Product Characteristics

This product has longer thread, is easier to install, and has better effect than the traditional expansion screw. It is usually used in heavy-duty facilities.
To obtain reliable and huge fastening force, it is necessary to ensure that the clamp ring fixed on the gecko is fully expanded. And the expansion clamp ring shall not fall off from the rod or twist and deform in the hole.。
The rated tension value is obtained by testing under the condition of cement strength of 260~300kgs/cm2, and the maximum value of safety load shall not exceed 25% of the rated value.

Working Principle

When the nut is tightened, the screw moves outward, and the conical part moves through the axial movement of the thread, thus forming a large positive pressure on the peripheral surface of the expansion pipe. In addition, the angle of the cone is very small, so that a friction self-locking is formed between the wall, the expansion pipe and the cone, so as to achieve the fixing effect
