The CLA-256-1 is a self-clinching nut designed for installation in aluminum sheets, featuring a .086-56 thread size and a shank code of 1. It has a maximum sheet thickness of 0.040 in, a hole size of 0.086 in, and a minimum edge distance of 0.19 in. The nut is made for aluminum panels with hardness of HRB 50 or less, and includes a serrated clinching ring to prevent rotation 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.
