Recommended Torque Values for Bolted Connectors Tightening Force Applied to Hardware: Following are Anderson’s recommended torque values applying to all clamping hardware used in connectors and fittings. Care should be taken to prevent sealant from being applied to hardware since torque values will be affected if the hardware becomes lubricated with sealant.
