Direct-from-factory cold-formed threaded inserts, open-end, closed-end, hex, and structural blind rivets engineered for global OEM applications.
In modern industrial manufacturing and high-velocity assembly lines, securing strong, load-bearing threads into thin-gauge sheet metals, composite panels, or hollow tubular profiles presents a major structural challenge. Tapping threads directly into materials under 3mm thickness frequently results in stripped threads, structural deformation, and catastrophic joint failure under fatigue loading. The engineering solution chosen across global automotive, solar, electrical, and aerospace sectors is the Tuerca Remachable (internationally recognized as the Rivet Nut, Threaded Insert, or Remache Tuerca).
A Tuerca Remachable is a tubular internal-threaded fastener designed to be installed completely from one side of the workpiece ("blind installation"). Using a specialized pneumatic, hydraulic, or battery-actuated setting tool, the unthreaded shank portion of the insert is upset (collapsed radially) to form a robust, high-strength retaining bulge on the reverse side of the panel. Concurrently, the threaded internal chamber remains dimensionally intact, creating a permanent, highly durable female thread capable of accepting standard metric (M3–M12) or imperial machine screws under high torque conditions.
Information Gain Insight: Unlike traditional weld nuts that require high energy consumption, specialized labor, and risk thermal distortion or surface damage to pre-painted/zinc-plated materials, cold-formed tuercas remachables are installed post-finish without damaging surface coatings or introducing heat-affected zones (HAZ).
The mechanical performance of a rivet nut joint is governed by three primary structural metrics: Torque-to-Yield (Spin-Out Resistance), Pull-Out Force (Tensile Strength), and Shear Load Capability. At WUXI AIPLLE METAL PRODUCTS CO., LTD., our engineering team selects precise metallurgical formulations tailored to specific load profiles:
| Thread Size | Body Type Options | Sheet Thickness Range (Grip) | Hole Size (+0.10mm) | Pull-Out Strength (N) - Steel | Torque-Out Resistance (N·m) - Hex |
|---|---|---|---|---|---|
| M3 x 0.5 | Round Knurled / Full Hex | 0.5 mm – 2.0 mm | 5.0 mm | 3,200 N | 4.5 N·m |
| M4 x 0.7 | Round Knurled / Full Hex / Flat Head | 0.5 mm – 2.5 mm | 6.0 mm | 5,800 N | 9.2 N·m |
| M5 x 0.8 | Knurled / Hex / Reduced Head | 0.5 mm – 3.0 mm | 7.0 mm | 9,500 N | 16.5 N·m |
| M6 x 1.0 | Full Hex / Half Hex / Knurled Body | 0.7 mm – 3.5 mm | 9.0 mm | 14,200 N | 32.0 N·m |
| M8 x 1.25 | Full Hex / Heavy Duty Knurled | 1.0 mm – 4.0 mm | 11.0 mm | 22,800 N | 65.0 N·m |
| M10 x 1.5 | Full Hex / Large Flange Structural | 1.0 mm – 5.0 mm | 13.0 mm | 34,500 N | 115.0 N·m |
To eliminate spin-out failure and optimize aesthetic integration, global procurement engineers must select the precise geometry corresponding to their mechanical sheet design:
Designed specifically for hexagonal punched holes. The hex geometry completely prevents rotation inside the sheet metal even when dynamic high-torque power tools are used for screw driving. Ideal for automotive chassis and heavy machinery.
Features outer longitudinal knurling that bites into the surrounding material wall upon expansion. Provides exceptional spin-out resistance in round drilled or laser-cut holes across softer metals like aluminum or fiberglass.
Flat Head: Offers maximum load-bearing flange surface to distribute high clamp loads.
Reduced/Micro Flange: Provides a virtually flush surface fit without requiring countersink machining on thin sheet metals.
Features a fully enclosed bottom cap designed to seal against liquids, vapor, and gas ingress. Essential for outdoor electrical control cabinets, automotive underbodies, and marine fuel tanks requiring IP67 waterproof certification.
China's Yangtze River Delta industrial belt—specifically Wuxi, Jiangsu—represents the global apex of precision cold-forming technology and raw material supply chain integration. WUXI AIPLLE METAL PRODUCTS CO., LTD. leverages these regional manufacturing cluster synergies to deliver unmatched quality-to-cost ratios for enterprise buyers worldwide.
Our operational superiority is backed by strict compliance with international quality standards. Holding both ISO 9001 and the rigorous automotive-grade IATF 16949-2016 quality management certifications, WUXI AIPLLE enforces zero-defect manufacturing protocols across every stage of cold forging, threading, electroplating, and optical inspection.
Our state-of-the-art facility integrates multi-station high-speed cold heading machinery capable of forming complex hollow geometries with sub-micron consistency:
Utilized extensively in body-in-white (BIW) structures, battery housing trays, door hinges, interior dashboard subframes, and bumper brackets. Full hex steel and nickel-zinc automotive nuts prevent loosening under intense engine vibration and chassis flex.
High-strength stainless steel 304/316 and coated aluminum tri-fold blind fasteners enable rapid mounting of solar module frames, cable trays, and inverter boxes onto galvanized steel strut channels in remote solar farms.
Provides watertight, dustproof IP67 threaded joints for aluminum outdoor enclosures, server racks, air conditioning compressors, and sheet metal ductwork where single-sided assembly is mandatory.
Lightweight structural rivets and non-standard custom threaded inserts secure internal trim panels, luggage racks, lighting fixtures, and seating frames in passenger trains and commercial aircraft.
