High-Performance M4-M10 Claw Nuts: The Secure Fastening Solution for Wood
In the furniture manufacturing and woodworking industries, stability and durability are paramount. Our M4-M10 Claw Nuts, also widely known as Four-Prong T-Nuts, provide a robust internal thread in wood, particle board, or composite materials. These specialized fasteners are designed to be driven into the material, where their four sharp prongs bite deep into the surface, ensuring the nut remains locked in place even under high vibration or torque.
Whether you are assembling heavy-duty cabinetry, office furniture, or climbing walls, our zinc-plated claw nuts offer a flush-fit finish that combines aesthetic appeal with industrial-grade strength. Available in a full range of metric sizes from M4 to M12, we cater to both large-scale manufacturers and specialized wholesalers.
- Superior Anti-Rotation: The four-prong design acts as an anchor, preventing the nut from spinning during bolt installation or removal.
- High-Grade Material: Manufactured from premium carbon steel with Yellow or White Zinc Plating for excellent corrosion resistance in indoor and outdoor environments.
- Precision Threading: Every M6 and M8 claw nut undergoes rigorous thread-go/no-go gauge testing to ensure seamless bolt compatibility.
- Flush Mounting: The flat base allows the fastener to sit flush against the wood surface, preventing interference with other components.
Selecting the right size is critical for structural integrity. Below are the standard dimensions for our most popular metric claw nuts.
| Thread Size | Base Diameter (mm) | Barrel Height (mm) | Hole Size (Suggested) |
|---|---|---|---|
| M4 | 15 mm | 6 mm | 5.5 – 6.0 mm |
| M5 | 17 mm | 8 mm | 6.5 – 7.0 mm |
| M6 | 19 mm | 9 mm/12mm | 7.5 – 8.0 mm |
| M8 | 22 mm | 11 mm/15mm | 9.5 – 10.0 mm |
| M10 | 25 mm | 13 mm | 11.5 – 12.0 mm |
Our Four-Prong Claw Nuts are versatile fasteners used across various sectors:
- Furniture Production: Ideal for sofas, beds, chairs, and flat-pack (KD) furniture assembly.
- Climbing Walls: Specifically M10 T-nuts are the industry standard for securing climbing holds to plywood panels.
- Cabinetry & Shopfitting: Provides strong anchor points in MDF and particle board for shelving and display units.
- Speaker Construction: Used to mount heavy drivers into wooden enclosures without stripping the wood.
Proper installation ensures the maximum load-bearing capacity of the fastener:
- Drill the Hole: Use a drill bit slightly larger than the barrel diameter of the claw nut (refer to our table above).
- Insert the Nut: Place the claw nut into the hole from the opposite side of where the bolt will enter.
- Seat the Prongs: Use a hammer to gently tap the nut until the prongs are fully embedded in the wood. For mass production, a pneumatic press is recommended.
- Tighten the Bolt: As the bolt is tightened, it will pull the nut further into the wood, increasing the grip.
Q: What is the best material for Claw Nuts?
A: Zinc-plated carbon steel is standard for dry indoor furniture. For humid or outdoor environments, 304 Stainless Steel Claw Nuts are recommended to prevent rust.
Q: Do you offer custom barrel lengths for M8 T-nuts?
A: Yes, we provide OEM services. We can customize the barrel length and base diameter based on your material thickness and load requirements.
