Product Description
M4 - Square Section Spring Washer DIN 7980 - A4 Stainless Steel | Vital Parts
Our Square Section Spring Washers DIN 7980 are designed to provide enhanced locking capabilities in bolted joints, especially where short bolts are used and thrust or vibration is present. These washers compress during fastening to apply a spring-like force that counteracts loosening, making them an ideal choice for dynamic applications where joint integrity is critical.
This product has a square cross-section and is manufactured to the DIN 7980 standard using high-grade A4 (316 Marine Grade) stainless steel. This ensures excellent resistance to corrosion, wear, and fatigue under medium to heavy loads. Available in metric sizes from M3 to M30, these washers are perfect for industrial, automotive, marine, and engineering use.
What are Square Section Spring Washers?
Square Section Spring Washers, often referred to as Split Washers or Spring Lock Washers, are mechanical fastener accessories designed to prevent loosening in assemblies subject to thrust or vibration. DIN 7980 washers feature a split ring with a square profile, which produces high spring tension when compressed. This helps maintain the clamping force of bolts or screws, even in challenging environments, thereby improving the longevity and safety of the connection.
