Din127b Spring Lock Washers from Ningbo Steel Bolt Co., Ltd are manufactured to DIN 127B standards, available in carbon steel and stainless steel variants with surface treatments including hot dip galvanised, zinc plating, Dacromet, and plain finishes. Dimensions conform to standard DIN profiles for nominal diameters from M3 to M36, with thickness and outer diameter ratios matching the specification's mechanical requirements for axial load distribution and vibration resistance.
These washers are heat treated to achieve a hardness range of 35 to 45 HRC for carbon steel grades, ensuring consistent spring tension and resistance to deformation under repeated loading. Stainless steel versions, typically grade 304, offer corrosion resistance suitable for outdoor or humid environments. The surface treatments are applied to meet industrial durability expectations, not for cosmetic purposes. Zinc plating provides basic rust inhibition, while Dacromet delivers enhanced protection without hydrogen embrittlement risk.
These washers are commonly used in automotive, construction, and heavy machinery applications where bolted joints face dynamic loads. Buyers include OEM component manufacturers, maintenance contractors, and industrial distributors sourcing replacement hardware. Packaging is typically in bulk polybags or cartons of 1,000 to 5,000 pieces, with custom labeling available. Lead time and minimum order quantities must be confirmed directly with the supplier, as they vary by finish and volume.

Sourcing Din127b Spring Lock Washers from Ningbo Steel Bolt Co., Ltd - China Import Guide
Before ordering, verify the material grade, surface treatment specification, and hardness certification for each batch. Request a material test report for carbon steel washers showing tensile strength and hardness values. Confirm that surface treatments like Dacromet or zinc plating meet ISO 4042 or equivalent standards. Do not assume compliance based on supplier claims without documentation.
Lead time and Incoterms must be confirmed directly. Standard terms may be FOB Ningbo or EXW Zhenhai, but payment terms like T/T or L/C vary. Minimum order quantities are not stated and depend on finish and size. Buyers should clarify whether packaging is export-ready, including palletisation and moisture barriers for ocean freight. Request a shipping schedule with estimated departure dates.
Quality inspection should include dimensional checks using calipers, hardness testing with a Rockwell tester, and visual inspection for coating uniformity. For large orders, request a sample batch for destructive testing. Ensure the supplier provides a packing list with part numbers, quantities, and batch IDs. Retain samples for reference in case of claims or quality disputes.
