Jack Nuts

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. Jack nuts are ideal for installing a strong captive steel thread into materials which would be unsuitable for other techniques, or where the hole is too large for the thread you wish to use.

Features and benefits:

• 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
• Suitable for a wide grip range

Jack Nuts are suitable for the following materials:

• Any rigid thick material and blind holes where a rivet nut is either out of grip or cannot get a purchase.
• Wood, chipboard, particle board, hardboard, MDF and most other wood products.
• Glass reinforced plastics (GRP) .
• Most rigid plastics (PVC, polythene, polypropylene etc, etc)
