Installation Procedure

1. Ensure the receiving threaded hole is clean and free of debris. 2. Thread the polycarbonate hex head cap screw by hand for the initial engagement to prevent cross-threading. 3. Tighten the screw using an appropriate wrench or socket on the hex head, applying gradual torque until the desired clamping force is achieved, avoiding over-tightening.
