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.

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.

May 17, 2007 — Normal tolerance on milling cutter insert height is +/-.002 or +/-.003 depending on the manufacture (radial runout is more important than axial for tool life).

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.

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.

Regardless of component size, material or design, the carbide insert grade you use can make all the difference in your manufacturing productivity.

Cutting speed is defined as the speed at the outside edge of the tool as it is cutting. This is also known as surface speed.

There are various thread types and sizes to choose from these days.  Occasionally, you need to know the dimensions associated with those threads, so we're developing posts like this one to make it easy for you.

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.
