Professional Applications & Engineering Value

This M16 metric flat washer made from 316 stainless steel provides critical engineering solutions where corrosion and chemical exposure are major concerns. Its high-grade material effectively resists pitting and crevice corrosion in chloride-rich environments like marine, offshore, and chemical processing plants. The precise 17.4mm inner diameter ensures perfect fitment with M16 bolts, preventing misalignment and thread damage during assembly. With its 31.7mm outer diameter and substantial thickness range, it distributes clamping forces evenly across surfaces, protecting sensitive components from deformation and bolt head embedment. This ASME B18.22M compliant washer delivers consistent performance in structural applications, food processing equipment, and pharmaceutical machinery where REACH compliance and material traceability are mandatory requirements.
