Product Description

Wholesale round head hex socket screws are a type of fastener used in a variety of industries, especially in construction, manufacturing, and engineering applications. The term "round head" refers to the rounded top of the screw, which has a smooth appearance when installed. The "hex" part means that there is a hexagonal groove on the end of the screw, which can be used with a hexagonal wrench or socket wrench.

Key features of round head hex socket screws include:

1. **Thread Type**: These screws are available in different thread types, such as UNC (unified coarse thread), UNF (unified fine thread), and metric threads. The choice depends on the material being fastened and the required strength of the connection.

2. **Head Style**: The round head design features a rounded top, which can be aesthetically pleasing in certain applications. This style also helps prevent damage to the surface when driving the screw in or out.

3. **Socket Size**: The hex socket size corresponds to the tool required to drive the screw in. Common sizes include #2, #4, #6, etc., depending on the diameter of the screw.

4. **Material**: These screws are typically made from materials such as steel, stainless steel, brass, or aluminum, each of which offers different durability, corrosion resistance, and cost-effectiveness.

5. **Finish**: Screws may have a variety of finishes, such as plain, zinc-plated, nickel-plated, black oxide, or stainless steel finishes, which not only affects their appearance, but also corrosion resistance and compatibility with other materials.

6. **Size**: Screw sizes range from small (e.g., M2) to large (e.g., M16), depending on the requirements of the application.

7. **Quantity**: When buying wholesale, you will typically purchase these screws in bulk, which is more cost-effective than purchasing them individually.

When selecting a round head hex socket screw, consider factors such as load capacity, environmental conditions, and specific application requirements. It is also important to match the screw size and thread type to the appropriate component to ensure a safe and effective assembly.
