Sirius A4 316 Stainless Steel Spring Washers M5

The Sirius A4 316 Stainless Steel Spring Washer in M3 is the smallest size in this range, purpose-built for precision fastening in compact or lightweight assemblies. The M3 size is commonly used in electronics enclosures, small instrument housings, fine fabrication work, and miniature mechanical assemblies where space is at a premium but corrosion resistance cannot be compromised. Despite its small dimensions, this washer is manufactured to the same high standard as the rest of the range, using A4 grade 316 stainless steel for reliable protection against rust and corrosion in damp, marine, or chemically active environments. The split-ring profile delivers effective spring action to secure M3 fasteners against vibration-induced loosening. Features and Benefits: • A4 grade 316 stainless steel for corrosion resistance even in small-scale applications • Ideal for precision, electronic, or lightweight fastening assemblies • Split-ring spring action prevents loosening of M3 fasteners under vibration • Suitable for damp, marine, and chemical environments • Compatible with M3 stainless steel bolts and nuts • Conforms to DIN 127 standard spring washer profile
