Products Description

Double head bolts have threads on both ends, one end is often screwed into the threaded hole of the connected part as the basis of fastening, and the other end is used to install nuts to connect other parts. Its material covers carbon steel, stainless steel, alloy steel, etc., can be flexibly selected according to the use of environment and strength requirements. Carbon steel material is cost-effective and suitable for general mechanical connections. Stainless steel material has strong corrosion resistance and is commonly used in special environments such as chemical and food processing. Alloy steel material has excellent strength and can cope with high strength, high temperature, high pressure and other harsh working conditions. It is widely used in petrochemical pipeline connection, heavy machinery assembly and automobile engine fixing. With its unique structure, it can effectively enhance the solidity and reliability of the connection to ensure the safe operation of equipment and engineering structures.

Advantages of double head bolts

Strong firmness

both sides of it can be connected on the mechanical structure, so its firmness is higher than the single head bolt. The groove thread design improves the shear strength of the structure and has a better connection effect.

Convenient installation

Since the thread lengths of both sides of the double-headed bolt are equal, it can be installed in a back-and-forth reversal.

High structural stability

it is threaded on both ends and does not require additional nuts, simplifying the installation process and enhancing the stability of the connection. This design reduces the effect of nut loosening and improves the reliability of the connection.

High load-bearing capacity

Its threaded design on both ends allows it to evenly distribute the force, providing higher load-bearing capacity for application scenarios that require high tensile or torsional forces.‌
