Product Description
Metric A4 marine grade stainless steel square section spring washers to DIN 7980. These spring lock washers are designed for use with metric bolts, screws and nuts where a square section washer is required.
Manufactured from A4 stainless steel, these washers offer improved corrosion resistance compared with standard zinc plated or A2 stainless washers, making them suitable for marine, outdoor, coastal, automotive, engineering and general stainless steel fastening applications.
The split spring design helps maintain tension in the assembly and provides resistance against loosening in general fastening use. Available in metric sizes from M2 to M30, these DIN 7980 square section spring washers are supplied in small and bulk pack sizes.
