DIN125 Flat Washer

description

1. Corrosion-Resistant, Color-Customizable Performance
   • Stamped to DIN 125 Form A from heat-treated medium-carbon steel (≈ 200 HV), each washer delivers stable compressive strength under clamp loads up to 50 kN on common M10 assemblies.
   • A uniform ≥ 8 µm zinc layer sealed with trivalent passivation provides ≥ 120 h neutral-salt-spray protection (ISO 9227); clear, yellow, black, olive, rainbow or any RAL/Pantone top-coat can be specified for rapid visual coding without affecting tolerance.
   • Precision 90 ° faces and tight thickness control (± 0.05 mm on M4–M12) spread load evenly, cutting surface embedment by up to 60 % versus bolt head alone and guarding soft substrates from gouging.
   • Burr-free outside edges preserve paint, anodising and powder-coat films on mating components, extending service life in outdoor, automotive and industrial environments.
2. Broad, Cross-Industry Application Spectrum
   • Transportation & Powersports: Protects aluminium brackets, battery trays and steering-stem joints on passenger vehicles, e-bikes, motorcycles, ATVs and light utility trucks exposed to vibration and road splash.
   • Machinery, Robotics & Automation: Levels clamp forces on slotted rails, motor bases and sensor mounts, maintaining positional accuracy during high-cycle duty.
   • Construction, Renewable-Energy & Outdoor Fixtures: Separates dissimilar metals in solar-panel frames, HVAC mounts and wind-turbine covers, mitigating galvanic corrosion while colour-matched finishes simplify trade-discipline identification.
   • Agricultural, Marine & Fluid-Handling Systems: Fastens pump housings, deck hardware and fertiliser sprayer frames subjected to moisture, fertiliser splash and mild chemicals; duplex coatings available for > 500 h salt-spray performance.
3. Installer-Friendly, Time-Saving Handling
   • Generous 0.3 mm ID chamfer lets washers slide smoothly over studs, expediting assembly in blind, overhead or gloved operations.
   • Flat-lay geometry prevents wobble on magnetic sockets and pick-and-place nozzles, boosting production throughput by up to 15 %.
   • Supplied bulk-packed, in resealable field pouches or tape-and-reel strands, integrating seamlessly with manual benches, maintenance kits and automated feeders.
   • Laser-etched size identification (≥ M6) simplifies quick visual sorting without calipers, reducing kitting errors on multi-size workstations.
4. Verified Quality & Full Traceability
   • Every lot undergoes 100 % optical inspection for outer-edge burr height < 0.03 mm, thickness variation ≤ 0.02 mm per tray and hardness conformity per ISO 4042; statistical Cp/Cpk data archived for ISO 9001 and IATF 16949 compliance.
   • Surfaces are shot-blasted to Ra ≤ 1.6 µm before plating, lowering friction and easing future disassembly; optional powder-coat overlays exceed 1 000 h Q-SUN xenon colour-fast testing without altering dimensions.
   • Packaging bears QR-coded labels that link each washer to its melt lot, plating bath and inspection record, ensuring end-to-end supply-chain transparency for aerospace, medical and critical-infrastructure projects.
   • All materials comply with RoHS 3 and REACH regulations, and can be supplied with full PPAP Level 3 documentation on request.
