Grade 5 USA Manufactured Hex Nut with Cr3 Plating

The Grade 5 USA Manufactured Hex Nut with Cr3 (Chromium Trioxide) plating is a high-performance fastener designed to provide superior strength, corrosion resistance, and reliability in demanding applications. Manufactured in the USA, these hex nuts meet strict quality standards, ensuring they are ideal for use in industries like automotive, construction, and heavy machinery.
 

Nut Specifications

  • Material: Grade 5 hex nuts are made from medium carbon steel, typically meeting the SAE J429 standard. This material provides a tensile strength of 120,000 PSI, making them suitable for medium to high-stress applications.
  • Dimensions: Available in various sizes, Grade 5 hex nuts typically range from 1/4 inch to 1 inch in diameter. These nuts are designed to fit bolts with corresponding threads, adhering to ANSI/ASME B18.2.2 specifications for accuracy and consistency.
  • Strength: Grade 5 hex nuts undergo a heat treatment process to ensure optimal hardness and strength. This process allows them to withstand vibration, torque, and pressure without compromising their integrity.
  • Finish: The hex nuts are finished with Cr3 (Chromium Trioxide) plating, which enhances their resistance to corrosion and improves their surface hardness, making them ideal for more demanding environments.

​Cr3 (Chromium Trioxide) Plating Specifications
  • Corrosion Resistance: Cr3 plating provides superior corrosion resistance compared to plain plating. It is particularly effective in protecting against rust and oxidation in mildly corrosive environments.
  • Environmental Benefits: Unlike traditional hex nuts with Hexavalent Chromium (Cr6) plating, Cr3 plating is more environmentally friendly and complies with the latest environmental regulations, such as RoHS and REACH.
  • Durability: The Cr3 plating creates a hard, durable surface that resists wear and scratches. It also enhances the overall lifespan of the fastener, making it more reliable over time.
  • Appearance: Cr3 plating gives the hex nuts a bright, aesthetically appealing finish, providing an added visual quality to the fastener.


Applications and Benefits

Grade 5 USA Manufactured Hex Nuts with Cr3 plating are perfect for applications that require a combination of strength and corrosion protection. These include automotive repairs, industrial equipment assembly, machinery, and construction projects. Their high durability and environmental compliance make them a trusted choice for industries that demand long-lasting, robust fastening solutions.
