Hex bolts are common fasteners used in construction, manufacturing, and various industrial applications. They are also referred to as hex head bolts and have a six-sided head design, which provides excellent grip and torque during installation. Hex bolts are used for making secure joints in structural and non-structural applications. At Canada Bolts, we offer a wide range of collections of hex bolts like full-thread bolts and partially threaded bolts to meet the various needs of everyone.

What is a Hex Bolt?

A hex bolt is a fastener that has a six-shaped head and threaded shank. They work with nuts or in pre-threaded holes to give a secure and durable connection. These bolts are available in various materials such as stainless steel, zinc-plated steel, and more. 

Key Dimensions of Hex Bolts

Hex bolts have various dimensions and properties and are used and important for different applications. Here's a detailed look at these dimensions:

Diameter

The diameter refers to the width of the bolt's shaft, measured with its thinnest point, excluding the head. It determines the bolt's strength and load capacity. Diameters range from 1/4 inch to 2 inches and from M2.5 to M100. It is important to know the bolt's strength for the application. Larger diameters provide greater strength and are for heavy-duty applications.

Length

The length of a hex bolt is measured from the underside of the bolt head to the tip of the bolt. It ensures the bolt passes through materials and allows for full connection with the nut or internal threads. They vary from 6mm to 250mm metric. You have to choose the right length for a secure connection. 

Grade/Class

The grade or class of a hex bolt shows its strength and hardness. If you choose the right grade/class the bolt can withstand the stress and load conditions without failure. Higher grades are used in more demanding applications such as automotive, aerospace, and heavy machinery. 

Thread

The thread of a hex bolt has helical ridges that allow it to be screwed into a nut or a tapped hole. There are various thread types:

  • Fully Threaded: The entire length of the bolt is threaded in full-threaded and used for applications where threading is required to secure materials.

  • Partially Threaded: Partially threaded bolts have a smooth section at the base of the shaft for easier assembly with nuts or to ensure the bolt can seat properly against a surface.

If you fix the thread properly the bolt will stay secure under load, preventing loosening and ensuring proper assembly strength.

Finishing

The finishing of a hex bolt involves coating or surface treatments to enhance the bolt's durability and corrosion resistance. They include zinc plating, stainless steel, and more. You should finish according to the industry the bolt will be used. 

Sizes of Hex bolts

Hex bolts are available in a wide range of sizes and they vary from M2.5 to M14. They are used in industries because of their precision and compatibility with different materials. Here are the different sizes of hex bolts at Canada Bolts:

  • M2.5 Hex Bolt: It is used in electronic devices, small machinery, and precision assemblies. These bolts are used in applications where compact size and reduced weight are essential.

  • M3 Hex Bolt: M3 bolts are used in electronics and automotive components for lightweight fastenings that require average strength.

  • M4 Hex Bolt: They are used for fixing furniture, small machinery, and electrical boxes because they give a good balance between strength and size.

  • M5 Hex Bolt: They are used in electronics, small appliances, and home repairs and are commonly found in DIY projects.

  • M6 Hex Bolt: You can use these bolts for light to medium-duty structural applications, automotive, and machinery for construction and manufacturing.

  • M8 Hex Bolt: They are used in building construction, structural frameworks, and heavy machinery because they provide high strength in heavy applications.

  • M10 Hex Bolt: They are used in bridges, heavy equipment, and industrial machines because they need high strength.

  • M12 Hex Bolt: They are used in heavy construction, infrastructure projects, and large machinery because they are durable and have resistance to high loads.

  • M14 Hex Bolt: They are commonly used in the construction of bridges, heavy-duty machinery, and large-scale building projects because they provide secure connections in demanding environments.

How to Choose the Right Hex Bolt?

Choosing the right hex bolt is essential to fix it successfully. Here’s how to choose the hex:

Determine Load and Stress

Choose bolts with lower grades for light-stress applications like furniture or small machinery and high-grade bolts for applications industries like construction, automotive, or machinery.

Size 

Check the diameter of bolts that matches the size of the holes and check it is long enough to pass through the materials being fastened and connected with the nut or threaded hole.

Thread Type

  • Fully Threaded Bolts: These bolts are used and are fully threaded where the entire length needs to be threaded and give better-holding power.

  • Partially Threaded Bolts: They are used for applications where the bolt only needs to pass through one material and be secured by the nut, allowing space for proper seating.

Finishing Considerations

  • Zinc Plating: They give good corrosion resistance and are used for indoor applications and general-purpose use.

  • Stainless Steel: Stainless steel bolts provide excellent corrosion resistance and durability for applications in harsh environments such as marine, outdoor, and industrial settings.

FAQs for Buying Bolts Online

1. What is the difference between hex bolts and hex screws?

Hex bolts need a nut for installation and hex screws are fully threaded and self-tapped for direct installation into materials.

2. What are full-thread bolts used for?

Full-thread bolts are used in applications that need maximum grip strength for fastening components in machinery or heavy-duty equipment.

3. Are hex head bolts suitable for outdoor use?

Yes, stainless steel or zinc-plated bolts that are corrosion-resistant and perfect for outdoor environments.

4. What sizes of hex bolts are available?

Hex bolts come in a variety of sizes, from small diameters for light-duty applications to larger sizes for heavy-duty tasks.

5. How do I determine the correct bolt length?

You should measure the combined thickness of the materials that will be fastened and add the thickness of the nut and washer to determine the bolt length.

6. Can hexagon bolts be reused?

Hexagon bolts can be reused if they are undamaged. However, you should check for signs of wear or thread stripping before reuse.
