For an inexpensive internally threaded fastener, look no further than the Jack Nut Fastener! These fasteners are a cost-effective component used to quickly join a parent material with a secondary attachment (join two materials together). Rivet Nut USA, a division of Cardinal Components, has them in stock every day for just-in-time delivery into your production line.
Warning! Jack Nut Fasteners are tough to find, many manufacturers don’t stock Jack Nuts, instead they are treated as a special made-to-order specialty fastener with a 26+ week leadtime. But, you are in good hands as here at Rivet Nut USA (a division of Cardinal Components, Inc.), as we have Jack Nuts in-stock or just a week away, due to the good obtainability within our supply chain.

The benefits of a Jack Nut Fastener are no damage or warpage to soft plastics or thin sheet metals, fast to install, economical to purchase and easy to use!
A Jack Nut fastens quickly and securely into a parent application, without needing access to the backside of the parent application. A secondary attachment then can be affixed to the parent application, by threading a bolt through the secondary attachment into the Jack Nut. The Jack Nut sometimes can be considered a “lighter duty” version of a Bollhoff PLUSNUT®, the Jack Nut is less expensive and offers less threads, and (much) less performance than a PLUSNUT®.
The mounting parent can be materials that are thin, soft, or brittle. This includes materials such as:
- Thin sheet metal
- Soft plastics
- Wood
- Ceramic
- Delicate glass, and more!
When tightened, the Jack Nut Fastener body upsets and collapses to form four points that grip the backside/inside of the mounting parent surface, leaving a reusable threaded insert on the frontside.
Installation is a breeze with a Jack Nut! These fasteners can be installed with extreme ease due to the four large slots cut into the Jack Nut body. At low volumes, they can be installed with a nut, bolt and two wrenches, most of which are probably already in your toolbox. At medium or higher volumes, a manual or pneumatic tool could do the trick.
Jack Nuts are available in a variety of material and plating options! In-stock materials include steel (zinc plating) or brass, but we have options that add special coatings to further improve performance. Those coatings provide corrosion resistance, or we can add a special PVC, color, or rubber coating to prevent scratching soft parent material. Jack Nut Fasteners are RoHS and REACH compliant unless a non-RoHS or non-REACH material or plating is specifically requested by the customer.
Additional Jack Nut Fastener Benefits:
- Less sensitive to the hole size. For example, an oversized hole could work out fine with a Jack Nut.
- Offer a very wide grip range, to grip thin and thick materials, which helps consolidate the amount of SKUs that a company may need to stock.
- Extremely easy to remove, use a smaller driller bit and simply drill the Jack Nut out, it will likely come out in two pieces and a brand new Jack Nut can be reinstalled in the same hole.

They are typically used in applications that don’t require critical/structural engineering performance, such as holding on a dated inspection plate that gets taken on and off every year, a stationary electrical enclosure or in a utility drawer. Jack Nut Fasteners work exceptionally well in applications with extremely thin materials, upsetting in materials as thin as a piece of paper! Jack Nuts are made via battle-tested manufacturing processes that create long-lasting quality so you can be certain that a Jack Nut will perform well in the right fastening solution for your non-load bearing application.
Assembly Applications:
- Aerospace
- Automotive
- Agriculture
- Recreational Vehicles
- Electronic Components
- Manufacturing (dishwashers, refrigerators, any sort of thin metal or enclosure, etc.)
