Type CLA self-clinching nuts are designed for installation in aluminum sheets up to 0.344 in. thick, with a minimum edge distance of 0.31 in. and a recommended hole size of 0.234 in. The CLA-032-2 variant features a .190-32 thread size and a shank code of 2, providing high pushout resistance and a serrated clinching ring for torque-out resistance. Installation requires a parallel squeezing force that causes the surrounding sheet metal to cold-flow into an undercut, making the nut an integral part of the panel. The nut is compatible with aluminum sheets having a hardness of HRB 50 or less. It is dimensionally equivalent to NASM45938/1 specifications.
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.
