Jack Nuts (Slotted Body Blind Rivet Nuts): High-Retention Threaded Inserts for Thin & Brittle Substrates

Securing robust, load-bearing threads in ultra-thin sheet metals or delicate engineering plastics has always posed a major engineering challenge. Traditional tapping often strips, while weld nuts risk thermal distortion and surface coating damage.

Engineered for demanding assembly environments, our Jack Nuts (Slotted Body Blind Rivet Nuts) offer an exceptional fastening solution. Designed for blind-side installation, they deliver reliable, high-strength female threads in soft, hollow, or brittle materials without compromising host material integrity.

Key Product Advantages

• Four-Leg Expanding Anchor for Superior Pull-Out Resistance

  During installation, the slotted body collapses into four wide-bearing legs behind the mating material. This generous footprint evenly distributes clamping loads across a broad surface area, effectively preventing pull-through even in thin-gauge materials.

• Efficient Blind-Sided Fastening

  Fully installed from one side of the workpiece, eliminating the need for rear-side access. It simplifies production line workflows, slashes assembly cycle times, and lowers overall labor overhead.

• Forgiving Hole Tolerance

  The unique collapsing mechanism easily accommodates slight variations in pre-drilled or punched hole sizes, burrs, and minor misalignments, minimizing rework rates.

• Zero Thermal Distortion & Coating Protection

  As a cold-forming mechanical fastener, Jack Nuts eliminate weld spatter and heat distortion. They can be installed seamlessly into pre-painted, coated, or plated components without marring finishes.
