Coupling Nuts - Rolled Thread Design | High Strength, Superior Surface Finish For High Pressure Applications

Threading:
We provide the COUPLING NUTS to our customers with rolled threads. These threads are different from the regular threads and machined threads. As the application of these COUPLING NUTS are for very high pressures, Rolled threads are far more superior then the regular and machined threads in many ways like:
1. First and foremost, Rolled Threads are many times stronger then regular machined threads as the threads are formed with high pressure and the granules are compressed to form the thread. As there are unbroken flow lines with compressed grains the tensile strength and shear strength of the nut is increased due to cold working (please see the figure below). Therefore, the nut can resist the high pressure of hydraulic and pneumatic and hence resulting into Non- Failure of the product.
2. Very good surface finish of the threads as the threads are formed. Enabling the application of the nut with ease.

Basically used in FUEL INJECTION PIPES for all Vehicles and HOSE PIPES for High Pressure Hydraulic Application. As the application of these nuts is for high pressure Cold Forged Nuts are more suitable for the same.

Application Areas:
* Fuel Injection Pipes for all Vehicles.
* High pressure Hydraulic Hose Pipes for big earth moving equipments like JCBs etc.
* High Pressure Pneumatic pipes.
