The Principle of Expansion Screw Bolt
- Expansion is created by tightening a threaded bolt which draws a tapered cone expanding a sleeve against the walls of the hole.
- The purpose of a secure and reliable fixing of items and fixtures to concrete, brick, walls any solid surface really of heavy items and fitments.Screw expansion anchor bolts are mainly used in masonry applications to utilize expansion characteristics during loading. HCHHARDWARE is a leading manufacturer and supplier of the same type, such as stainless steel threaded expansion anchor bolts of different material grades. When there is lateral pressure or vibration, it is best to use expansion bolts. When there is shear load, the wedge anchor works better. Maintaining strength is provided through expansion in the application. High performance expansion anchor rods are made of high tensile materials. They come in different sizes and types. The size can change up to 500 millimeters. There are differences between use cases. Not all of these can be applied to all material surfaces.
