Professional Applications & Engineering Value
These zinc-plated steel flat washers are engineered to address common industrial challenges such as corrosion, uneven load distribution, and fastener failure. The zinc plating provides a protective barrier against moisture and chemicals, significantly enhancing corrosion resistance in demanding environments like outdoor machinery, automotive assemblies, and electrical enclosures. With precise dimensions including a 0.172" inner diameter and 0.75" outer diameter, these washers ensure optimal fit for No. 8 screws, preventing misalignment and distributing clamp load evenly to reduce surface damage and extend joint integrity. This makes them essential for industrial applications requiring reliable, long-lasting mechanical fasteners that maintain performance under stress and vibration.
Specification Summary & Compliance
This flat washer features inch-system dimensions with an inner diameter of 0.172", outer diameter of 0.75", and thickness ranging from 0.043" to 0.051", designed specifically for No. 8 screw sizes. It adheres to standard manufacturing practices for consistent quality and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and suitability for various industrial and commercial uses.
