Product Description

Product Description

Bolt: Mechanical part, cylindrical threaded fastener with nut. A fastener consisting of a head and a screw (a cylinder with external threads) in two parts, to be fitted with a nut, for fastening two parts with a through hole. This type of connection is called bolted connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.

 According to the force mode of the connection, it is divided into ordinary and hinged holes. According to the shape of the head: hexagonal head, round head, square head, countersunk head and so on. The hexagonal head is the most commonly used. Generally, the countersunk head is used where the connection is required.

As a key component for connecting and fixing photovoltaic modules, the bolt is widely used. Such bolts are needed in various application scenarios such as photovoltaic power plants, distributed photovoltaic systems, and solar street lights. The photovoltaic module clamping bolt can firmly fix the photovoltaic module to the bracket while maintaining a good electrical connection, thereby improving the stability and efficiency of the entire photovoltaic system. In the installation and maintenance process, it is also necessary to pay attention to the use of appropriate tools and technologies to ensure the installation quality and safety of bolts.
