Nickel-Based K500 Monel Alloy Hex Bolt
Product Overview
Nickel-Based K500 Monel Alloy Hex Bolt is a high-strength, corrosion-resistant fastener widely used in demanding environments such as marine, chemical processing, and aerospace applications. Manufactured from the Monel K500 alloy—an age-hardenable version of Monel 400—this hex bolt combines the superior corrosion resistance of nickel-copper alloys with increased strength and hardness gained through titanium and aluminum additions during processing. Its durability and stability make it ideal for use in both high-pressure and highly corrosive environments.
Types and Classifications
Nickel-Based K500 Monel Alloy Hex Bolts come in a variety of forms to suit different engineering needs. The main types include:
- Fully Threaded Hex Bolts
- Partially Threaded Hex Bolts
- Heavy Hex Bolts
- Custom Head Designs (upon request)
Each variant can be manufactured with metric or imperial threading and in both coarse and fine thread pitch based on application requirements. Additionally, these hex bolts may come with full or partial shank, depending on load-bearing needs.

Materials and Manufacturing Process
Monel K500 is a highly durable nickel-copper alloy with enhanced strength due to precipitation hardening. It exhibits excellent resistance to saltwater, acids, and alkalines, making it highly suitable for corrosive settings.
Typical manufacturing process for Nickel-Based K500 Monel Alloy Hex Bolts:
Raw Material (Monel K500 Rods) → Cold Forging or Hot Forging → Precision Machining → Heat Treatment (Age Hardening) → Surface Treatment → 100% Quality Testing → Packaging
Not only is the material corrosion-resistant and heat-stable, but it also provides high tensile and yield strength properties, making it comparable to high-strength carbon steel with an added advantage of non-corrosive behavior.
Application Fields
Nickel-Based K500 Monel Alloy Hex Bolts are utilized in areas where mechanical stress combines with aggressive environmental exposure. Common application industries include:
- Automotive Manufacturing: Used in engine and exhaust systems.
- Construction Engineering: Especially in coastal or underground installations.
- Mechanical Equipment: High-performance machines demanding anti-corrosive bolts.
- Power & Energy: Including oil & gas, hydroelectric and nuclear facilities.
- Electronics & Appliances: For secure assembly in heat-prone areas.
