The Heavy Duty Galvanized Expansion Screw, a robust and innovative metal product by Hebei Tengyun New Materials Co., Ltd, is meticulously designed for secure industrial use. This indispensable fastener comprises a precision-engineered screw paired with either a durable steel pipe or an iron cylinder. One end of the screw features a meticulously threaded design, while the other end tapers elegantly to amplify its functionality. Strategically positioned cuts adorn one end of the steel pipe or iron cylinder, enhancing its adaptability and grip. The brilliance of this expansion screw lies in its wedge-shaped slope, which, upon installation, conjures an immense frictional force. This force arises from the strategic expansion of the steel pipes, ensuring an unwavering hold and a steadfast, fixed effect. This makes it the ideal choice for a plethora of decoration occasions. Its applications are expansive, including but not limited to, securing air conditioners, water heaters, range hoods, and anchoring frameless balcony windows. It's also perfect for installing anti-theft doors and windows, affixing essential kitchen and bathroom components, and providing reliable support for ceiling screws, ensuring everything stays in place with unmatched stability and security.
