Installation Procedure

1. Ensure the mating threads are clean and free from debris. 2. Hand-tighten the screw to engage the threads properly. 3. Use an appropriate wrench or socket to tighten the hex head to the required torque, avoiding over-tightening which can damage the nylon. 4. Verify secure fastening and proper alignment of components.
