Installation Procedure

1. Ensure mating threads are clean and free of debris. 2. Hand-thread the screw to verify alignment and prevent cross-threading. 3. Tighten the screw to the specified torque value using an appropriately sized wrench or socket, avoiding over-tightening to prevent thread stripping or material deformation.
