.

8. No trouble in disposal. As long as the anchor workpiece is withdrawn, the filler is applied to restore the plane, and there is no risk of excision and protrusion impact.
