For aluminum connectors, a typical torque range is between 8 and 12 Nm (Newton-meters) for M6 bolts and between 15 and 20 Nm for M8 bolts. . Torque is a measure of the force that causes an object to rotate. In the context of photovoltaic bracket connectors, it's the amount of force you need to apply when tightening the bolts or screws to secure the connectors in place. If you don't apply enough torque, the connectors might come loose. . When securing photovoltaic (PV) bolts during the installation of solar panels, applying the correct torque is critical to ensure a secure mount without causing damage to the bolts or the mounting structure. Us a 13mm hex socket and torque to 13Nm (10 ft-lbs). Proceed with the m Mounting Systems, Mounting Devices, Clamping/. Set Screw Torque Speci ication SCHD.
