Type CLA self-clinching nuts are designed for installation in aluminum sheets with a hardness of HRB 50 or less. The CLA-M3-2 variant has a metric M3 thread and is suitable for use in 0.025 in. (0.64 mm) thick aluminum. Installation pushout resistance for M3 CLA nuts in 5052-H34 aluminum ranges from 800 to 1500 lbf, with torque-out resistance between 6 and 27 in.-lbf depending on thickness. A serrated clinching ring prevents rotation after installation.
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.
