Our Industrial Heavy Duty Expansion Screw, a sophisticated fusion of engineering excellence and robust design, consists of a high-grade metal screw paired with a durable steel pipe or iron cylinder. This ingenious product is meticulously crafted, featuring a threaded end and a precisely tapered opposite end. In addition, the steel pipe or iron cylinder is innovatively designed with strategically positioned cuts at one end, ensuring optimal performance. The operational magic of our expansion screws lies in their wedge-shaped slope, which ingeniously generates substantial frictional grip force. This is accomplished through the expansion of the steel pipes, resulting in unmatched stability and fixed positioning. Our expansion screws are versatile and indispensable, finding widespread application in various decorative and structural settings. They are perfect for securely fastening essential household and industrial fixtures such as air conditioners, water heaters, and range hoods. Additionally, they provide reliable fixing for frameless balcony windows, anti-theft doors and windows, kitchen and bathroom fixtures, and are ideal for securing ceiling structures. Trust in the unparalleled durability and security provided by Hebei Tengyun New Materials Co., Ltd's Industrial Heavy Duty Expansion Screws for all your installation needs.
