Stud Bolts and their different types

Fasteners are important for the assembly of parts, allowing them to be temporarily or permanently joined together. Depending on the application and one’s particular needs, there are a number of fastener types, each with its own unique designs and capabilities. Stud bolts, or threaded rods, are a common component that comes in the form of a rod with external threading on each end, and they are often used in tension. In this blog, we will discuss stud bolts in detail, allowing you to better understand their types, capabilities, and applications.

As stated before, a stud bolt will typically have threading on both ends of the rod, and this threading may extend across the complete length of the component. Unlike similar fastener types such as a conventional bolt, studs do not feature a head that sits against the surface of installation components. For their installation, studs are often paired with mating hexagon nuts that are installed on each side of the fastener to secure it in place. Generally, hexagon-shaped nuts are the most common choice due to their optimal torque characteristics.

Depending on the particular design of a stud bolt, threading patterns may vary. To help you find the best fit for your particular requirements, we will briefly discuss some of the most common stud bolt designs that are available for purchase.

Continuous Threaded Stud Bolt: Continuous threaded stud bolts are those that feature full threading across the length of the rod while being devoid of chamfered ends. As the most basic option, such stud bolts have uniform threading to support standard assemblies.

Flange Stud Bolts: Flange stud bolts are fully threaded across the length of the rod, and they set themselves apart from continuous threaded variations with their chamfered ends. Due to the differences of such components, it is important to know that flange stud bolt lengths are measured from the first to last threading, rather than from each chamfered end.

Double End Stud Bolts: Double end stud bolts are fairly similar to the continuous threaded stud bolt, albeit having a central portion of the rod that is free of any threading. Generally, these components are useful for creating a hidden joint within an installation.

Tap End Stud Bolts: Tap end stud bolts have threading on each end of the bolt and a smooth portion in the middle, though their threading is unequal on each end of the fastener. This is due to the fact that one end of the stud bolt is designed to be the nut end, while the other is the tap end.

Double End Stud Bolts With a Reduced Shank: These variations of stud bolts are fairly unique, featuring equal thread lengths where the center is reduced further than the diameter of the stud itself. Generally, such stud bolts find use within the wind energy sector due to their design and tolerance characteristics.

Welding Studs: Welding studs are the final major type of stud bolt that one may take advantage of, and they are threaded on one side of the component. Generally, the threaded side of the fastener will be used alongside a nut for securing an assembly, while the unthreaded side is welded to a support. During the manufacturing process, welding studs are most commonly produced as per DIN 525.

With the various characteristics of each fastener, one can establish assemblies with reliable integrity and security. As fasteners will face various stressors over the course of their service lives, it is important that they are regularly inspected, maintained, and replaced as necessary.
