Type CLA self-clinching nuts are designed for installation in aluminum sheets up to HRB 50 hardness, providing load-bearing threads with high pushout and torque-out resistance. The CLA-M2-2 variant features an M2 thread size and is compatible with 0.64 mm thick aluminum sheets. Installed using a parallel squeezing force, the nut cold-flows into an undercut and is secured by a serrated clinching ring to prevent rotation. Performance data for CLA nuts in 5052-H34 aluminum shows a pushout force range of 3.56-6.67 kN and torque-out resistance of 0.4-1.02 N•m for M2 threads.
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.
