Performance & Material Properties
• Premium 304/316 Stainless Steel Construction – Machined from marine-grade austenitic stainless for tensile strength ≈515 MPa, yield ≈215 MPa and elongation >40 %, with a dense chromium-oxide film that resists rust, staining and chemical attack even in coastal or high-humidity environments.
• Four-Claw Pronged Design – Four spring-tempered claws fold flush for installation, then flare outward as the mating screw engages, creating a 360° radial anchorage in wood or composite substrates. Pull-out resistance exceeds 1.2 kN in 18 mm oak or maple panels.
• Precision-Rolled Internal Threads – Available in M4–M10 and ¼-20 to ½-13 UNC, cold-rolled threads ensure smooth engagement, high fatigue life and repeated screw cycles without wear or fretting.
• Low-Profile Flanged Head – Countersunk flange sits flush with the material face for a clean appearance; optional black oxide or custom PVD finishes provide visual contrast or color coding.
Detailed Application Range
• Furniture & Cabinetry – Ideal for knock-down assemblies, drawer runners, shelf brackets and decorative panels where concealed, permanent anchorage is required.
• Carpentry & Joinery – Secures handrails, stair nosings, wardrobe frames and built-in cabinetry in residential or commercial interiors without visible fasteners.
• Stage, Set & Exhibition Installations – Provides reliable blind-side fixation in timber trusses, plywood walls and modular display booths—supporting dynamic loads and repeated assembly cycles.
• General Woodworking & Hobbies – Perfect for DIY projects, model building, sports equipment mounts and instrument fixtures in MDF, plywood, hardwood and composite boards.
Effortless Operation & User Convenience
• True Blind-Side Installation – Drill the correct pilot hole, tap the insert flush into place, and drive the screw. Claws expand behind the panel—no backing plate or specialized fixtures needed.
• Quick, Reusable Assembly – Hammer-in seat and screwdriver or nutsetter engagement take under 5 seconds per insert. Once installed, screws can be removed and reinstalled dozens of times without compromising clamp load.
• Universal Compatibility – Works with standard wood-working bits and drivers. For high-volume jobs, compatible with pneumatic or battery-powered insertion tools for cycle times <2 s each.
• Organized Assortment Kits – Available in labeled cases containing M4–M8 and ¼-20 to ½-13 sizes (50–200 pcs), plus matching drill bits and installation guides for on-site efficiency.
Superior Quality & Long-Term Reliability
• International Standards & Certification – Produced in ISO 9001-certified facilities to meet ASTM F828 and DIN Insertion Nut tolerances (±0.05 mm), ensuring consistent dimensions and performance.
• Rigorous Testing & Traceability – Each lot undergoes pull-out, shear and torque-to-turn validation, plus ≥720 h neutral salt-spray exposure (ASTM B117). Full heat-lot traceability from raw bar to finished part with material certificates.
• Vibration & Fatigue Resistance – Four-claw geometry maintains clamp force under cyclic loads, shock and temperature changes, preventing loosening or “back-off.”
• Environmental & Safety Compliance – RoHS and REACH compliant; free from hexavalent chromium and other hazardous substances. High-purity stainless steel delivers decades of maintenance-free, corrosion-resistant service.
