Structural features

Hexagonal head: provides a larger torque application area, which is convenient for operation with a wrench or socket, and can achieve a tighter connection. Compared with other shapes of bolt heads, it is less likely to slip when tightening.
 

Tail hole: The hole is processed at the tail of the bolt, mainly used to install a cotter pin, wire or other locking device to prevent the bolt from loosening due to vibration, impact and other reasons during use, and improve the reliability and safety of the connection.

Specification parameters

Thread specifications: Common thread specifications range from M6 to M48, and different thread specifications are suitable for different connection strengths and application scenarios.

Length range: Generally, there are different lengths such as 90mm-260mm, and the specific length depends on the actual use requirements.
Tolerance grade: According to relevant standards, such as GB/T 32.1, etc., there are strict regulations on the dimensional tolerance of bolts to ensure their interchangeability and reliability in different applications.

Application fields

Mechanical manufacturing: used for the assembly and fixation of various mechanical equipment to ensure that the various parts of the equipment remain tightly connected during operation and prevent the parts from loosening due to vibration.

Construction engineering: in building structures, it is used to connect steel structure components, concrete components, etc. to ensure the stability and safety of the building structure.

Automotive industry: used for the connection of parts in automobile engines, chassis, body and other parts, which can withstand the vibration and impact force during the driving of the car and ensure the reliability and safety of the car.

Power equipment: in power equipment such as power generation equipment and transmission line towers, it is used to fix and connect various electrical components and structural components to ensure the stability and safety of power equipment during operation.

Function advantages

Anti-loosening: by inserting a locking device such as a cotter pin or a metal wire into the tail hole, it can effectively prevent the bolts from loosening under vibration or impact loads, improve the reliability of the connection, and reduce equipment failures or safety accidents caused by loose bolts.

Easy to install and disassemble: in some occasions where frequent disassembly and installation are required, the tail hole can be used as an insertion point for auxiliary tools, which is convenient for operators to use tools to tighten and loosen the bolts and improve work efficiency.

High customizability: According to different application requirements, the length, diameter, thread specification, material, and tail hole size and shape of the bolt can be customized to meet various special connection requirements.
