This product has long threads, is easier to install, and is commonly used in heavy load facilities.
In order to obtain a reliable, large fastening force, it is necessary to ensure that the clamp ring fixed to the gecko is fully expanded. And the expansion clamp ring can not be removed from the rod or distorted in the hole.
The calibration tensile force values are all tested under the condition of cement strength 260~300kgs/cm2, and the maximum safety load shall not exceed 25% of the calibration value.
one-stop procurement, the price is more favorable.
