Self-clinching studs, thin sheet are a type of stud that is designed to be installed in thin sheet metal. The stud has a small, tapered head that allows it to be crimped into a hole that is smaller than the diameter of the stud. This makes it possible to install the stud without distorting or damaging the sheet metal. Self-clinching studs, thin sheet are typically made of steel or stainless steel and are available in a variety of sizes and finishes.
