Car repair geckos are fixed devices used to create stable connections on walls or other surfaces, also known as expansion bolts or expansion bolts. It is usually composed of bolts, nuts, washers, and outer sleeves, among which the outer sleeve is a hollow metal tube, usually made of stainless steel or other corrosion-resistant materials. The working principle of the car repair gecko is to use the expansion of the outer sleeve to fix objects. During installation, the bolt is inserted into the pre drilled hole, and then the nut is tightened. The groove or cut of the outer sleeve is squeezed during the tightening process of the nut, thereby tightly fitting with the inner wall of the hole and forming a firm connection. This connection method is suitable for very sturdy surfaces such as concrete and brick walls, and can provide adjustable tightness.
The characteristics of the car repair gecko include:
Easy to install: No special tools required, only a drill bit and a hammer or impact drill are needed for installation.
High load-bearing capacity: suitable for medium to heavy projects, such as installing large equipment or hanging ceiling grids.
Universality: Provides multiple sizes and styles to meet different application needs.
Strong support: When installed correctly, the expansion of the car repair gecko in the pre drilled concrete hole provides an incredible and powerful support.
The application fields of car repair geckos are very wide, including but not limited to concrete and dense natural stone, metal structures, bottom plates, support plates, brackets, railings, windows, curtain walls, machines, beams, beams, brackets, etc. Its thread is longer, easier to install, and is usually used in heavy-duty facilities. To obtain reliable fastening force, it is necessary to ensure that the clamp ring fixed on the gecko is fully expanded, and the expansion clamp ring cannot fall off the rod or twist or deform in the hole. The maximum safe load shall not exceed 25% of the calibrated tensile value obtained from testing under the condition of cement strength of 260~300kgs/cm2.
The design of the car repair gecko includes an extended wedge inserted into a pre drilled hole in the concrete. By tightening the screw to generate pulling force, a wedge/conical compression clip is used for expansion to generate frictional force for fixation. This design allows car repair geckos to adapt to different installation needs while providing stable connections and strong support.
The standards for repairing geckos mainly include their material, testing strength, maximum load, and application areas.
Material: Car repair geckos are usually made of stainless steel, carbon steel, and other metal materials, and the selection of these materials ensures that they have good strength and corrosion resistance.
Test strength: The calibration tensile value of the car repair gecko is tested under the condition of cement strength of 260~300kgs/cm ². This test strength standard ensures its reliability and safety in various applications.
Maximum load: The value of the safe load shall not exceed 25% of the calibration value. This regulation limits the maximum load-bearing capacity of the car repair gecko under specific conditions to prevent safety hazards caused by overload.
Application areas: Car repair geckos are suitable for the installation and fixation of various structures and facilities such as concrete and dense natural stone, metal structures, bottom plates, support plates, brackets, railings, windows, curtain walls, machines, beams, beams, brackets, etc. Its wide range of application areas reflects its versatility and practicality.
In summary, the standards for car repair geckos not only include specific requirements for their material and testing strength, but also include limitations on their maximum load and a wide range of application areas. These standards together ensure the safety and effectiveness of car repair geckos in various applications.

A double-stacked self-locking washer is a special mechanical connector designed to prevent bolts from loosening, especially in high-vibration or high-load environments.It consists of two spring washers nested inside each other in an S-shaped configuration. The outer spring washer has ends that bend inwards, while the inner spring washer has ends that bend outwards, creating a two-way self-locking feature.The working principle of this washer is based on elastic deformation. When placed between connecting parts, the inner curved part of the outer spring ring interlocks with the outer curved part of the inner spring ring, creating a locking force that prevents the connecting parts from loosening under vibration or load.The advantages of the double-stacked self-locking washer include high reliability, easy installation, and a wide range of applications.It is suitable for various mechanical connections, such as threaded connections and pin connections, and is widely used in industrial production and machinery manufacturing, especially in the automotive manufacturing process, where it is often used to connect engine and chassis systems to improve the safety and reliability of the car.
