Series CKN self-clinching KAL hex nuts are engineered to provide strong, load-bearing internal threads in sheet materials as thin as 1.0 mm. The hexagonal body design enhances torque resistance by preventing rotation during installation and service, improving fastening reliability in high-load applications. Manufactured from heat-treated carbon steel with zinc clear finish, CKN nuts deliver high pushout and torque-out performance in cold-rolled steel and aluminum panels. Designed for materials with Rockwell hardness up to HRB-80, these fasteners are suitable for industrial equipment, sheet metal fabrication, enclosures, and structural panel assemblies requiring durable threaded connections.
