Bolts are essential components in many DIY projects, and they come in different types, including different bolt heads. Bolt heads enhance the appearance of your projects and play a critical role in how you use the bolts. This blog post will explore the different types of bolt heads, their uses, and why you need to know them.
Types of Bolt Heads
Flat Bolt Head
This bolt head is flat on the top and bottom, with no additional features. It is mainly used in areas with limited clearance, such as when working with thin and fragile materials, and provides a neater finish.
Oval Bolt Head
The oval bolt head has a rounded top and tapered sides, resembling an egg. This head is useful when you need to minimize the risk of snagging or damaging the material being joined and has a lower profile than the hex bolt head.
Pan Bolt Head
The pan bolt head has a flat bottom and slightly curved top, with a cone-shaped underside that widens as it approaches the shank. This type of bolt head is ideal for fastening metal materials that need a smooth surface and an increased bearing surface.
Truss Bolt Head
This bolt head features a low profile and a wide diameter, with a rounded top and flat underside. The truss bolt head is perfect for fastening materials to a curved surface, thanks to its wide diameter that distributes the load evenly.
Round Bolt Head
The round bolt head features a cylindrical shape with a flat top and bottom. It is often used in decorative applications, which lend a smooth, rounded appearance to the finished project.
Hex Bolt Head
This is the most common type of bolt head, recognizable by its six-sided shape. The hex bolt head is versatile and can be used in various applications, including automotive, construction, and DIY projects.
Hex Washer Bolt Head
This bolt head features a washer fused to the hex head to increase the bearing surface and ensure safety. It is ideal for use in materials that need large holes.
Slotted Hex Washer Bolt Head
This bolt head features a washer and a slotted hexagonal shape, allowing easy installation with a flathead screwdriver. It is perfect for use in applications that need frequent adjustments.
Socket Cap Bolt Head
The socket cap bolt head has a cylindrical shape with a flat top and a hexagonal depression in the centre. It is usually used in areas that require high torque, such as the automotive industry.
Button Bolt Head
The button bolt head has a round top that sits flush with the material surface, giving it a sleek finish. This head is perfect for fastening materials used as decorative elements and needs a smooth profile.
Conclusion
Understanding the different types of bolt heads and their uses is essential in ensuring your DIY projects look beautiful and serve their intended purpose. Whether you are working with thin and fragile materials that require a low profile bolt like the oval bolt head or high torque applications like the socket cap bolt head, there is always a bolt head that suits your needs. Knowing which bolt head to use will result in successful and safe DIY projects.
