性能与材料特性
• Robust Carbon & Alloy Steel Construction – Made from quenched-and-tempered C1045 carbon steel or 4140 alloy steel, delivering tensile strengths of 800–950 MPa and Rockwell hardness of 35–45 HRC for exceptional shear and pull-out resistance.
• Unique Four-Claw Expansion Design – Four spring-tempered claws fold inward for flush insertion, then flare outward under bolt torque to bite deeply into wood or composite substrates. This radial anchorage provides pull-out resistances up to 1.5 kN in 18 mm plywood, far exceeding standard insert nuts.
• Corrosion-Resistant & Customizable Finish – Standard trivalent zinc plating (8–12 µm) resists ≥240 h salt spray (ASTM B117); optional epoxy-polyester powder-coat in any RAL color adds UV stability, scratch resistance and visual identification.
• Precision-Machined Threads – Internal coarse or fine machine threads (M6–M12, ¼-20 to ½-13 UNC) are cold-rolled for superior root strength, smooth engagement and hundreds of screw insertion/removal cycles without thread wear.
详细应用范围
• Indoor & Outdoor Climbing Walls – Securely anchors rock-climbing holds into plywood, OSB or engineered panels, ensuring climber safety under dynamic loads and repeated impacts.
• Cabinetry & Furniture Assembly – Ideal for knock-down furniture, modular cabinets and worktops; provides flush, hidden nuts for shelf pins, decorative panels and drawer slides—no visible hardware required.
• Decorative Woodwork & Millwork – Fastens wall-mounted coat racks, handrails, signage and trim pieces in residential and commercial interiors where clean aesthetics and high load capacities are essential.
• General Wood & Composite Substrates – Works in solid wood, MDF, particleboard, hardboard and composite decking boards; perfect for point-of-purchase displays, trade-show exhibits and fixture assemblies.
操作简便，使用便捷
• True Blind-Side Installation – Drill a single pilot hole, insert the knurled nut flush with the surface, then tighten the mating bolt; the claws expand outward and lock without back-side access or special tooling.
• Fast, Repeatable Setting – Compatible with manual drivers, cordless nutsert tools or pneumatic nutsetters; typical cycle time <3 s per insert makes high-volume installations efficient.
• Hand-Start & Tool-Assisted Flexibility – Knurled outer sleeve allows quick finger-start positioning; switch to a hex socket or Phillips driver to reach full clamp torque (up to 4 Nm) in high-density boards.
• Complete Assortment Kits – Available in kits of 50–200 pieces covering M6–M10 and ¼-20 to ⅜-16 sizes, each with matching installation bits and a labeled, compartmentalized case for on-site convenience.
卓越品质与长期可靠性
• International Standards & Certification – Produced in ISO 9001–certified plants to DIN 7904 and ASTM F 468 tolerances (±0.05 mm), ensuring interchangeability and dimensional accuracy.
• Rigorous Testing & Traceability – Each batch undergoes pull-out, shear and torque-to-turn tests, plus ≥240 h salt-spray exposure; full heat-lot traceability from raw material to finished insert.
• Vibration & Fatigue Resistance – The four-claw geometry and high-clamp-load threads resist loosening under cyclic loading, thermal cycling and mechanical shock.
• Maintenance-Free Service Life – High-purity steel, robust plating and precision machining deliver decades of rust-free, high-strength performance—even in demanding indoor, outdoor or high-humidity environments.
