ASME B18.3 Hexagon Socket Countersunk Head Screws (ASTM B865 K500)
Shaanxi Flourish Industrial Co., Ltd. is a leading global supplier of high-performance fasteners, specializing in manufacturing ASME B18.3 hexagon socket countersunk head screws crafted from ASTM B865 Monel K500 alloy. These screws provide ultimate reliability for extreme industrial applications, combining ASME's rigorous dimensional precision with the exceptional strength and corrosion resistance of Monel K500. Backed by ISO-certified production and full material traceability, we deliver custom-engineered solutions that meet even the most demanding project requirements.
Product Overview
Our hexagon socket countersunk head screws adhere strictly to ASME B18.3 standards, featuring a flush-mount design that eliminates protrusions for smooth surfaces and enhanced safety. The Monel K500 alloy (UNS N05500, Werkstoff Nr. 2.4375) is a precipitation-hardened nickel-copper alloy, reinforced with aluminum and titanium to deliver three times the yield strength of conventional Monel 400. This unique combination makes the screws ideal for applications requiring both high load-bearing capacity and resistance to harsh corrosives.

Material Properties (ASTM B865 K500)
Monel K500's exceptional performance stems from its optimized composition and mechanical characteristics:
Chemical Composition (min/max):
- Ni (63.0%), Cu (27.0-33.0%), Al (2.3-3.15%), Ti (0.35-0.85%), Fe (≤2.0%), C (≤0.25%)
Mechanical Performance:
- Tensile Strength: 1100 MPa (160,000 psi)
- Yield Strength (0.2% offset): 790 MPa (115,000 psi)
- Elongation: ≥20%
- Density: 8.44 g/cm³
- Melting Point: 1350°C (2460°F)
Corrosion Resistance:
Withstands seawater, acidic/alkaline media, and H₂S environments (corrosion rate <0.25mm/a), passing ASTM G28 A.
Core Advantages
- Superior Durability: Precipitation-hardened alloy resists deformation under high pressure and temperature fluctuations.
- Corrosion Immunity: Outperforms stainless steel in marine and chemical processing—ideal for offshore platforms and reactors.
- Precision Fit: ASME B18.3 compliance ensures consistent dimensions for seamless integration with existing systems.
- Versatile Machinability: Easy to weld, drill, and customize, supporting complex assembly requirements.
Applications
Our screws are trusted in industries where failure is not an option:
- Offshore: Pump shafts, valve components, and subsea equipment
- Chemical: Reactors, processing tanks, and pipeline fasteners
- Aerospace: High-stress structural assemblies
- Marine: Hull fittings and seawater-handling systems
Quality & Logistics
- Quality Control: Raw material traceability, NACE MR0175/ISO 15156 compliance, and batch testing
- Packaging: Waterproof polybags + plywood crates for corrosion protection during transit
- Lead Time: 10-45 days (expedited options available)
- Payment Terms: L/C, T/T, Western Union
