Sirius A4 316 Stainless Steel Spring Washers M12

The Sirius A4 316 Stainless Steel Spring Washer in M12 is a popular and robust choice for heavier fastening applications, including structural connections, pipework flanges, marine hardware, and industrial equipment assemblies. The M12 size provides an increased load-bearing surface and greater spring force compared to smaller variants, making it ideal where stronger clamping action is required. Constructed from A4 grade 316 stainless steel, these washers offer excellent resistance to corrosion in saltwater, chemical, and high-humidity environments. The characteristic split-ring profile generates a spring action that maintains consistent clamp load, guarding against fastener loosening caused by vibration or temperature fluctuations. Features and Benefits: • A4 grade 316 stainless steel for outstanding corrosion and rust resistance • Increased spring force suitable for heavier-duty bolted joints • Prevents fastener loosening under vibration and thermal cycling • Suitable for marine, offshore, and chemical processing environments • Compatible with M12 stainless steel bolts and nuts • Conforms to DIN 127 standard spring washer profile
