Flange Label Clips™ Sizes

Our clips are designed with efficiency and ease of use in mind and feature two clearly visible size markings directly on the surface.

The marking “27” on the right side of the clip indicates the required tool size for maintenance operations. This enables maintenance personnel to instantly select the correct tool, saving time and eliminating the need to measure bolts on site.

On the left side of the clip, the stud bolt size "5/8" is clearly indicated. This removes any guesswork and ensures that the correct stud bolt is used every time.

By providing all critical sizing information at a glance, our clips help reduce maintenance time, prevent errors, and improve overall workflow efficiency.

About Our Sizes

Our sizing range is carefully selected to cover the most commonly used bolts and nuts in industrial applications. Currently, our assortment goes up to 50 mm, which reflects the standard size range used across many industries.

More than 90% of bolts used in daily industrial operations fall between 22 mm and 50 mm, making this the core of our offering. Larger sizes are far less common and are typically reserved for specialized applications, such as high-pressure pipelines or other heavy-duty installations.

By focusing on the most frequently used sizes, we ensure that you’ll find exactly what you need for the majority of tasks. A clear and easy-to-read size chart is provided alongside to help you select the correct size for your specific requirements — from smaller bolts 22mm (1/2"stud bolts) for compact flanges to larger bolts up to 50 mm (1 1/4" stud bolts).

What NUTCLIP sizes to order?

Our NUTCLIP products are made in the most common nut sizes used throughout the industry. We have created a table to clearly show the available sizes.

All sizes are bases on the wrench size of the bolts.

  • All sizes are based on the wrench sizes (in mm) of the nuts. The additional values indicate the corresponding imperial stud bolt sizes (in inches) commonly used for stud bolts. These dimensions are directly related and correspond to one another.

If you need any support for finding the correct NUTCLIP sizes:

  • Visit the site (if possible) and measure the diameter of the nuts. Use the Flange Labelling Clip with the closest matching diameter.
  • Test the bolt sizes using wrenches to determine the correct dimensions.
  • Ask colleagues if they know which bolt sizes are most commonly used in the unit.
  • Contact the company to check whether an (imperial) size table is available for reference.


    If you are still unsure about the required sizes, please contact us. The NUTCLIP team will be happy to assist you.
