Professional Applications & Engineering Value

These 316 stainless steel flat washers deliver critical protection against galvanic corrosion and stress cracking in demanding industrial environments. The inch-system dimensions (0.156" ID x 0.312" OD) are precision-engineered to match No. 6 screw sizes, ensuring a snug fit that prevents loosening under vibration and thermal cycling. In applications like chemical processing equipment, marine hardware, and food machinery, the high molybdenum content in 316 stainless steel resists pitting from chlorides and acidic exposure, extending service life. The flat washer design evenly distributes clamp load, reducing surface damage and maintaining joint integrity. By integrating these RoHS 3 and REACH compliant washers, engineers address both performance needs and regulatory mandates for hazardous substance control.
