Carbon Steel Car Repair Gecko
Product Features
This product has a longer thread for easier installation and is often used in heavy duty installations.
To obtain a reliable, huge tightening force, it is necessary to ensure that the clamping ring fixed to the gecko is fully expanded. And the expansion clamp ring must not fall off the rod or be twisted and deformed in the hole.
The calibrated tensile force values are all tested under the condition of cement strength of 260~300kgs/cm2, and the maximum safe load shall not exceed 25% of the calibrated value.
Application field
Suitable for concrete and dense natural stone, metal structures, metal profiles, base plates, support plates, brackets, railings, windows, curtain walls, machines, girders, stringers, brackets, etc.
