Anti-Corrosion, Load-Distributing Performance
• Stamped to DIN 125 Form A from austenitic A2 (18-8/304) stainless steel, the washer offers ≥ 700 MPa tensile strength and retains ductility between −200 °C and +400 °C.
• Precise 90° faces and a controlled hardness of ≤ 200 HV prevent galling against paired fasteners while the 100 % burr-free OD protects painted or anodised surfaces.
• A bright, passivated finish continually regenerates its chromium-oxide layer, delivering long-term resistance to salt spray, de-icing chemicals, mild acids, food-grade detergents and outdoor humidity.
• Uniform thickness tolerance (± 0.05 mm on common M4–M12 sizes) spreads clamp load evenly, cutting surface embedment by up to 60 % compared with bare bolt heads.
宽,跨工业应用光谱
• Machinery, Robotics & Automation: Levels clamp forces on slotted mounting rails, motor bases and linear-guide carriages to maintain precision alignment.
• Transportation & Mobility: Protects aluminium chassis brackets, battery trays and brake-line clamps in passenger vehicles, e-bikes, railcars and light aircraft.
• Food-Processing, Pharmaceutical & Clean-Room Equipment: Stainless construction and smooth edges suit mixer guards, conveyor rails and sterile enclosures exposed to aggressive wash-downs.
• Renewable Energy, Marine & Outdoor Structures: Separates dissimilar metals on solar-panel frames, wind-turbine covers and deck hardware, reducing galvanic potential in chloride-rich atmospheres.
方便操作者、 节省时间处理
• Generous 0.3 mm chamfer on the ID allows washers to slide effortlessly over studs and metric screws, expediting assembly in blind or overhead positions.
• Flat-lay geometry eliminates wobble on magnetic sockets and automated pick-and-place nozzles, boosting line throughput by up to 15 %.
• Supplied bulk-packed, in resealable field pouches, or tape-and-reel strands, ensuring seamless integration with manual benches, maintenance kits and high-speed feeders.
• Laser-etched size ID (≥ M6) simplifies quick visual sorting without calipers, reducing kitting errors on multi-size workstations.
品质有保障，全程可追溯
• Lots undergo 100 % optical inspection for outer-edge burr height < 0.03 mm, thickness variation ≤ 0.02 mm within a tray and hardness conformance per ISO 3506-1; Cp/Cpk data archived for ISO 9001 and IATF 16949 records.
• Surfaces shot-blasted to Ra ≤ 1.6 µm prior to passivation, minimising friction and easing disassembly after long-term service.
• Optional electropolishing yields Ra ≤ 0.4 µm for hygienic or decorative requirements without altering dimensional tolerances.
• QR-coded carton labels trace every washer to its melt lot and inspection record, guaranteeing end-to-end supply-chain transparency for safety-critical infrastructure, medical devices and aerospace tooling.
