High-Grip, Corrosion-Guarded Locking Performance
• Precision-stamped from 65 Mn spring steel and tempered to HRC 39-50 (≈ 350–500 HV), the washer’s outward-facing serrations bite simultaneously into the fastener head and joint material, producing prevailing torque that cancels vibration-induced loosening without thread damage.
• A ≥ 8 µm electro-zinc layer sealed with trivalent passivation delivers ≥ 120 h neutral-salt-spray protection (ISO 9227); optional clear, yellow, black, olive, or custom RAL / Pantone powder top-coats push corrosion life past 1 000 h while providing instant visual coding.
• Tooth geometry—60° flank angle and 0.25–0.45 mm height (M3–M12 range)—generates up to 30 % higher break-loose torque than flat spring washers of equal diameter, yet adds only 0.3–0.9 mm to the clamp stack.
• Meets locking criteria of DIN 6797 Type A (external-tooth), maintaining bite after repeated tighten/loosen cycles and resisting temperatures from −50 °C to +300 °C.
Межотраслевой спектр Применение
• Electronics & Consumer Devices: Keeps heatsink clips, PCB shields, and motor housings tight where low profile, electrical grounding through tooth contact, and colour-coded identification are valuable.
• Automotive, Powersports & Mobility: Prevents back-off on body trim, lighting brackets, battery trays, and fairings subjected to road shock, engine vibration, and humidity.
• Machinery, Robotics & Automation: Locks sensor mounts, guard plates, and cable glands, preserving positional accuracy during high-cycle duty, rapid axis reversals, and start-stop impacts.
• Construction, DIY & Outdoor Equipment: Provides hidden anti-slip fastening for shelving rails, garden tools, HVAC housings, and solar-panel frames exposed to weather and mild chemicals.
Установщик-дружественный, экономящий время
• Symmetric external serrations self-center under screw or nut faces, eliminating the alignment concerns of wedge-lock pairs or split pins and speeding overhead or blind installation—even with gloved hands.
• Flat-lay geometry prevents wobble on magnetic sockets and pick-and-place nozzles, improving automated feed reliability and boosting manual throughput.
• Supplied bulk-packed, in resealable field pouches, or on tape-and-reel strands for seamless integration with maintenance kits, bench stations, and high-speed assembly lines.
• Optional laser-etched size code (≥ M4) enables quick visual sorting, reducing kitting errors in multi-size work cells.
Доказанное качество и долгосрочная долговечность
• 100 % optical inspection verifies tooth height ± 0.02 mm, concentricity ≤ 0.05 mm TIR, and hardness per ISO 16228; Cp/Cpk data archived for ISO 9001 and IATF 16949 compliance.
• Stress-relief tempering minimises hydrogen embrittlement risk and preserves high spring modulus for enduring bite through multiple service cycles.
• Duplex-coated variants (zinc + epoxy powder) pass 1 000-h Q-SUN xenon exposure without flaking or colour shift, supporting long-term outdoor or chemical-plant use.
• QR-coded carton labels trace every washer lot to melt chemistry, plating batch, and inspection record, ensuring full transparency for safety-critical projects in infrastructure, aerospace, and medical equipment.
