Professional Applications & Engineering Value

These aluminum flat washers are engineered to address common challenges in industrial fastening, such as surface damage, galvanic corrosion, and weight management. The aluminum material naturally resists corrosion, making these washers suitable for electronics, aerospace, and outdoor equipment where moisture exposure is a concern. With a 0.203" ID tailored for No. 10 screw size, they ensure a snug fit that minimizes vibration-induced loosening in dynamic assemblies. The flat washer design and 0.375" OD provide an enlarged bearing surface, effectively distributing clamp load to prevent damage to soft materials and maintain joint integrity. This combination of lightweight properties and precise inch-system dimensions supports efficient assembly processes while meeting stringent RoHS and REACH standards for environmentally conscious manufacturing.

Specification Summary & Compliance
