Grade 5 USA Manufactured Hex Nut with Cr3 Plating

American-Made Strength with Enhanced Corrosion Protection

The Grade 5 USA Manufactured Hex Nut with Cr3 Plating is a high-performance fastening solution engineered for strength, durability, and long-term reliability. Proudly manufactured in the USA, these hex nuts are produced to exacting industry standards, making them a trusted choice for automotive, construction, industrial, and machinery applications where consistent performance matters.

Made from medium carbon steel and heat-treated to meet SAE J429 Grade 5 requirements, these nuts deliver a tensile strength of approximately 120,000 PSI. This makes them well-suited for medium to high-stress applications that demand dependable clamping force and resistance to vibration, torque, and mechanical load.

Nut Specifications and Construction

Material: Medium carbon steel, SAE J429 Grade 5
Manufacturing Origin: USA manufactured
Strength: Heat-treated for high tensile and shear strength
Sizes: Commonly available from 1/4″ to 1″ fractional diameters
Thread Standard: ANSI/ASME B18.2.2 compliant
Finish: Cr3 (Trivalent Chromium) plated

The classic six-sided hex design allows for easy installation using standard wrenches or sockets, ensuring secure fastening and consistent torque during assembly.

Benefits of Cr3 (Trivalent Chromium) Plating

Cr3 plating provides an ideal balance between corrosion resistance and environmental responsibility. Compared to plain finish hardware, Cr3-plated hex nuts offer improved protection against rust and oxidation in mildly corrosive environments.

Corrosion Resistance: Helps protect against moisture and environmental exposure
Environmentally Friendly: RoHS and REACH compliant, safer alternative to Cr6 plating
Durable Surface: Enhanced wear resistance and longer fastener life
Attractive Finish: Bright, clean appearance suitable for visible assemblies

Applications and Typical Uses

Grade 5 hex nuts with Cr3 plating are commonly used in:

Automotive and truck assembly
Construction and structural fastening
Industrial machinery and equipment
Agricultural and material handling systems
General manufacturing and maintenance
