DIN6921 Flange Bolts
DIN6921 flange bolts from Ningbo Beilun Milfast Metalworks Co. Ltd are metric fasteners with a 12-point hex flange head and integrated washer surface, designed for high-torque applications where load distribution is critical. Available in sizes M6 through M20, these bolts are manufactured in stainless steel grades A2-70 (304) and A4-80 (316), conforming to ISO 4161 standards. The flange reduces the need for separate washers and improves clamping stability in vibration-prone environments.
The material composition follows standard austenitic stainless steel specifications: 304 contains 18% chromium and 8% nickel, while 316 adds 2-3% molybdenum for enhanced corrosion resistance in marine or chemical settings. Surface finishes include plain, black oxide, and zinc plating, though the supplier's data confirms only stainless steel variants. These bolts are not hardened through heat treatment but achieve their strength through cold forming and material selection.
These fasteners are commonly purchased by OEM manufacturers in automotive, industrial machinery, and structural assembly sectors. Buyers typically order in bulk quantities for maintenance spares or production lines. Packaging is in cartons with plastic bag liners, suitable for export. Trade terms are negotiable but commonly FOB Ningbo or CIF destination ports. MOQ and lead time must be confirmed directly with the supplier.

Sourcing DIN6921 Flange Bolts from Ningbo Beilun Milfast Metalworks Co. Ltd - China Import Guide
Before ordering DIN6921 flange bolts from Ningbo Beilun Milfast Metalworks Co. Ltd, verify the material grade certification for each batch. Request a mill test report (MTR) showing chemical composition for 304 or 316 stainless, and confirm the mechanical properties match A2-70 or A4-80. Do not accept generic statements like 'stainless steel' without grade specification. Ensure the supplier can provide traceability from raw material to finished product.
Logistics are typically FOB Ningbo Port, with lead times around 20 to 30 days for bulk orders. Packaging is in cartons with plastic liners, but palletization and labeling must be confirmed. Incoterms like CIF or DDP are negotiable, but buyers should clarify who handles customs clearance and import duties. Payment terms are usually 30% advance and 70% against shipping documents. Confirm exact lead time with the supplier, as it is not stated in the listing.
Quality checks should include dimensional verification of flange diameter, thread pitch, and bolt length using calibrated gauges. Perform a salt spray test on sample batches if corrosion resistance is critical. Request a certificate of conformity and batch-specific hardness reports. Ensure packaging is labeled with material grade, size, quantity, and supplier code. Avoid accepting shipments without documentation - this is a common risk with suppliers lacking public certifications.
