M45x2 Thread – characteristics and application

What is the M45x2 thread?

The M45x2 thread is a precision metric thread with a nominal diameter of 45 mm and a pitch of 2 mm. It is a fine-pitch thread, used mainly in power hydraulic systems where high tightness, strength, and resistance to high pressure are required. This type of thread can be found, among others, in hose ends, fittings, and connection elements used in industrial machines and specialized vehicles.

Characteristic features of the M45x2 thread

The M45x2 thread is characterized by a large outer diameter with a relatively small pitch, which ensures a strong and stable connection, resistant to loosening under vibrations. The fine pitch (2 mm) allows for precise adjustment and control of the tightening torque, which is important in connections requiring tightness – e.g., in hydraulic or pneumatic connectors. Threads of this type are usually made according to the ISO 724 or DIN 13 standard.

Application of the M45x2 thread

M45x2 threads occur in:

• hydraulic and pneumatic fittings,

• high-pressure hose ends,

• valve bodies, actuators, and hydraulic control valves,

• mounting elements in heavy industry,

• oil and lubrication systems.

In power hydraulics, the M45x2 thread is most commonly used as an external connection (e.g., on hose ends), working with an internal thread of the same characteristics. This type of connection ensures tightness without the need for excessive tightening force, which translates into the safety of the system's operation.
