The Jack Nut Threaded Insert is an economical blind fastener designed for assembly-line use in thin, soft, or brittle materials. When tightened, the body collapses to form legs which grip the inside of the mounting surface, leaving a permanent, reusable threaded insert. Available in steel, brass, and steel with PVC or Raintite® coating.

Standard Jack Nut Threaded Inserts are manufactured of steel with commercial zinc plating. Brass is available upon special request (brass requires a 50,000 piece minimum order).

All Jack Nut threaded inserts can be supplied with coated flanges. Two types of coatings are offered. The first, called Raintite® is used for sealing ambient moisture. The second is a hard plastic coating (PVC) which is used in areas where additional protection is needed against scratching (for example, painted panels). Both can also assist with galvanic corrosion concerns.
