Type CLA self-clinching nuts are designed for installation in aluminum sheets up to 0.125 in. thick, providing load-bearing threads with a serrated clinching ring to resist rotation. The CLA-632-2 variant is a #6-32 thread size nut with a shank code of 2, compatible with 0.056 in. minimum hole size and requiring a minimum edge distance of 0.27 in. The nut has a head diameter of 0.280 in. and a height of 0.213 in. Pushout strength ranges from 1,000 to 1,500 lbf in 5052-H34 aluminum, and torque-out resistance ranges from 110 to 21 in.·lbf.
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.
