This product has longer threads and is easier to install. It is often used in heavy-duty installations. To obtain a reliable and huge tightening force, it is necessary to ensure that the clamp ring fixed on the gecko is fully expanded. And the expansion clamp must not fall off the rod or twist or deform in the hole. The calibrated tensile force values are all tested under the conditions of cement strength of 260 ~ 300kgs / cm2, and the maximum value of the safety load must not exceed 25% of the calibrated value.Suitable for concrete and dense natural stone, metal structures, metal profiles, floor plates, support plates, brackets, railings, windows, curtain walls, machines, beams, beams, brackets, etc.1. Material: Wedge anchor bolts are usually made of high-strength steel or stainless steel, which has high strength and corrosion resistance. 2.
