M4 Stainless Steel Spring Washer DIN 127 A2
Description
The DIN 127 A2 M4 stainless steel spring washer is designed to maintain tension and prevent loosening in bolted joints subject to vibration or dynamic loads. Manufactured from A2 (AISI 304) stainless steel, this spring washer delivers corrosion resistance and durable performance in both indoor and outdoor environments. As a split (helical) lock washer, it provides a slight spring force when compressed, creating friction between the fastener and the surface it clamps. This helps reduce the risk of nuts and bolts loosening unintentionally, enhancing joint reliability in machinery, frames, metalwork and general fastening applications.
