Type CLA self-clinching nuts are designed for installation in aluminum sheets up to HRB 50 hardness, providing load-bearing threads with high pushout resistance. They feature a serrated clinching ring to prevent rotation after installation and are compatible with Class 3A/4h or Class 2A/6g screws. The nut installs into properly sized holes through cold flow of the sheet metal around an undercut.
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.
