The DIN127B carbon steel black spring lock washer is a split ring washer designed to prevent loosening under vibration, conforming to DIN 127B standards. It is manufactured from carbon steel with a black oxide finish, providing a low-friction, non-reflective surface. The washer’s spring action is achieved through a precise helical cut and material thickness, allowing it to maintain tension when compressed between a nut and surface.
Material composition is standard low carbon steel, typically with 0.05% to 0.25% carbon content, suitable for cold forming. The black oxide finish is applied via chemical conversion, offering mild corrosion resistance and improved appearance over bare steel. The washer’s spring rate and deflection are determined by wire diameter and split width, with typical thicknesses ranging from 0.8 mm to 3.0 mm depending on size. Surface hardness is typically 35 to 45 HRC to ensure resilience without brittleness.
These washers are widely used in machinery, automotive assemblies, and industrial equipment where vibration resistance is critical. Buyers include manufacturers of pumps, conveyors, and power tools. Trade terms follow FOB Ningbo, with lead times of 7 to 15 working days. Packaging is in standard cartons of 36x24x16 cm or 36x24x12 cm, with Euro pallets available for bulk shipments. Custom finishes such as zinc or Geomet are listed as options but not standard.

Sourcing DIN127B Carbon Steel Black Spring Lock Washer from Ningbo Yongbiao International Business Co., Ltd - China Import Guide
Before ordering, verify the wire diameter, split width, and hardness of the washers with physical samples. Request a material certification confirming carbon steel grade and black oxide process. Confirm that dimensions align with DIN 127B tolerances, particularly for inner diameter, as deviations can prevent proper nut engagement.
Lead time is 7 to 15 working days, subject to order volume and finish availability. Confirm Incoterms are FOB Ningbo and that payment terms include a deposit for custom batches. Packaging is standard carton and Euro pallet, but specify if you require segregation by size or batch. Always request a packing list matching your warehouse logistics.
For quality control, inspect samples for consistent split width, absence of burrs, and uniform black oxide coverage. Test spring tension with a simple compression tool to ensure consistent force. Retain samples for comparison with future shipments. If used in safety-critical systems, consider a pre-shipment inspection by an independent agent.
