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.

Features:

• Fastens in blind holes.
• Won't distort or deform soft plastics or thin sheet metals.
• Fast, inexpensive and easy to use.
• Not hole-size sensitive.
• Fastens securely despite burrs or uneven substrate.
• Available with 'Plastisol' coating for sealing purposes.
• Suitable for a wide grip range.
• Can be set with manual or pneumatic tools.
• Removable.
