Sirius A4 316 Stainless Steel Spring Washers M4

The Sirius A4 316 Stainless Steel Spring Washer in M4 is well suited to light-duty fastening tasks in compact assemblies, including electrical enclosures, small brackets, cabinetry fixings, and instrumentation mounts. The M4 size offers a step up in clamping capacity from M3 while remaining compact enough for tight-access installations. Engineered from A4 grade 316 stainless steel, these washers are highly resistant to rust, oxidisation, and corrosion — performing reliably in wet, coastal, and chemically exposed settings. The split-ring design creates consistent spring tension that locks M4 fasteners in position, reducing the risk of loosening under vibration or movement. Features and Benefits: • A4 grade 316 stainless steel construction for lasting corrosion protection • Suitable for light-duty and precision fastening applications • Spring action effectively prevents vibration-induced fastener loosening • Appropriate for marine, outdoor, and chemical environments • Compatible with M4 stainless steel bolts and nuts • Conforms to DIN 127 standard spring washer profile
