What Are Standoffs?

Categories: Modular Fixturing

Even the smallest part can have a huge impact on quality. That’s definitely the case with standoffs, which are separators used to keep different parts unconnected from one another. Standoffs are available in a wide range of materials, such as nylon, brass, aluminum, and more.

They also have numerous applications. They’re often used in computer assembly to ensure proper airflow between components, which is key to keep systems from overheating while in use. 

For more than 43 years, Rayco Fixture has provided quality products to numerous businesses throughout many diverse industries. We’re dedicated to creating quality fixtures that you can trust, regardless of the application.

We can handle high-volume orders with care and efficiency, which ensures your satisfaction. We also offer custom-design of fixtures to ensure they meet and exceed your expectations. 

Understanding Coordinate Measuring Machines (CMM) 

CMMs are used to determine whether a part or component conforms with relevant specifications. These devices precisely measure an object using a probe. Probes can be optical, laser, or mechanical and move along an X, Y, and Z access.

CMMs can be computer or operator-controlled. Standoffs and other fixtures can be used to hold objects in place while being measures in a CMM. Fixtures can be dedicated, meaning permanently affixed in place, or modular, meaning they can be changed based on the application. 

The Difference Between Standoffs and Spacers

Both standoffs and spacers can be used to keep components separate when necessary. However, there is one important difference between these two fixtures. Standoffs are often threaded, which allows them to be screwed in place.

Spacers are not usually threaded, although they can be in some instances. Spacers do allow for a bolt to be inserted. This bolt helps keep the assembly together and stable once everything is attached. 

Types of Standoffs

In addition to standard versions of fixtures, standoffs can also be created with customizable threads for specific applications. This includes the number of threads, as well as the size of threads in the standoff.

Magnetic standoffs feature easy locking for more efficient assembly. Instead of screwing or twisting, the pieces lock together through magnetism. There are also many other types of standoffs available, including:

  • Pin
  • Rotating
  • Rounded
  • Spring Loaded
  • Tapered
  • Tooling Ball

How to Choose the Best Standoff for Your Needs

As illustrated above, standoffs come with a wide variety of attributes to meet varying needs. Finding the best type for your application requires a few considerations, such as the application, the industry your business occupies, and other considerations.

Standoffs are also available in a variety of shapes. This includes round, hexagonal, and square varieties. While the average diameter of standoffs is ¼ of an inch, other sizes are also available. There are also different lengths, which range from ¼ of an inch to 2 inches. 

Determining thread type is also crucial. Female-female types have full or partial threading on each end, while male-female types feature internal female threads on one end and external male threads on the other.

There are also male-male types, on which both ends have external threads. Additionally, these external threads can vary in size.
