DIN127B Spring Washer
DIN127B spring washer is a widely used locking fastening component designed to provide elastic pressure and improve the stability of bolted connections. The DIN127B spring washer features a split ring structure that creates spring tension between the bolt, nut, and assembly surface, helping reduce loosening caused by vibration and dynamic loads.
Manufactured from spring steel, stainless steel, or other suitable materials, the DIN127B spring washer offers reliable elasticity, good fatigue resistance, and versatile application performance. It is commonly used in machinery, automotive components, electrical equipment, construction systems, and general industrial assemblies.

Product Overview
The DIN127B spring washer is engineered to maintain fastening force in threaded connections. Its curved split design produces axial spring pressure when compressed, helping improve joint stability during operation.
Compared with standard flat washers, the DIN127B spring washer provides additional elastic support and helps compensate for minor movement, vibration, and settling within bolted joints.
This washer is available in various materials and surface finishes to meet different application requirements, including general mechanical assemblies, corrosion-resistant environments, and outdoor fastening systems.
