Pin & Stud Insertion

Pin and Stud Insertion with Factory Presses

Pin and stud insertion is a process used to fasten or align objects in assembly, create a pivot, or keep objects steady for further applications, and is an application used across many different products and industries. With a wide variety of pins, studs, and dowels, it’s possible to find a pin, dowel or stud suitable for a large range of purposes. Fastening with different pins and studs, for instance, can create a secure, permanent fit, a removable fit, or a fit that allows the right amount of movement between two objects depending on the type of pin and the design of the separate pieces. Regardless of the materials or what type of pins, studs, or dowels you’re working with, an industrial press can help to deliver consistent pressure, accuracy and even automate your pin insertion process.

Pins vs. Studs

Pin and studs are commonly used across a broad range of assemblies. Pins are primarily used for precision location between two components whereas studs are typically threaded; meaning they are used to fasten one object to another, like a wheel hub assembly onto a drive axle.

Types of Pin and Studs

The many different types of dowels, pins, and studs allow manufacturers to align or fasten many different metals and components together. Pins and studs with different types of grooves, shapes, and threads, as well as different sizes and materials, can affix materials together in a variety of ways. These are just a few examples of the dowels, pins and studs that our presses work with.

Solid or Hollow Pins

Pins for fastening objects together may be either solid or hollow. Hollow pins and dowels might be used for positioning, assembling, or fixing parts together. These types of pins are lighter, and might be used to reduce the weight of the assembled piece. Additional processes may reinforce the join. Solid pins, studs or dowels are generally sturdier and may be used in more demanding applications. These solid or hollow pins might use grooves or threads to create an easier or stronger connection.

Spring Pins

Spring pins are typically installed in a hole that is smaller in diameter than the pin itself. The pin decreases in diameter as it’s installed which allows for a tight fit. Once installed the pin exerts a retaining force against the walls of the hole which helps keep it securely in place.

Symmetric or Asymmetric Studs

Symmetric studs have the same threading on both sides, with an unthreaded middle section. These might be smooth, or they might be grooved, knurled, or barbed, according to the assembly requirements. These changes in design can create a stronger connection or allow for movement, as needed. Asymmetric pins or studs are more similar to screws, since they use a wider shape and may be knurled at one end. This can make it easier to fix the materials or components together.

Press-Fit Studs

Press-fit studs are designed with threads or knurling that create a permanent bond when pressed into pre-punched or pre-drilled holes in sheet metal.


Self-clinching studs are generally used to fix thinner pieces of metal together. The threads on the sides of self-clinching studs are similar to screws, and create very tight, reliable connections. Applying self-clinching studs to different materials with a factory press makes it possible to securely, permanently fasten materials together, even those exposed to harsh conditions.


Knurled Pins are heavily serrated around a portion of the diameter and similarly extrude radial force when compressed into a hole for a secure, permanent fit.

Precise, Durable Pin and Stud Insertion

Pin and stud insertion requires the right amount of force as well as a great deal of precision. If the press exerts too much force on the pin, stud, dowel, or the fastening objects, it can cause cracks, chips, warping, or other damage. For many manufacturing, assembly, and similar applications, it’s also important to insert pins and studs quickly. Finally, if the pins and studs aren’t inserted in the right place, the pieces won’t be fastened properly. Finding the right press to accurately, efficiently, and safely complete pin and stud insertion tasks allows you to streamline your manufacturing process.
