Type CLA self-clinching nuts are designed for installation in aluminum sheets with a hardness of HRB 50 or less. The CLA-M4-2 variant provides metric M4 threads with a pushout load range of 5.78-8.01 kN and a torque-out resistance of 3.27 N·m when installed in 5052-H34 aluminum. A serrated clinching ring prevents rotation after installation. The nut's shank diameter and head configuration are compatible with standard installation tools for self-clinching applications.
Self-clinching nuts are installed by placing them in properly sized holes in sheets and applying a parallel squeezing force to the head of the nut. The sheet metal surrounding the head cold flows into an undercut thereby making the fastener an integral part of the sheet. A serrated clinching ring prevents the fastener from rotating after installation.
Type CLA aluminum nuts are recommended for use in aluminum sheet with a hardness of HRB 50 or less on the Rockwell “B” scale.
Unplated threads are sized to accept a basic go gauge after .00025” plating.
