A claw nut, also known as a T-nut, is a type of fastener with a barrel-shaped body and a flange that has prongs or "claws" on one end. They are used to create a secure, internal thread in materials like wood, plywood, and composite materials, and are common in furniture assembly for attaching legs, shelves, and other components. The prongs dig into the material to prevent the nut from spinning, providing a strong and stable connection that can be easily assembled and disassembled.

The 4-Pronged Zinc-Plated Wood Furniture T-Nut is engineered to establish permanent, heavy-duty internal threading within timber, composites, and particleboard substrates. Available in a comprehensive range of metric and imperial dimensions from M4 to M10 (1/4" to 1/2") and lengths spanning 8mm to 25mm, these fasteners deliver exceptional anchoring capability. Manufactured from selected carbon steel (grades 4.8 to 12.9 yielding 400-1200MPa tensile strength), 40Cr alloy steel, or premium stainless steel (A2-40 to A4-80), they cater to demanding structural requirements. The exterior undergoes precise finishing—including zinc plating, hot-dip galvanizing, chrome, or nickel coating—ensuring maximum corrosion resistance. This hardware is efficiently packaged in 25kg partitioned cartons or heavy-duty fumigated pallets to support large-scale assembly lines.
When constructing heavy oak dining tables, MDF storage cabinets, or modular bookcases, achieving a perfectly flush, secure joint is critical.
Zero Spinning: Completely eliminates the frustration of the nut rotating during bolt insertion, saving valuable production time.
Flush Finish: The flat flange sits entirely level with the wood surface, allowing for unhindered stacking or delicate veneering.
Aesthetic Integration: Utilizing M6 nickel-plated variants guarantees a solid, visually unobtrusive connection when attaching metal keyboard trays to luxury executive desks.
In rigorous environments, these fasteners excel at anchoring plywood backplanes to rigid Q235 steel frames. The M10 size boasts a remarkable shear strength, making it indispensable for electrical control cabinets and heavy-duty shelving units. Furthermore, they are vital in temporary dormitory construction, securely fastening wooden floorboards to metal joists to withstand dynamic.
For custom interior upgrades, these nuts provide the hidden strength needed for floating shelves, heavy wall art, and custom garden planters. When fixing sofa legs, wardrobe hanger rods, or heavy-duty drawer runners, the deep internal threads ensure a wobble-free grip. The thick zinc-plated coating offers a visually clean, bright finish while actively resisting moisture, making them perfectly suited for humid environments like bathroom vanities or kitchen cabinetry.
Engineered for heavy stress, the M8 8.8-grade variant demonstrates a shear strength of ≥12kN and an impressive pull-out force of ≥10kN when seated in dense hardwoods like oak. It comfortably supports 100kg static loads without any thread deformation. The sharpened prongs penetrate deeply (≥5mm) into softwoods, locking the base firmly in place.
Purpose-built for wooden structures, the four aggressive gripping claws bite firmly into the substrate. This specialized design provides superior torsional resistance, ensuring the fastener will never slip or loosen, even when installed in blind holes where rear access is impossible. The flat-profile head guarantees a perfectly flush finish, enhancing both the structural integrity and the aesthetic appeal of the final product.
Select stainless steel or nickel plating for humid and outdoor environments where moisture is prevalent. Carbon steel with zinc plating delivers excellent cost-effectiveness for indoor applications, while alloy steel is reserved for heavy industry requirements. All applied surface coatings strictly adhere to environmental standards, ensuring safe integration into consumer goods.
Available in Coarse (UNC 1/4"-20), Fine (UNF 1/4"-28), and Metric (M6×1.0) configurations. The threads are machined to a precise 60-degree profile with a 6H tolerance grade and a surface roughness of Ra ≤1.6μm. A reinforced 0.5mm fillet at the thread root drastically reduces stress concentrations, preventing cross-threading and stripping during repeated assembly cycles.
Every production batch is subjected to extreme pull-out force evaluations and prolonged salt spray testing. The premium 5-8μm zinc-plated layer acts as a formidable barrier against oxidation, ensuring the hardware remains rust-free and structurally sound even after prolonged exposure to damp or outdoor conditions.
Simply pre-drill a pilot hole approximately 0.5mm smaller than the barrel diameter, insert the cylinder, and tap the flat head with a mallet until the prongs are flush with the surface. If modifications are required, they can be gently extracted using standard pliers without causing severe splintering or damage to the surrounding wood fibers.
We adapt our manufacturing to meet highly specific dimensional requirements. Whether you need oversized M12 diameters for massive hotel lobby tables, ultra-thin 5mm barrels for delicate 8mm particleboard, or specialized prong designs—such as 15-degree barbed teeth for maximum grip in soft pine, or completely flat prongs for fragile veneered plywood—we engineer the exact profile required.
Select from an extensive array of metallurgical options tailored to your operational environment:
35CrMo Alloy Steel: Tensile strength ≥900MPa, ideal for bakery equipment operating at temperatures up to 150℃.
316L Stainless Steel: Carbon content ≤0.03%, perfect for marine-grade deck furniture exposed to salt spray.
304 Stainless Steel: Ultra-smooth finish (Ra ≤0.8μm), designed for sanitary food-grade worktables.
To mitigate the risks associated with new product development, we provide comprehensive preliminary support. Procurement teams receive complimentary pre-production samples for physical evaluation. Our engineering staff also conducts thorough blueprint assessments and offers precise guidance on optimal drilling diameters and impact installation techniques, ensuring your assembly line operates flawlessly from day one.
From retail-ready 10-50 piece blister cards featuring custom logos and multi-lingual instructions, to euro-sized pallets optimized for continental distribution, we tailor the packaging to your workflow. For high-volume manufacturing, we utilize 1-ton moisture-proof bulk bags labeled with project-specific routing marks for immediate warehouse integration.
We maintain a highly transparent and flexible tiered pricing structure designed to support scale. Whether you are initiating a small-batch trial run or executing a massive OEM contract requiring extensive quantities, our cost-reduction models significantly lower your overall procurement expenses as volume increases.
To keep your assembly lines moving without interruption, we maintain a vast standing inventory of standard DIN, ISO, and ANSI specifications for immediate dispatch. For specialized OEM non-standard orders, we guarantee a strict 30 to 60-day delivery window, providing absolute predictability for your production schedules.
Safeguarding the physical integrity of the hardware during transit is paramount. We employ a multi-layered protective strategy utilizing heavy-duty anti-moisture sealed bags, reinforced partitioned corrugated cartons, and ISPM-15 compliant fumigation-free wooden pallets. This rigorous approach guarantees zero rust and zero transit loss, even during extended maritime shipping and prolonged warehouse storage.
