Material Brass Finish Nickel Plated Manufacturing Standard DIN 125 - Form A For Use With Thread Size M3 (3mm) Internal Diameter (ID) 3.2mm External Diameter (OD) 7mm External Diameter (OD) Tolerance +0/-0.36mm Thickness (T) 0.55mm Thickness (T) Tolerance +0/-0.1mm   Nickel-plated brass and plain brass are two metals that have many similarities in composition. Both are composed of copper and zinc but differ in their uses and applications. Knowing the difference between these metals is important when selecting hardware for projects or products. Let’s take a look at what sets nickel-plated brass and plain brass apart from each other. What is Nickel Plated Brass? Nickel-plated brass is a metal that has been electroplated with a layer of nickel. This layer helps create a protective coating on the surface of the metal and can help resist corrosion and tarnishing. It also gives the metal a polished look that may vary depending on the thickness of the coating. This type of metal is often used in applications where it will be exposed to moisture, such as plumbing fixtures or outdoor furniture. What is Plain Brass? Plain brass is composed of copper and zinc without any additional coatings or treatments applied to the surface. It’s commonly used for decorative purposes due to its bright gold colour, but it can also be used for functional applications such as electrical components or machine parts. Unlike nickel-plated brass, plain brass does not have added protection from corrosion, so it does require more maintenance to keep it looking shiny. Difference Between Nickel Plated Brass and Brass Nickel plated brass is more resistant to corrosion than brass. Nickel plated brass is more wear resistant than brass. Nickel plated brass is more heat resistant than brass. Nickel plated brass is more electrically conductive than brass. Nickel plated brass is more aesthetically pleasing than brass. Nickel plated brass is more expensive than brass. Conclusion: When selecting hardware for your project or product, it’s important to understand the differences between nickel-plated brass and plain brass before making your decision. Nickel-plated brass has a protective layer on its surface that helps resist corrosion, while plain brass does not have this added protection but may be more appropriate if you are looking for decorative elements with its bright gold colour. Consider how your project will be used when deciding which type of metal you should use for maximum durability and longevity.

A hexagon nut, often referred to as a hex nut, is a type of fastener with six flat sides and is designed to be used with a bolt or threaded rod to secure objects together.  Zinc Plated Steel means that the hexagon nuts are made of steel and have been coated or plated with a layer of zinc. Zinc plating provides corrosion resistance to the nuts and helps prevent them from rusting when exposed to moisture or environmental factors. It also gives them a shiny silver appearance. These hexagon nuts are commonly used in a wide range of applications, including construction, machinery, automotive, and various other industries where fastening and securing components are required. The DIN 934 standard ensures that these nuts meet specific size, thread pitch, and quality requirements, making them reliable and compatible with other standard fasteners.
