DIN9250 Stainless Steel Toothed Washer Non Slip Gasket-Double Sided Toothed Locking Flat Gasket

description

1. Dual-Tooth Grip & Vibration-Damping Performance
   • Precision-stamped to DIN 9250 in 18-8 (304) stainless steel, the 8.4 mm inner-diameter disk carries aggressive radial serrations on both faces; these teeth cut through paint or oxide films and embed into mating surfaces, locking the joint against slip without adding significant height.
   • The flat profile distributes load evenly while the bilateral teeth create micro-interference fits that absorb vibration energy and curb noise, making the washer ideal for shock-prone assemblies.
   • Black passivated finish offers extra glare reduction and blends with dark housings while maintaining the material’s inherent corrosion resistance from −200 °C up to +400 °C.
   • Retains ≥ 90 % of initial clamp force after 1 000 transverse-vibration cycles and keeps contact resistance below 15 mΩ, ensuring both mechanical security and electrical continuity where bonding is required.
2. Versatile, Cross-Industry Application Spectrum
   • Precision Equipment & Instrumentation: Prevents micro-slip on optical mounts, sensor plates, and calibration fixtures sensitive to positional drift.
   • Shock-Absorbing Machinery: Secures anti-vibration feet, pneumatic isolators, and rubber-in-shear mounts on compressors, laboratory shakers, and packaging lines.
   • Transportation & Mobility Devices: Locks seat-track brackets, dashboard clusters, and battery housings exposed to road shock or resonance.
   • Renewable-Energy & Electronics Enclosures: Maintains torque on inverter lids, junction boxes, and telecom racks where stainless integrity, EMI grounding, and low profile are critical.
3. Technician-Friendly, Time-Saving Handling
   • Flat, symmetric design needs no orientation; installers simply place and tighten—ideal for blind or overhead work and compatible with automated pick-and-place feeders.
   • Fits under standard M8 hex or socket heads without altering recommended torque values, eliminating recalculation and special tooling.
   • Minimal thickness (≈ 1 mm) allows easy retrofit into existing stack-ups without switching to longer fasteners or enlarging counterbores.
   • Delivered bulk, in resealable pouches, or tape-and-reel strips to suit field maintenance kits, bench stations, or high-speed robotic assembly cells.
4. Certified Quality & Long-Term Durability
   • 100 % optical inspection verifies tooth height ± 0.02 mm, concentricity ≤ 0.05 mm TIR, and flatness within 0.03 mm; Cp/Cpk ≥ 1.33 data support ISO 9001, IATF 16949, and AS 9100 quality systems.
   • Stress-relief tempering preserves spring temper for countless tighten/loosen cycles without tooth wear or work-hardening cracks.
   • Optional PTFE-free dry-film lubricant reduces installation torque scatter while preserving bite; low-outgassing variants meet clean-room and vacuum requirements.
   • Each lot is QR-coded for traceability to melt chemistry, passivation batch, and vibration test records, assuring confidence in aerospace, medical, and infrastructure applications.
