CLA-M3-5-1 is a self-clinching nut designed for aluminum sheets, with a nominal thread size of M3 x 0.5, a shank length of 1.38 mm, and a minimum sheet thickness of 0.77 mm. It installs in sheets up to 1.4 mm thick and requires a hole size of 4.22 mm. The nut features a serrated clinching ring to prevent rotation after installation and a head diameter of 6.35 mm. Minimum edge distance is 4.8 mm. The part is compatible with aluminum sheets with hardness up to HRB 50.
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.
