Professional Applications & Engineering Value
These square hole washers deliver critical engineering value by solving common industrial fastening challenges. The 18-8 Stainless Steel composition provides exceptional resistance to rust and corrosion, making them ideal for outdoor equipment, marine applications, and chemical processing facilities where moisture exposure is constant. The precisely engineered square hole design prevents rotation during assembly, ensuring secure fastening with No. 10 screws in vibrating machinery and high-stress applications. With consistent 0.028-0.034" thickness and 0.561" OD, these washers maintain uniform pressure distribution while the 0.253" inside width accommodates standard screw sizes perfectly. This combination of material excellence and dimensional precision eliminates loosening issues and extends service life in demanding industrial environments.
Specification Summary & Compliance
Manufactured to inch system standards with 0.561" outer diameter, 0.253" inside width, and controlled 0.028-0.034" thickness for No. 10 screw applications. These square hole washers comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet the latest international standards for hazardous substance restrictions and chemical safety in industrial components.
