• Precise dimensional fit with 0.156" ID and 0.281" OD ensures secure seating and uniform load distribution for No. 6 screws
• Consistent thickness range of 0.024-0.038" provides reliable spacing and vibration dampening in assemblies
• Environmentally responsible manufacturing with full compliance to RoHS 3 and REACH standards, supporting sustainable procurement
• Broad industrial compatibility for use in electronics, lightweight structures, and corrosion-prone environments
• Cost-effective performance by reducing galvanic corrosion risks when paired with compatible metals

Professional Applications & Engineering Value

These aluminum flat washers are engineered to address common industrial challenges such as corrosion in humid or chemical environments and the need for lightweight components in aerospace or automotive assemblies. The aluminum material offers excellent corrosion resistance without requiring additional plating, simplifying inventory and reducing total cost. With precise inch dimensions (0.156" ID, 0.281" OD) and a controlled thickness range, these washers ensure consistent clamping force and prevent loosening under vibration in No. 6 screw applications. Ideal for electrical enclosures, marine hardware, and light structural assemblies, they provide long-term reliability while meeting stringent environmental regulations.
