Headless Screw Insert for Wood – Metal Thread Insert Hex Socket Drive Nu-Bolt Fastener Connector for Furniture Hardware

描述

1. Performance & Material Properties
   • Hardened Carbon-Steel Core – Stamped from C1045 steel and heat-treated for ≥600 MPa tensile strength and ≥350 MPa yield strength, providing robust pull-out resistance in wood substrates.
   • Precision Internal Hex-Socket Drive – Machined 5 mm–8 mm internal hexagon recess (ISO 2936) for positive engagement with standard Allen keys or driver bits, minimizing cam-out and allowing controlled torque application.
   • Zinc-Electroplated & Custom Finish Options – Standard trivalent zinc coating (8–12 µm) offers ≥240 h salt-spray resistance (ASTM B117). Optional nickel, black-oxide or powder-coat in any RAL/Pantone color available for décor coordination and enhanced corrosion protection.
   • Self-Tapping Wood Threads – External coarse wood-thread geometry cuts cleanly into softwood, hardwood, MDF or particleboard without pre-tapping, while internal metric (M6–M12) or UNC (¼″–½″) threads accept machine bolts, studs and furniture connectors.
2. Detailed Application Range
   • Knock-Down & Flat-Pack Furniture – Widely used in ready-to-assemble bed frames, wardrobes, cabinet carcasses and table legs sold by IKEA, Wayfair, Home Depot and Amazon.
   • Custom Cabinetry & Joinery – Secures drawer slides, face frames and decorative panels in residential and commercial millwork; stocked by McMaster-Carr, Würth and Rockler.
   • Fixture & Display Assembly – Mounts retail fixtures, POS kiosks, exhibition booths and store shelving systems—available on Alibaba, eBay and RS Components.
   • Marine, RV & Outdoor Furniture – Ideal for boat interiors, camper van conversions and patio sets exposed to humidity; offered by Grainger, Fastenal and specialty OEM suppliers.
3. Effortless Installation & User Convenience
   • Drop-In & Drive-In Method – Drill a pilot hole (Ø = major thread diameter minus 0.5 mm), insert the insert’s knurled barrel flush, then drive home with an Allen key, insertion bit or dedicated impact tip—no separate tool required.
   • Precise Torque Control – Internal hex socket allows installation with hand-held electric drivers or torque-limited wrenches, ensuring correct clamp loads without over-driving or substrate damage.
   • Reusable & Service-Friendly – Once installed, accepts repeated bolt insertions and removals (≥20 cycles) without thread wear; nuts remain captive for easy maintenance or reconfiguration.
   • Assortment Kits & Templates – Sold in mixed-size kits (50–500 pcs) with color-coded trays, drill-guide plates and installation instructions through Amazon, AliExpress, Fastenal and RS Components.
4. Premium Quality & Long-Term Reliability
   • ISO-Certified Production – Manufactured under ISO 9001 and ISO 14001 systems to DIN 16903 and ANSI B18.6.3 standards, with full batch traceability and material certificates available on request.
   • Rigorous Validation Testing – Each batch endures ≥240 h neutral salt-spray (ASTM B117), 1 000 insertion/removal cycling and pull-out testing (>2 000 N) to ensure lasting performance in wood substrates.
   • Vibration & Shock Resistance – Knurled barrel and serrated flange prevent rotation under dynamic loads up to 10 g and thermal cycling from –20 °C to +80 °C, maintaining clamp integrity in transport and use.
   • Environmental & Safety Compliance – RoHS- and REACH-compliant; free from hexavalent chromium and other restricted substances, ensuring safe use in residential, commercial and children’s furniture.
