Attributes:
● Material: Usually made of carbon steel or stainless steel, such as A2, A4 stainless steel. The common property classes of carbon steel are 4.6 and 8.8.
● Specification: The thread specifications range from M6 to M24, and the length generally ranges from 20mm to 200mm.
● Thread Type: Metric machine thread.
● Head/Body: T - shaped square neck structure.
Features:
●Easy to Install: The T - shaped square neck design allows the bolt to be directly inserted into the T - shaped slot without additional tools to fix the bolt head, which is convenient and quick.
● Good Anti - loosening Performance: The square neck is closely matched with the T - shaped slot. When the nut is tightened, the bolt will not rotate, effectively preventing loosening and ensuring the reliability of the connection.
● Strong Applicability: It can be used for T - shaped slot structures of different materials and shapes, and is suitable for a variety of industrial scenarios.
Applications:
● Construction Field: In the construction of high - speed railways and rail transit, it is used to fix track fasteners, brackets, etc. In curtain wall decoration, it can fix curtain wall keels and other components.
● Industrial Equipment: It is often used for the installation and fixation of various mechanical equipment, such as machine tools, lifting equipment, etc., connecting the various components of the equipment together.
