There are several materials of nuts and some of the popular ones are:

● Zinc-Plated Steel: It is one of the popular and commonly used nut materials for general purpose applications, usually indoor. Depending on the type of manufacturing, the color of the nut may be bluish or yellowish tint. It is a low carbon steel with a Zinc coating that provides moderate corrosion resistance. They are very cheap to manufacture as well.

● Stainless Steel: One of the toughest nut materials with very good corrosion resistance. As a result, stainless steel nuts are often used in industries, automobiles, ships (and other marine equipment) and outdoor objects in general. They are slightly expensive than the Zinc plated counterparts.

● Chrome / Nickel Plated Steel: Although stainless steel already consists of chromium, additional Chrome and Nickel plating of steel further increases the corrosion resistance. The other benefit of this plating is the surface of the nut looks very shiny, smooth and polished.

● Hot-dipped Galvanized Steel: In this type, the steel is coated with even thicker layer of Zinc for increased corrosion resistance and thus making them suitable for outdoor use. Even the nuts and washers must be of the galvanized type for proper coupling.

● Brass / Bronze: These types of nuts have a natural resistance to corrosion as they are alloys of copper. They are generally expensive than other nut materials and as a result they are often used in arts and decorative pieces.

● Alloy Steel: The Alloy Steel contains additional elements other than iron and carbon such as manganese, nickel, chromium etc. The result is a nut with very good strength, corrosion resistance and wear resistance. It is often black in color due to additional black oxide coating.

Types Of Nuts

Nuts are available in a variety of shapes, sizes, materials, and thread patterns. While your selection of a nut is somewhat constrained by your choice of bolt—particularly in terms of size and threading—you still should select the nut head shape and material that is most suitable for your application.The types of nuts we stock include:

● Coupling nuts: A coupling nut is a longer, cylindrical nut that joins two male threads. This component can be used to add length to an installation.

● Flange nuts: Similarly to flange bolts, flange nuts feature a round flange that acts as an external washer, and allowing for a more even load distribution.

● Hex nuts: Hex nuts are hexagonally shaped. These nuts are extremely versatile but require a wrench for installation. The types of hex nuts we supply include finished hex, semi-finished hex, hex flange, hex jam, heavy hex, and slotted hex.

● Lock nuts: Lock nuts are available in a range of shapes and are used to secure other nuts and prevent them from loosening. Types of Lock nuts include All Metal Lock nuts with Top or Side locking features, Serrated Hex Flange, and Nylon Inserts.

● Slotted nuts: Slotted nuts are designed and constructed such that they can form a locking mechanism with a cotter pin or a safety wire.

● Square nuts: Square nuts are characterized by their square shape. This head shape increases the surface area of the fastener and the amount of friction it experiences, reducing the risk of it loosening.

● Wheel nuts: Wheel nuts are a broad category of nuts that are used in automotive wheel applications.

Additional nut types: The other nut types we can custom manufacture include cap, castle, conical, Keps, thumb, and wing.
