Flanged Hex Head Bolt- Stainless Steel A2-DIN 6921

描述

1.Excellent Performance – Precision-forged from A2 / 304 austenitic stainless steel, these DIN 6921 hex-flange bolts combine good tensile strength (~70 ksi / 480 MPa) with outstanding resistance to water, food acids, mild chemicals and atmospheric corrosion. The built-in washer-style flange distributes clamping force evenly and resists bolt-head pull-through or surface galling.

2.Wide Application Range – Ideal for stainless sheet-metal assemblies, food-processing and pharmaceutical equipment, marine fittings, HVAC mounts, architectural façades, and light structural joints where both corrosion resistance and vibration security are required. Performs reliably from -196 °C up to +425 °C without loss of mechanical integrity.

3.Easy to Install – The integral flange eliminates separate washers, speeding assembly and ensuring accurate seating against oversized or slotted holes. ISO coarse-pitch threads roll on smoothly, while the six-sided head accepts any standard spanner or socket for quick, consistent torque application even in confined spaces.

4.Reliable Quality – Manufactured under ISO 9001 systems and fully compliant with DIN 6921 dimensional tolerances and ISO 3506-1 mechanical requirements. Each production lot is inspected for hardness, thread accuracy, flange concentricity and surface finish; 3.1 material certificates and full traceability are supplied on request, guaranteeing dependable, long-service performance.
