The High-Strength Expansion Screw from Hebei Tengyun New Materials Co., Ltd is an ingeniously crafted metal component, designed to deliver unrivaled anchoring power for both industrial and heavy-duty applications. Comprising an intricately threaded screw and a robust steel pipe or iron cylinder, this product epitomizes engineering excellence. At one end, the screw features precise threading, while the opposite end is skillfully tapered; the steel pipe or iron cylinder is meticulously designed with strategic cuts. The core principle behind this expansion screw's superior performance is its wedge-shaped slope, which is masterfully engineered to produce an immense frictional grip force. This force is generated as the steel pipes expand, ensuring an unwavering and secure fixation. This versatile marvel finds its application in an array of decoration scenarios, including secure installation of air conditioners, water heaters, and range hoods. It also proves indispensable in fixing frameless balcony windows, anti-theft doors and windows, and various kitchen and bathroom components.
