Self Clinching Studs are threaded inserts made of steel with a specially formed head. They are used in thin walled moulded components made of steel, light alloy, NF metal. Clinching Studs are pressed into the moulded components with pre-punched receiving holes. During this process, the material flows out of the area of the hole wall into the annular grooves of the Studs thereby making a permanent connection. Self Stud is designed to provide wear free screw connection capable of withstanding high loads in thin walled moulded components from 1.0 mm thickness & above. These products have distinct advantages like: easy & quick installation; high torque & pull out strength; can be used in surface treated, ready plated parts, minimal outside dimensions for space and weight saving designs with an aesthetic look. These products are used in various applications such as sheet metal control panels, PCB's, UPS, Invertors, Household appliances, Medical & Pharmaceutical equipments, etc.
Clinching Studs And Pins - Type KFH/KFHS/KFHA
Flush-head for sheet thickness of .040" / 1 mm and greater
KFH (Flush Head) Studs are installed by placing them in punched or drilled holes in the sheets and squeezing into place with any standard press. The squeezing action embeds the head of the the stud into the sheet. The metal displaced by the head flows smoothly and evenly around the ribs and in to the annular groove - creating a flush head assembly and securely lockign the stud in to the sheet with high torque out and push out resistances. Other types such as Unthreaded, KTFH (Non Flush) Studs & KHFH (High Strength) Studs are also available on special order.
