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 four legs which grip the inside of the mounting surface, leaving a permanent, reusable threaded insert. Available in steel and brass, JACK NUT threaded inserts can be coated with RAINTITE® to seal moisture and hard plastic PVC to prevent scratching and galvanic corrosion. JACK NUT threaded inserts are RoHS-, ELoV-, and WEEE-compliant.
