Grade 2 Hex Head Nut with Cr3 Plating

Reliable, Corrosion-Resistant Fastening for General Applications

A Grade 2 Hex Head Nut with Cr3 plating is a versatile and dependable fastener designed for standard-duty applications where moderate strength and corrosion resistance are required. Widely used across mechanical, automotive, construction, and maintenance industries, this hex nut delivers consistent performance, easy installation, and long-term reliability in non-critical fastening environments.

Material and Grade Specifications

Grade 2 hex head nuts are manufactured from carbon steel, offering a moderate tensile strength ideal for light- to medium-duty applications. As a standard-duty fastener, Grade 2 is commonly selected for assemblies that do not require high clamping force or extreme load resistance. These nuts are well-suited for everyday fastening needs where reliability and affordability are key.

Hex Shape and Thread Design

The six-sided hexagonal shape allows for easy tightening and removal using standard wrenches or sockets, ensuring secure engagement and efficient torque application. Internal threading is precision-cut to match corresponding bolt threads, creating a tight, dependable connection that resists loosening under normal operating conditions.

Cr3 (Trivalent Chromium) Plating Benefits

Cr3 plating provides enhanced corrosion resistance compared to plain, uncoated nuts. This environmentally friendly trivalent chromium finish helps protect against rust and oxidation in both indoor and light outdoor environments. Cr3 plating is widely favored for its balance of durability, appearance, and compliance with modern environmental standards, making it an excellent choice for applications where moderate corrosion protection is needed.

Available Sizes and Compatibility

Grade 2 Hex Head Nuts with Cr3 plating are available in a wide range of sizes, typically from 1/4 fractional to 1 fractional diameter, allowing compatibility with numerous bolt sizes and fastening systems.

Common Applications

• Automotive: Securing trim, brackets, and non-critical components

• Construction: Framing, decking, and general assembly tasks

• Machinery: Light equipment and mechanical assemblies

• DIY & Maintenance: Household repairs and general-purpose projects

Dependable Performance

With its combination of moderate strength, corrosion resistance, and ease of use, the Grade 2 Hex Head Nut with Cr3 plating is a reliable solution for everyday fastening needs. It offers an excellent balance of performance, durability, and value across a wide range of applications.
