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, it 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.
