Socket Head Cap Screws

What is Socket Head Cap Screws?

Socket Head Cap Screws (SHCS) are a type of fastener that is commonly used in machinery, electronics, and other industrial applications.

As the name suggests, SHCS have a cylindrical head with a socket for a hex key or Allen wrench to tighten or loosen them. They are also characterized by their fully threaded shank and are commonly made from alloy steel, stainless steel, or titanium.

SHCS are often used in applications where a low profile, high-strength fastener is required. Their design allows for easy access to the fastener head, making them ideal for tight spaces where a wrench or other tool may not fit. They are also known for their high tensile strength and resistance to vibration, making them a popular choice for applications where durability and stability are crucial.

Overall, SHCS are a versatile and reliable fastener option that is widely used in a variety of industrial and commercial applications.

Socket Head Cap Screws (SHCS) are fasteners that are designed to be used with a socket wrench or hex key to tighten or loosen them. They are commonly used in machinery, equipment, and automotive applications where a strong and reliable connection is needed.

Here are some common specifications for Socket Head Cap Screws:

1. Material: Socket Head Cap Screws can be made from a variety of materials, including alloy steel, stainless steel, and brass. The material used will depend on the application and the environment the screw will be used in.

2. Thread Size: The thread size of a Socket Head Cap Screw is measured in thread pitch and diameter. Common thread sizes include M3, M4, M5, M6, M8, M10, and M12.

3. Length: The length of a Socket Head Cap Screw is measured from the bottom of the head to the end of the threaded portion of the screw. Lengths can vary depending on the application, but common lengths range from 6mm to 100mm.

4. Head Type: The head of a Socket Head Cap Screw is typically a cylindrical shape with a flat top, but there are variations with rounded, flanged, or tapered heads. The head can also have knurling, which makes it easier to grip with a tool.

5. Drive Type: The drive type refers to the shape of the socket or hex key needed to turn the screw. Common drive types include hex socket (also called Allen socket), Torx, and square socket.

6. Grade: Socket Head Cap Screws are graded by their strength and are commonly classified using the ASTM (American Society for Testing and Materials) standards. The most common grades are 8.8, 10.9, and 12.9.

7. Finish: Socket Head Cap Screws can be finished with various coatings to protect against corrosion and improve appearance. Common finishes include black oxide, zinc plating, and passivation.

It's important to consult the manufacturer's specifications or a professional for guidance on selecting the appropriate Socket Head Cap Screws for your specific application.
