Custom Engineering

After 20 years of working on industrial bolts, we have solved almost all imaginable bolt challenges. Let our engineering team show you our results.
In order to improve production efficiency, TorcStark provides free engineering consultation and proposes the most effective solution for your bolting problem. After measuring application process or sharing CAD files, our engineering team will customize a solution that suits your work and when the design is completed, we will perform finite element analysis and other computer-aided stress tests to ensure the durability and longevity of the solution, and will create a 3D printing model to test the installation and operation. Once the design is perfect, the final product will be thoroughly tested in our laboratory to ensure safety and efficiency.
Please contact us by email, phone, and online chat. TorcStark will provide the perfect solution for your project!

Hydraulic Torque Wrench Tutorial

The square drive hydraulic wrench tightens the bolts under the power of the hydraulic torque pump. It reasonably finds the support point of the reaction arm, applies pressure to the hydraulic torque wrench many times, and then allows the bolts to reach the maximum torque.

Hydraulic Bolt Tensioner Tutorial

First fix the bolt tensioner to the bolt, then start the hydraulic torque pump to apply pressure to the hydraulic bolt tensioner to lift the nut, then use a wrench to tighten the nut, and finally release the pressure of the hydraulic torque pump and remove the bolt tensioner. The bolts are tightened.

Hydraulic Torque Pump Toturial

Press the switch of the hydraulic torque pump several times and rotate the hydraulic valve to adjust and preset the pressure of the hydraulic torque pump.
