Direct from China’s leading cold-heading precision fastener manufacturing facility. High-torque, anti-rotation blind threaded inserts engineered for demanding assembly environments.
In modern structural engineering, thin-walled sheet metals, extruded aluminum profiles, and tubular hollow sections present a fundamental joining challenge: tapped threads lack sufficient thickness to withstand high torque loads.
A Tuerca Remachable Hexagonal (known globally as a Hexagonal Blind Rivet Nut or Tuerca Ciega Hexagonal) is an internally threaded tubular fastener designed for installation from a single side of a panel. Unlike traditional smooth-body round rivet nuts, hexagonal threaded inserts feature a six-sided outer shank that seats perfectly into a matching hexagonal laser-cut or punched hole.
This geometric lock completely eliminates the primary failure mode of blind fasteners: spin-out under high installation or service torque. When mated with high-tensile bolts, the hexagonal geometry distributes torsional stress across six flat bearing surfaces rather than relying solely on friction or knurling.
When specifying wholesale Tuerca Remachable Hexagonal components, engineering teams must evaluate structural load parameters to select the optimal shank configuration:
WUXI AIPLLE METAL PRODUCTS CO., LTD. utilizes certified raw wire materials to manufacture high-yield strength hexagonal rivet nuts tailored to aggressive operational environments.
Cold-formed from high-grade SAE 1008/1010 or 10B21 boron steel. Formulated for superior ductility during blind expansion while preserving internal thread hardness. Available with trivalent blue/zinc plating, yellow zinc chromate, or ultra-durable Nickel-Zinc (Ni-Zn) plating for salt spray resistance exceeding 1,000 hours without red rust (ISO 9227).
Essential for marine, medical, food processing, and chemical industries. Grade 304 (A2-70) provides outstanding atmospheric corrosion protection, while Grade 316 (A4-80) includes molybdenum additions for immunity to chloride pitting. Passivated finish ensures zero surface contamination.
Engineered for automotive lightweighting and aerospace sub-assemblies. Offers an exceptional strength-to-weight ratio, non-magnetic properties, and high thermal conductivity. Perfect for joining delicate aluminum sheet structures without galvanic corrosion risk.
