Professional Applications & Engineering Value
These 316 stainless steel flat washers deliver exceptional engineering value in demanding applications where corrosion resistance is critical. The marine-grade 316 stainless steel composition provides superior protection against saltwater, chemicals, and industrial atmospheres that would degrade ordinary washers. With their precise 1/2" inner diameter and substantial 1.625" outer diameter, these flat washers effectively distribute clamping force over a wider area, preventing surface damage and maintaining joint integrity. The controlled 0.060-0.090" thickness range ensures consistent performance in assembly operations, making them ideal for marine equipment, chemical processing facilities, and coastal infrastructure where reliability cannot be compromised.
Specification Summary & Compliance
This flat washer features inch system dimensions with 0.531" inner diameter, 1.625" outer diameter, and 0.060-0.090" thickness range, specifically engineered for 1/2" screw applications. Manufactured from premium 316 stainless steel, these washers meet RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) standards (updated 06/14/2023, 235 SVHC), ensuring environmental safety and regulatory adherence for industrial and international markets.
