• Precise dimensional fit with 0.192" ID and 0.375" OD, ensuring reliable alignment and load distribution for 3/16" rivets.
• Consistent thickness range of 0.055-0.065" provides uniform pressure distribution and reduces fastener loosening.
• Enhanced durability from steel material, offering reliable performance under mechanical stress and vibration.
• Global compliance assurance with RoHS 3 and REACH standards, meeting strict industrial safety and environmental regulations.
• Broad industrial compatibility for use in assembly, machinery, and construction where inch-system fasteners are specified.
• Cost-effective protection by preventing surface damage and galvanic corrosion between dissimilar metals.

Professional Applications & Engineering Value

These zinc-plated steel flat washers are engineered to address common industrial challenges such as corrosion-induced failure and uneven load distribution. The zinc plating provides a sacrificial layer that significantly enhances corrosion resistance, making them ideal for applications in manufacturing, outdoor equipment, and assembly lines exposed to moisture. Their precise 0.192" ID and 0.375" OD ensure a snug fit with 3/16" rivets, preventing misalignment and distributing clamp load effectively to protect sensitive surfaces. By maintaining consistent thickness tolerances, these washers reduce the risk of joint loosening under vibration, delivering reliable performance in mechanical fastening and structural assemblies where durability and compliance are critical.
