Grade 5 Hex Nut with Plain Plating

High-Strength Fastening for Industrial and Mechanical Applications

A Grade 5 Hex Nut with plain plating is a dependable, high-strength fastening solution engineered for applications that demand durability, consistent performance, and secure load-bearing capability. Commonly used across industrial, automotive, and construction environments, these nuts are designed to pair with Grade 5 bolts to create reliable, long-lasting joints in medium- to high-stress assemblies.

Material and Strength Characteristics

Grade 5 hex nuts are manufactured from medium carbon steel and heat-treated to achieve enhanced mechanical strength. Produced to meet SAE J429 standards, they deliver a tensile strength of approximately 120,000 PSI, making them well suited for applications where higher clamping force and resistance to vibration are required. This balance of strength and toughness allows Grade 5 nuts to perform reliably under dynamic loads.

Plain Plating Finish

The plain plating finish provides a clean, uncoated steel surface without zinc or other protective coatings. While this finish offers minimal corrosion resistance, it is ideal for dry, indoor, or controlled environments where exposure to moisture and corrosive elements is limited. The absence of additional coatings ensures precise thread fit and smooth installation, making plain finish nuts a practical choice for internal assemblies.

Hex Head Design and Thread Compatibility

Featuring a standard six-sided hexagonal shape, Grade 5 hex nuts are easy to install and remove using common hand tools such as wrenches and sockets. Manufactured to ANSI/ASME B18.2.2 specifications, they provide consistent thread engagement and compatibility with matching fractional bolts. Common size ranges include 1/4 fractional through 1 fractional diameter, supporting a wide variety of fastening needs.

Common Applications

• Automotive assemblies and repairs

• Industrial machinery and equipment

• Structural and mechanical construction

• General manufacturing and maintenance

Reliable Performance at an Affordable Value

Grade 5 Hex Nuts with plain plating offer an excellent combination of strength, reliability, and cost efficiency. They are an ideal solution when corrosion resistance is not the primary concern but dependable fastening performance is critical. For medium- to high-load applications in controlled environments, these nuts remain a trusted choice across multiple industries.
