Post Tightening Strategy

Post Tightening Strategy

The Post Tightening strategy is a two-step process designed for precise and secure fastening by ensuring accurate screw seating and applying a final specified torque.

Steps:

1. Locate Screw:

   • The tool starts by rotating slowly in reverse while moving downwards.
   • This phase carefully positions the bit onto the screw head.
   • The tool either detects it's fully seated or a slight torque increase (indicating the bit catching the edge), signaling a successful "locate screw" step.

2. Tightening:

   • Similar to the Quick Tightening strategy, this step begins with a lower RPM in the tightening direction.
   • The tool monitors for a torque rise, indicating the screw is nearing its final position.
   • Once detected, the tool switches to torque control and applies torque until the pre-programmed torque target is achieved.

Benefits:

• Accuracy and Control: The locate screw step ensures proper bit seating, preventing damage and improving tightening accuracy.
• Secure Fastening: By applying the specified torque, this strategy guarantees a strong and secure assembly.

Applications:

• Post Tightening is ideal for situations requiring critical joints with precise torque control.
• It's commonly used following a Quick Tightening pre-tightening step to achieve the final, high-precision fastening.
