Rayco’s fixture plates help aerospace manufacturers achieve repeatable, efficient, traceable results that exceed the most exacting tolerance specifications, allowing large parts to be measured on any size CMM.

Factors to Consider When Selecting a Fixture Plate

There are several key factors to consider when choosing a tooling plate, chief among them being the desired application. 

Does your application heavily rely on dimensional control? Are precision and dimensional stability important? 

Next, you must also consider how the plate will be mounted (horizontally, vertically, etc.). 

Lastly, you also need to think about the fasteners you are using (their nominal diameter and their threads per inch or millimeter). We can customize our fixtures based on inch and metric thread sizes; as previously mentioned, we offer ¼-20-inch thread types, as well as M4, M6, and M8 metric thread types.

Steel Versus Aluminum Fixture Plates

Rayco sells both aluminum and steel fixture plates. You may be wondering which material is best for your needs. Take a look at our list of pros and cons below:


  • Durable: Steel is typically more durable than aluminum. You will notice less damage or threading wear with steel.
  • Weight: Heavier than aluminum, which helps keep a fixed position. 
  • More Expensive: Due to its durability and strength, steel tends to have higher upfront costs.


  • Cost-Effective: Manufacturers looking to spend less money will want to choose aluminum. 
  • Lighter: Aluminum is a lightweight material and easier to move around.
  • Corrosion Resistance: Aluminum is usually more prone to corrosion when compared to steel. However, Rayco offers hard-anodized aluminum fixtures. Hard-anodized means that our aluminum goes through an electrolytic process. In this process, an electrical current causes oxide, which then hardens on the aluminum and makes it more resistant to corrosion. This type of aluminum is very corrosion-resistant and great for electronic equipment manufacturing applications.

As we mentioned earlier, knowing what type of application you need a fixture plate for is the first step in choosing the right type. Both materials have their advantages and disadvantages. Please contact Rayco today with any questions, and we’ll get back to you as soon as possible.
