description

1. Performance & Material Properties
   • Robust Carbon & Alloy Steel Construction – Manufactured from C1045 carbon steel or 4140 alloy steel for superior tensile strength (800–1,000 MPa) and hardness (HRC 30–40), ensuring high pull-out and shear resistance once set.
   • Galvanized Zinc-Plate & Custom Color Finishes – Standard trivalent zinc plating (8–12 μm) delivers ≥240 h salt-spray resistance (ASTM B117); optional epoxy-polyester powder-coat in RAL colors for UV stability, scratch resistance, and visual coding.
   • Multi-Petal Blind Expansion Design – Five or six “spider” petals flange out behind the panel when the mandrel is drawn, creating a large bearing surface and true blind-side anchorage in materials from 1 mm to 12 mm thick.
   • Optimized Self-Locking Threads – Integrated coarse or fine threads (e.g. M5, M6, ¼-20) are machined into the insert body for precise screw engagement, minimizing fretting and maintaining clamp load under vibration.
2. Detailed Application Range
   • Composite & Wood Panels – Ideal for plastic, polywood, pressboard, hardboard, MDF and sandwich panels used in furniture, cabinetry, retail fixtures, and signage.
   • Thin-Sheet Metal & Enclosures – Secures electronic and electrical enclosures, HVAC panels, server racks and metal housings where access to the blind side is impossible.
   • Automotive & Transportation Interiors – Fastens trim, instrument panels, and plastic shrouds in buses, trains, boats and RVs without distorting delicate interior laminates.
   • General Industrial & Consumer Goods – Used in playground equipment, point-of-sale displays, medical device casings, retail gondolas and exhibition stands—anywhere a flush, strong thread insert is needed in thin or brittle substrates.
3. Effortless Installation & Operation
   • True Blind-Side Fitting – No need for backside access or jigs: insert is placed in a pre-drilled hole, a standard blind-rivet or nut-insert tool draws the mandrel to flare the petals, then snaps off cleanly—leaving a flush head.
   • Rapid, Repeatable Setting – Compatible with pneumatic, battery-powered, or manual setting tools; cycle times <2 s each make high-volume installations fast and consistent.
   • Universal Screw Compatibility – Accepts standard machine screws or bolts; once set, the insert acts like a captive nut, allowing easy screw-in/out cycles without additional nuts or washers.
   • Organized Assortment Kits – Available in plastic cases with labeled compartments covering common sizes (M4–M8, ¼-20, 5/16-18) for on-site convenience and minimal downtime.
4. Superior Quality & Long-Term Reliability
   • International Standards & Certification – Produced in ISO 9001–certified facilities to ISO 9001, DIN 7904 and ASTM F 826 tolerances, ensuring dimensional accuracy (±0.1 mm) and mechanical consistency.
   • Rigorous Testing & Traceability – Each lot is batch-tested for pull-out strength, shear load, and salt-spray corrosion (≥240 h); full heat-number traceability from raw bar to finished insert.
   • Vibration & Fatigue Resistance – The expanded petal design and high-clamp-load threads resist loosening under cyclic loads, temperature changes, and mechanical shock.
   • Regulatory & Environmental Compliance – RoHS- and REACH-compliant; free of hexavalent chromium and other hazardous substances, supporting sustainable manufacturing and safe end-use in consumer and industrial markets.
