Type CLA self-clinching nuts are designed for installation in aluminum sheets with a hardness of HRB 50 or less. The CLA-440-2 variant features a .112-40 thread, a shank code of 2, and is compatible with sheet thicknesses up to 0.056 in. It has a head thickness of 0.187 in, a shank diameter of 0.166 in, and requires a hole size of 0.187 in. The minimum distance from the centerline to the edge is 0.22 in, and the clinching ring provides rotation resistance 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.
