A definitive guide for procurement officers, structural engineers, and automotive assembly specialists.
When lightweighting structural assemblies using tubular steel, thin metal sheets, or composite panels, conventional round rivet nuts present a critical vulnerability: Spin-Out under high dynamic torsional loads. The Tuerca Inserto Hexagonal (Hexagon Threaded Insert Nut) eliminates rotation failure by fitting into a laser-cut or punched hex hole, transferring rotational force to the flat geometric surfaces of the parent sheet metal.
Modern industrial applications—ranging from Electric Vehicle (EV) battery trays to high-vibration railway enclosures—demand zero-failure mechanical joints. The Tuerca Inserto Hexagonal provides a permanent, reusable internal thread (M3 to M12) in thin sheets where tapping threads is structurally impossible.

|---|---|---|---|---|---|
| M4 x 0.7 | Full Hexagonal | Carbon Steel (Zinc Plated) | 6.0 mm (+0.1/-0) | > 6.2 Nm | > 7,800 N |
| M5 x 0.8 | Full Hexagonal | Stainless Steel AISI 304 / 316 | 7.0 mm (+0.1/-0) | > 11.5 Nm | > 12,400 N |
| M6 x 1.0 | Half Hex / Full Hex | Aluminum Alloy 5052 | 9.0 mm (+0.1/-0) | > 16.0 Nm | > 14,200 N |
| M8 x 1.25 | Full Hexagonal | Carbon Steel (Cr3+ Yellow/Clear) | 11.0 mm (+0.1/-0) | > 38.0 Nm | > 26,500 N |
| M10 x 1.5 | Full Hexagonal | Stainless Steel 316 / Nickel-Zinc | 13.0 mm (+0.1/-0) | > 68.0 Nm | > 38,000 N |
Leveraging advanced cold-forming technologies, rigorous quality control, and scalable manufacturing ecosystems.
WUXI AIPLLE operates under strict automotive-grade IATF16949-2016 quality management systems. Our automated optical sorting machines guarantee defective rates below 50 PPM, protecting high-speed assembly lines from jammed installation tools.
Our facility houses modern multi-stage high-speed cold heading equipment. By cold-forming the hexagonal shank rather than machining it, internal steel grain flow remains unbroken, resulting in superior shear and tensile loading characteristics.
We offer customized plating options including Cr3+ trivalent zinc, eco-friendly zinc-nickel plating (withstanding 1000+ hours neutral salt spray test without red rust), and black oxide finish for high-corrosion outdoor environments.
Deploying specialized threaded inserts across critical structural sectors globally.
High-strength Tuerca Inserto Hexagonal fasteners are heavily used in aluminum battery pack housings, vehicle frame brackets, seat rails, and door hinge reinforcements. Fast installation ensures low cycle times in robotic cell environments.
In renewable energy projects, stainless steel (AISI 316) hex insert nuts secure solar panel aluminum framing and inverter control boxes against dynamic wind loads and environmental moisture ingress without loosening.
Sheet metal fabricators assembling server racks, telecommunication enclosures, and HVAC equipment utilize countersunk hex insert nuts to maintain flush external walls while providing heavy-duty internal threading.
