WECO gives maximum torques for the wire tightening screws but does not give torques for mounting screws. The reason is that mounting screw torque will be very affected by the type of screw used and the substrate in which it is screwed. For example a wood screw into wood, plastic or sheet metal; predrilled or not, a machine screw & nut, will all have different torques. The important thing is not to deform, penetrate or break the connector dielectric moulding material because this could cause short circuits and other failures. As such the correct screw insertion criteria are correct final height of the screw head against the moulding and proper penetration into the mounting surface so as to be solid without damaging anything. The drawings on the website will help in determining this. This also requires that screw heads (and washers if used) be correctly sized. Too large can cause penetration into sidewalls and too small can cause excessive stress on the mounting hole. WECO sometimes recommends a mounting screw type, but never torque.
