Socket Low Head Cap Screw DIN 6912-18-8 304 Stainless Steel Hex Socket Cup Bolt

描述

1.High-Performance, Low-Profile – Precision-machined from work-hardened 18-8 / 304 stainless steel, these low-head socket cap screws (DIN 6912 style) combine ≈ 90 ksi / 620 MPa tensile strength with outstanding resistance to rain-water, salt-spray, food acids, and most industrial chemicals from −196 °C to +425 °C. The reduced head height saves up to 40 % clearance versus standard socket caps, enabling compact designs without sacrificing clamp load.

2.Broad Application Range – Perfect for tight-space assemblies such as robotics joints, 3-D-printer frames, electronics heat-sinks, slimline machinery guards, bicycle components, marine hardware, and architectural fixtures—anywhere a flush, snag-free head and long-term corrosion protection are essential.

3.Easy to Operate – Deep internal hex recess accepts standard Allen keys or power bits, delivering high torque without cam-out even in cramped recesses. Rolled metric or UNC threads run smoothly, while chamfered tips and relieved under-head fillets prevent cross-threading and stress risers, speeding installation on the production line.

4.Verified Quality – Produced under ISO 9001 systems and fully compliant with DIN 6912 dimensions and ISO 3506-1 mechanical requirements. Every batch is thread-gauge checked, hardness and tensile tested, passivated for maximum corrosion resistance, and laser-etched with heat-lot codes. EN 10204 3.1 material certificates provide full traceability, ensuring consistently high quality and dependable service life.
