When it comes to fastening materials, there are various options available in the market. But among all of them, one of the most popular and widely-used fasteners is the Hex Head Screw. It is a type of bolt that has a hexagonal head shape at one end and a threaded cylindrical shank at the other.
Hex Head Screws are also called hex bolts or machine bolts. They come in different sizes, materials, and finishes, and are used in a variety of applications, from woodworking and construction to automotive and marine industries.
In this blog, we will provide you with a comprehensive guide about Hex Head Screws, including their types, sizes, materials, and uses.
Types of Hex Head Screws
Hex Head Screws come in different types, depending on their specific application and use. The most common types are:
1. Hex Cap Screws: These are the most common type of Hex Head Screws. They have a washer face under the head and are used in applications where a tight joint is required.
2. Tap Bolts: These are fully threaded Hex Head Screws that are used in materials where extra holding power is required, such as wood and soft metals.
3. Set Screws: These are partially threaded Hex Head Screws that are used to secure one object inside another object.
4. Shoulder Bolts: These have a shoulder or a larger diameter section under the head, which enables them to act as a shaft in bearings or bushings.
Sizes of Hex Head Screws
Hex Head Screws come in different sizes, ranging from small to large diameters and lengths. The size of Hex Head Screws is determined by three basic dimensions: thread diameter, thread pitch, and length.
The thread diameter is the thickness of the screw and is measured across the widest point of the threads. The thread pitch is the distance between the threads and is measured in threads per inch (TPI). The length is the distance from the end of the shank to the bottom of the head.
Materials of Hex Head Screws
Hex Head Screws are made of different materials, depending on their specific application and environment. The most common materials are:
1. Steel: Hex Head Screws made of steel are strong, durable, and resistant to corrosion. They come in different grades, such as 2, 5, and 8.
2. Stainless Steel: Hex Head Screws made of stainless steel are corrosion-resistant, making them ideal for use in marine and outdoor environments.
3. Titanium: Hex Head Screws made of titanium are lightweight, strong, and resistant to corrosion, making them ideal for use in aerospace and medical industries.
Uses of Hex Head Screws
Hex Head Screws are used in a variety of applications, from household repairs to industrial and construction projects. They are used to fasten two or more materials together tightly and securely. Some of the common uses of Hex Head Screws are:
1. Woodworking: Hex Head Screws are used in woodworking projects, such as furniture and cabinets. They provide a strong, secure joint and can be easily removed and replaced.
2. Automotive: Hex Head Screws are used in automotive applications, such as engine parts and suspension systems. They provide a strong, durable, and secure connection.
3. Construction: Hex Head Screws are used in construction projects, such as steel framing, drywall, and roofing. They provide a strong, reliable, and easy-to-install connection.
Conclusion
Hex Head Screws are a popular and essential fastener that is used in a variety of applications. They come in different types, sizes, and materials, providing a wide range of options for different environments and applications. Understanding the basics of Hex Head Screws can help you choose the right type, size, and material for your specific needs and ensure a strong and secure connection.
