DIN127B SPRING WASHERS from Ningbo High Tensile Bolts Ltd. are produced to meet DIN 127B specifications, available in carbon steel and stainless steel with a broad range of surface finishes including hot dip galvanised, zinc plating in yellow, white, blue, and black, Geomet, Dacromet, and nickel plating. Sizes range from M12 to M100 and 1/2 inch to 4 inch, accommodating large-diameter bolt applications common in heavy industrial equipment.
Carbon steel washers undergo heat treatment to ensure spring elasticity, with hardness values aligned with industry norms for load-bearing fasteners. Stainless steel variants use grade 304 as standard, offering moderate corrosion resistance. Surface treatments like Geomet and Dacromet are applied for enhanced durability in corrosive environments, while plain finishes are used where coating interference with torque is a concern. The supplier does not specify coating thickness or salt spray ratings.
These washers are primarily used in structural steel assemblies, wind turbine foundations, mining machinery, and marine hardware where high clamping force and vibration resistance are critical. Buyers include engineering contractors, equipment assemblers, and maintenance suppliers sourcing for capital projects. Packaging is typically in bulk cartons, with custom quantities available. MOQ and lead time are not listed and must be confirmed directly with the supplier.

Verify the exact material grade and coating specification before ordering. Request material certifications for stainless steel (EN 10204 3.2) and coating test reports for Geomet, Dacromet, or PTFE finishes. Do not accept supplier claims without documentation. For large sizes (M80+), confirm that the washer can maintain spring tension under expected load conditions.
Incoterms are not specified; common terms are FOB Ningbo or EXW Zhenhai. Lead time depends on finish complexity and order volume. Payment terms such as T/T or L/C must be negotiated. Confirm packaging details: are cartons moisture-sealed? Are inner bags used? Request a shipping schedule with container loading dates if importing via sea freight.
Inspect incoming shipments for dimensional accuracy using calipers, check coating uniformity under magnification, and verify hardness with a portable Rockwell tester. For batches over 10,000 pieces, sample 5% for destructive testing. Ensure the packing list includes batch numbers and coating types. Retain samples for quality control records and warranty claims.
