The Din7991 hexagon socket countersunk screw from Ningbo Beilun Milfast Metalworks Co. Ltd is manufactured to DIN 7991 standards with head angles of 90 degrees and flat countersunk profiles designed for flush mounting. Available sizes range from M2 to M20, with material options including stainless steel (A2, A4), carbon steel, and aluminium. The screws feature precision-machined hexagon sockets for torque transmission and are produced using cold heading and thread rolling processes consistent with industrial fastener norms.
Material variants include stainless steel grades A2 and A4 for corrosion resistance, carbon steel with surface finishes such as black oxide, zinc plating, blue dye, and cadmium plating for environmental or aesthetic performance. These finishes are applied after heat treatment to maintain mechanical integrity. The screws meet standard tolerances for thread pitch and head height per DIN 7991, with typical dimensional deviations within ±0.05 mm for diameter and ±0.1 mm for length. Surface treatments are tested for salt spray resistance where specified, though exact duration is not confirmed by the supplier.
These screws are commonly used in aerospace, automotive assembly, medical devices, and precision machinery where low-profile fastening and high torque control are required. Buyers include OEM manufacturers in Europe and North America sourcing for internal assemblies. Packaging is provided in cartons and sealed plastic bags, suitable for bulk handling. Trade terms are not listed; buyers must confirm minimum order quantities, lead times, and Incoterms directly with the supplier.

Sourcing Din7991 Hexagon Socket Countersunk Screw from Ningbo Beilun Milfast Metalworks Co. Ltd - China Import Guide
Before ordering, verify the exact material grade (e.g., A2 vs A4 stainless steel), surface finish type, and dimensional tolerances with the supplier. Request sample parts for fit and function testing, especially if the screws will be used in high-vibration or high-corrosion environments. Confirm that the finish meets any industry-specific standards such as RoHS or REACH if applicable.
Lead time and Incoterms are not stated on the listing. Buyers must confirm whether FOB Ningbo or EXW terms apply, and whether palletization is included. Standard carton dimensions are not specified; request packaging diagrams to ensure compatibility with your warehouse systems. Payment terms such as T/T or LC should be negotiated directly, as no defaults are provided.
Conduct a pre-shipment inspection for thread integrity, head chamfer accuracy, and finish uniformity. Use a thread gauge to verify pitch and minor diameter. Check for surface defects like cracks or plating bubbles under magnification. Request a packing list with batch numbers and material certifications if traceability is required for compliance audits.
