Always de-energize and lock out equipment before removing or installing set screws on rotating components such as pulleys, collars, or fan hubs. Verify thread size and engagement depth before torquing to avoid stripping threads in the receiving component. Follow applicable equipment manufacturer guidelines for fastener torque and seating requirements.
