Specification and performance of expansion bolts

As a special type of fastener, expansion bolts are widely used in the connection and fixing of concrete structures. It is characterized by the bolt body and expansion sleeve composition, through the pre-drilled holes in the installation and fastening bolts, the expansion of the expansion sleeve can produce a strong connection, so as to achieve a strong and reliable effect. In terms of specifications, the specifications of expansion bolts vary from application to application, including diameter, length and expansion sleeve size. Common diameters are M6, M8, M10, etc., and the length is usually customized according to actual needs. In addition, the material of the expansion bolt is also an important factor affecting its performance, and the current common materials include carbon steel and stainless steel. Carbon steel expansion bolts are suitable for general building structures, and stainless steel expansion bolts are suitable for more corrosive environments. The bearing capacity of the expansion bolt mainly depends on its material strength and design, usually manufacturers will provide relevant technical parameters, such as maximum bearing capacity, tensile strength and shear strength, for users to choose for reference. Installation, the expansion bolt is relatively simple, usually need to drill a hole first, the bolt and the expansion sleeve assembled together, through the tool to tighten the bolt, so that the expansion of the expansion sleeve can produce fastening force. In terms of application, expansion bolts are widely used in concrete structures in construction, Bridges, mechanical equipment and other fields to provide reliable connection and fixing. In short, when selecting and using expansion bolts, different manufacturers and different models of specifications and performance may be different, it is recommended that users refer to the technical parameters and instructions provided by the manufacturer, and design and install according to the specific situation.
