Car repair gecko expansion description

Product Introduction：
The car repair gecko is a mechanical fastener made of stainless steel, featuring strong corrosion resistance and easy installation. Its main purpose is to be applied to the anchoring connection of concrete structures, natural stone and metal components, and it is suitable for heavy-load facilities and industrial building scenarios. According to manufacturing standards, they can be classified into national standard products. The performance grades cover 4.8 and 8.8 grades, and the thread specifications adopt standardized design. When installing, it is necessary to ensure that the expansion clamp ring is fully extended to obtain a reliable fastening force. The calibrated tensile force value is based on the cement strength of 260 to 300kgs/cm² as the test benchmark.
Product features：
The car repair gecko is made of 304 stainless steel, which has better corrosion resistance than ordinary carbon steel and can adapt to industrial atmospheres, coastal environments and humid indoor Spaces. Its thread length design is convenient for installation and operation, and it has low requirements for the depth and cleanliness of concrete holes, and is often used in heavy-load facilities. Two performance grades, 4.8 grade and 8.8 grade, can be selected according to the load requirements.
Application field:
It is mainly applied in the following scenarios:
1. Building structure: Curtain wall fixation, support plate installation, railing connection
2. Industrial equipment: Mechanical base anchoring, beam reinforcement
3. Infrastructure: Connection of bridge components, installation of power facilities
4. Special environments: Corrosive environments such as chemical equipment and coastal buildings
Installation Precautions：
The following technical specifications must be followed during the installation process:
The diameter of the borehole should be strictly matched with the product specifications
The expansion clamp ring must be fully extended and must not fall off or deform
The actual safe load shall not exceed 25% of the rated value
On-site load-bearing capacity tests should be conducted in areas where the cement strength does not meet the standards
