There's a variety of different reasons you may have needed to reference the chart, so we hope it was useful for you! Here at Echo, we use it to help powder coaters, e-coaters, anodizers, and platers find the correct sized cap or plug for their specific thread size.  So, here are a few tips in case you ever need it.

If you're in need of a masking solution or simply have a question you'd like to ask us, please fill out the form below and we will get back to you as soon as possible!

Titan USA End Mills with 2 flutes, optimized for high speed slotting and profiling in aluminum and non-ferrous materials.

For tapered plugs, you'll want to closely match the minor diameter to the middle diameter of the plug (see graphic).  If it's not exact, seat the plug deeper in the hole. When you install these plugs, you push them in and then turn them to get a better seal.

Offered in a variety of length styles and end profiles, and ZrN coated for increased speed rates and prolonged tool life, this Titan USA solid carbide end mill selection is specially designed for high speed slotting and profiling in aluminum and non-ferrous materials.

Echo Engineering has been providing masking solutions to industrial finishers for well over 50 years.  Because of that, we are frequently working closely with paint lines to help them find ways of masking off threaded holes and bolts.  We specialize in not only standard catalog options, like powder coating tapes, caps, and plugs, but also in designing, engineering, and manufacturing custom solutions for some of the largest metal finishing lines in the world.

Thread fit is a measure of looseness or tightness of mating thread.  It is specified to designate the amount of tolerance allowance and installation fit desired. There are three different classes of thread fit that they come in:

The simple version of finding the right size cap is that we suggest finding one that has an ID (inside diameter) that is 1-2 sizes smaller than the Major Diameter of the thread you're masking off.  You want to get a tighter fit for processes like e-coat.

UNF threads are fine threads, so this will require more turns to tighten the plug into the hole.  UNC threads are coarse threads, so they require fewer turns to tighten the seal.

You'll find a quick reference chart for UNC/UNF - Unified National Threads in this post.  If you're new to any of the terminology, scroll down past the chart, and you'll find a list of definitions to help you better.  The chart below will focus on the major diameters for external threads and the minor diameters for internal threads.  We've included the image below to show these areas better.
