For sheet metal components below 1mm thickness studs provide high torque resistance. These are also known as flush head studs or clinch studs or punch studs etc.
Installation
Self-clinching studs are installed by placing them in a punched or drilled hole in the steel or stainless steel sheet material and squeezing them into space with any regular punch or press machines. All that is required is a flat or recessed punch and a plain anvil having a hole to clear the thread diameter so that force is applied between the top of the stud head and the underside of the steel material. The squeezing action forces the ribs of the stud into the sheet displacing sheet material causing it to fill the annular groove under the lead of the stud.
The Illustrations below indicate suggested tooling for applying installation force. Nate that for sheet 060°/1.57, mm and thicker the anvil requires only a straight thru-hole to accommodate the stud. For sheets, less than .060°/1.51 mm the hole requires a countersunk with dimension at the top to provide for metal flaws around the shank of the stud.
SL Fasteners Pvt. Ltd. keeps steel studs and stainless steel studs as per the below sizes.
