1.   After a hole to prescribed size has been drilled or punched into the parent material the stainless steel Captive Nut or Stud is inserted so that the hexagonal head rests on the surface of the material. Pressure is applied to the hexagonal head forcing it into the material.

2.   The material that is displaced, as the hexagonal head is forced in, flows into a recess around the insert. The nut is now a permanent part of the parent material. The flow of material into the recess prevents the insert from being pushed or pulled out. The embedded hex head offers tremendous resistance to torque.

No special tools are needed to perform this simple installation, applying pressure, ion. Any device capable of applying pressure, such as an arbor press, may be used.
