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 Four Claws Furniture T-Nut is for wood/composite internal threading (furniture, construction, DIY). Sizes: M4-M10 (1/4"-1/2"), lengths 8-25mm; grades include carbon steel 4.8-12.9 (tensile strength 400-1200MPa) and stainless steel A2-40/A2-70/A2-80/A4-80. Materials: carbon steel (45#/Q235), alloy steel (40Cr), 304/316 stainless steel; finishes: zinc plating (5-8μm), HDG, chrome, nickel. Complies with DIN 562, ISO 8673, ANSI B18.2.2, and is certified by ISO9001-2008, SGS, CTI, RoHS. Packaged in 25kg partitioned cartons or fumigated pallets (≥500kg).
Assembles bookcases, oak tables, and MDF cabinets. 45° prongs create ≥50N·m anti-spin force (M8 size) to prevent nut spinning; flat top ensures flush finish. E.g., M6 nickel-plated T-nuts attach metal keyboard trays to luxury office desks.
Secures 18mm plywood backplanes to Q235 steel frames (shear strength ≥8kN for M10) in electrical cabinets, and wooden floorboards to metal joists (2.5kN/m² load) in temporary dormitories. Speeds modular construction by 30%.
Fixes sofa legs, wardrobe rods, and drawer runners. Used for wooden wall art, floating shelves, and garden planters. Zinc plating resists rust in bathrooms/kitchens.
M8 8.8-grade T-nuts have shear strength ≥12kN, torque ≥80N·m, pull-out force ≥10kN (oak wood), supporting 100kg without deformation. Prongs penetrate ≥5mm in softwoods for stable use.
Stainless steel/nickel plating for humid/outdoor use; carbon steel zinc plating for indoor cost-effectiveness; alloy steel for heavy industry. All coatings meet RoHS standards.
Offers UNC (1/4"-20), UNF (1/4"-28), and metric (M6×1.0) threads (60° profile, grade 6H, Ra ≤1.6μm). Reinforced thread root (0.5mm fillet) prevents stripping.
Pre-drill a hole (0.5mm smaller than T-nut), insert, and hammer prongs flush. Removable with pliers without wood damage.
Customizes diameter (e.g., M12 for hotel tables), length (5mm ultra-thin for 8mm particleboard), and prongs (barbed 15° teeth for softwoods, flat prongs for veneered plywood).
Uses 35CrMo alloy steel (tensile ≥900MPa) for ≤150℃ bakery environments, 316L stainless steel (carbon ≤0.03%) for marine furniture, and 304 stainless steel (Ra ≤0.8μm) for food-grade worktables. Provides custom samples.
Offers 10-50pcs blister cards (with specs/instructions/logos) for retail, custom-sized pallets for Europe, and 1-ton moisture-proof bags for wholesale. Labels include multilingual info or project-specific marks.
