Self-clinching standoffs are a type of fastener that is used to provide a secure connection between two objects. The standoff has a threaded end that is screwed into a hole in one object, and a crimped end that is inserted into a hole in the other object. The crimped end of the standoff expands when it is inserted into the hole, creating a secure connection. Self-clinching standoffs are typically made of steel or stainless steel and are available in a variety of sizes and finishes.
