Quantity
The Hexagon Socket Head Bolt, manufactured in Wuxi – one of China’s most established industrial fastener hubs – offers a reliable, high-performance fastening solution for critical bolting applications. Produced from ASTM A193 B16 material, a quenched-and-tempered chromium-molybdenum-vanadium alloy steel, this bolt delivers outstanding tensile strength, creep resistance, and thermal stability at operating temperatures up to 593°C (1100°F). The hexagonal socket drive, designed per ASME B18.3, enables precise torque control using a standard Allen key, ensuring uniform clamp load – a fundamental requirement for gasket-sealed joints and pressure-retaining systems.
Material & Performance Advantages
ASTM A193 B16 outperforms conventional B7 or B8 grades in high-temperature service, offering superior resistance to stress relaxation and thermal fatigue. The 1-1/2 inch diameter combined with a 120 mm overall length provides substantial thread engagement for large-bore flanges, heavy-wall valves, and turbine casings. Every bolt undergoes strict heat treatment, hardness testing, and dimensional verification to meet ASME B18.3 socket head geometry requirements – including under-head fillet radius and chamfer dimensions – ensuring consistent fit and fatigue life across production lots.

Key Application Scenarios
This Hexagon Socket Head Bolt is specifically recommended for:
- High-temperature flange connections in petrochemical refineries, steam generators, and heat exchangers, where gasket compression must remain stable under cyclic thermal loading.
- Pressure vessel manways and reactor nozzles requiring controlled bolting per ASME PCC-1 guidelines.
- Power generation equipment, including turbine housings and boiler access covers.
- Heavy industrial machinery with confined installation spaces, where socket-head tools offer better accessibility than traditional hex-head wrenches.

- Heavy industrial machinery with confined installation spaces, where socket-head tools offer better accessibility than traditional hex-head wrenches.
For bolted joints incorporating spiral-wound, kammprofile, or flexible graphite gaskets, this bolt’s stable clamp force directly minimizes gasket creep relaxation, extending seal life and reducing unplanned maintenance intervals.
Quality Control & Traceability
Sourced from Wuxi – a region renowned for its mature fastener supply chain and rigorous quality infrastructure – each lot is fully traceable from raw material heat number to final inspection.
