Fractional Size ASTM A194/SA194 2H Heavy Hex Nut with Clear Cr3 Zinc Plating
Fractional Size ASTM A194 / SA194 2H Heavy Hex Nut with Clear Cr3 Zinc Plating
Fractional Size ASTM A194 / SA194 2H Heavy Hex Nuts with Clear Cr3 Zinc Plating are engineered for high-strength fastening in demanding industrial, structural, and pressure system applications. Designed to meet ASTM A194 / SA194 Grade 2H specifications, these heavy hex nuts provide exceptional durability, precise thread engagement, and dependable clamping force for critical bolting assemblies.
The heavy hex configuration features a larger hex profile and thicker body than standard hex nuts. This design improves load distribution and increases thread engagement when paired with high-strength bolts or threaded studs. The result is a more secure connection capable of withstanding heavy loads, vibration, and extreme mechanical stress.
Clear Cr3 zinc plating enhances corrosion resistance while maintaining compliance with modern environmental standards. Chromium-3 coatings provide a protective barrier against rust and oxidation without the environmental concerns associated with older hexavalent chromium plating processes.
Key Features of ASTM A194 / SA194 2H Heavy Hex Nuts
ASTM A194 / SA194 Grade 2H heavy hex nuts are widely used in high-performance bolting systems that require strength, reliability, and consistent thread performance.
Heat-Treated Grade 2H Strength
Grade 2H heavy hex nuts are heat treated to achieve higher strength and hardness levels. This makes them ideal for use with high-strength bolts and studs in applications involving high pressure, elevated temperatures, or heavy mechanical loads.
Heavy Hex Design for Improved Load Distribution
The larger hex shape provides a wider bearing surface and thicker nut profile. This improves clamping force and ensures secure thread engagement, helping maintain joint integrity in demanding environments.
Clear Cr3 Zinc Plating for Corrosion Protection
Clear Cr3 zinc plating provides a bright finish while protecting the nut from corrosion and environmental exposure. This coating is commonly used in industrial applications where moderate corrosion resistance is required.
Common Applications for ASTM A194 2H Heavy Hex Nuts
Industrial Piping and Pressure Systems
These nuts are commonly used with threaded studs in flanges, valves, and pressure vessels where high-strength fastening is essential.
Structural and Mechanical Equipment
Heavy-duty machinery, fabrication assemblies, and steel structures rely on Grade 2H heavy hex nuts for reliable bolt tension and joint stability.
Manufacturing and Maintenance Applications
OEM equipment manufacturers and maintenance professionals use 2H heavy hex nuts for repairs and assemblies requiring strong, dependable fastening performance.
Fractional Size ASTM A194 / SA194 2H Heavy Hex Nuts with Clear Cr3 zinc plating provide a reliable fastening solution for industrial professionals who demand strength, durability, and corrosion resistance.
