Differences Between Hex Head Bolts and Hexagon Socket Head Bolts

Hex head bolts and hexagon socket head bolts are two commonly used fasteners in a wide range of industries. While both types of bolts have similar functions, they differ in terms of their design and application.

Hex head bolts are also known as hexagonal head bolts, and they have a hexagonal head with a flat top and six sides. The head of the bolt is designed to fit into a wrench or socket for tightening or loosening. Hex head bolts are commonly available in standard and metric sizes, and they are made from a variety of materials, such as carbon steel, stainless steel, and brass.

On the other hand, hexagon socket head bolts have a cylindrical head with a hexagonal socket in the center. The socket is designed to fit a hex key or Allen wrench for tightening or loosening. Hexagon socket head bolts are also commonly available in standard and metric sizes, and they are made from a variety of materials, such as steel, titanium, and aluminum.

In addition, both hex head bolts and hexagon socket head bolts are used in a wide range of applications, such as construction, automotive, aerospace, and manufacturing. However, they have specific applications where one type of bolt may be preferred over the other.

Hex head bolts are commonly used in applications that require higher torque, as the six-sided head provides a larger contact area with the wrench or socket. They are also used in applications where the bolt head may be exposed and require a decorative finish. For instance, hex head bolts may be used in architectural applications, such as railings, gates, and fences, where the bolt head needs to blend in with the design.

Hexagon socket head bolts, on the other hand, are commonly used in applications where space is limited or where the bolt head needs to be recessed. The hexagonal socket in the bolt head allows for a smaller head size, which can be beneficial in applications where clearance is limited. Additionally, hexagon socket head bolts may be used in applications where the bolt head needs to be flush with the surface, such as in automotive and machinery applications.

When choosing between hex head bolts and hexagon socket head bolts, it's important to consider the specific requirements of your application. Some factors to consider include the amount of torque required, the space available for the bolt head, and the desired finish of the bolt head.

In addition to these factors, it's important to choose a bolt that is made from the right material for your application. For instance, if your application requires a bolt that can withstand high temperatures, you may need to choose a bolt made from heat-resistant material, such as titanium or Inconel. Similarly, if your application requires a bolt that is resistant to corrosion, you may need to choose a bolt made from a corrosion-resistant material, such as stainless steel or brass.
