Using gaskets or anti-skid pads can reduce the loosening of window screws
Loosening of window screws is often caused by a combination of factors, including but not limited to improper installation, material fatigue, environmental factors (such as wind pressure, temperature changes) and long-term vibration. Loosening not only affects the sealing performance of windows, resulting in large temperature differences between indoors and outdoors and increased noise, but may also endanger the structural safety of windows, and even cause safety accidents in serious cases. Therefore, taking effective measures to prevent and solve the problem of loosening window screws is of great significance to improving the overall performance of buildings and the comfort of residents. In order to effectively reduce the loosening of window screws, using gaskets or anti-skid pads is a simple and effective solution.
Gaskets, as a thin part between screws and mounting surfaces, mainly play the role of increasing contact area, dispersing pressure, preventing leakage and reducing friction and wear. In the application of window screws, it is crucial to choose the right gasket material (such as rubber, silicone, metal, etc.) and size. Rubber or silicone gaskets can effectively fill the small gap between screw holes and screws due to their good elasticity and sealing properties, enhance the fastening effect, and prevent loosening caused by vibration or thermal expansion and contraction. At the same time, these materials also have a certain shock-absorbing effect, which can further protect the window structure from external impact.
Anti-skid pads are auxiliary materials with anti-skid functions. Their original design intention is to increase the friction between the contact surfaces and prevent sliding or falling off. In the application scenarios of window screws, anti-skid pads are usually designed to be used in combination with gaskets or directly integrated into the screw heads. Through special texture design or the application of polymer materials, anti-skid pads can significantly increase the friction between the screws and the mounting surface, and maintain a stable fastening state even under harsh environmental conditions. In addition, some advanced anti-skid pads also have a self-locking function, which can automatically lock after the screws are tightened, further reducing the risk of loosening.
The material selection of gaskets and anti-skid pads is crucial. The ideal material should have good corrosion resistance, sufficient strength, appropriate flexibility and good sealing performance. Common gasket materials include rubber, silicone, PVC, nylon, etc., each of which has different advantages and disadvantages and is suitable for different environments and needs. For example, rubber gaskets are often used in places that require shockproof and leakproof due to their good elasticity and sealing properties; while silicone gaskets perform well in extreme climatic conditions due to their high temperature resistance and aging resistance.
Anti-slip mats pay more attention to the friction coefficient of the surface and are usually made of materials with high friction coefficients, such as specially treated rubber, silicone, or plastics with anti-slip textures. These materials can increase the friction between the screw and the screw hole, thereby effectively preventing the screw from loosening.
From raw material procurement to production and processing, to finished product inspection, every link of Yuyao Cili Machinery Co., Ltd. is strictly controlled. The company is equipped with a professional quality inspection team and uses advanced testing equipment and methods to ensure that the dimensional accuracy, material properties and surface quality of each screw meet or even exceed industry standards.
