Socket Head Cap Screw-304 Stainless Steel -Allen Socket Hex Drive Bolt

描述

1.Robust Performance – Manufactured from 18-8 (A2/304) stainless steel, these socket head cap screws deliver ≈ 120 ksi / 830 MPa tensile strength after cold-working—about twice that of standard hex screws—while resisting rain-water, salt-spray, food acids, and most industrial chemicals across a service window of −196 °C to +425 °C. The tall, cylindrical head supplies ample bearing area and lets the screw be tightened to high, repeatable preload without head stripping.

2.Broad Application Range – The compact head and full-depth internal hex make these screws the preferred choice for machinery frames, robotics joints, pneumatic manifolds, 3-D printers, automotive assemblies, marine hardware, medical devices, and anywhere confined clearances or aesthetic flushness preclude traditional hex bolts.

3.Easy to Operate – Deep hex-socket drive accepts common Allen keys or power bits, enabling one-handed installation in tight recesses while preventing tool slippage (cam-out). Precision-rolled threads start easily, run smoothly, and reduce galling; chamfered tips guide the screw into tapped holes without cross-threading for faster line-side assembly.

4.Proven Quality Assurance – Produced under ISO 9001 systems and compliant with ASME B18.3 / ISO 4762 dimensions and ISO 3506-1 mechanical requirements. Each batch is thread-gauge verified, hardness and tensile tested, magnetic-particle inspected, passivated for maximum corrosion resistance, and laser-etched with heat-lot codes. Full EN 10204 3.1 material certificates provide complete traceability, ensuring long-service reliability in demanding environments.
