Choosing the Right

Threading Insert

The production of thread connections is a
common application in the metal working
industry. Most metal working industries
produce parts that are characterized by
external or internal threads, from tiny dental
screws to large thread joints for pipelines
associated with the oil and gas industry.

There are a wide variety of thread types produced in
National and International Thread Type Standards.
Thread types differ in shape and dimension, where
each standard defines a specific thread type. In
many cases, a thread type standard characterizes
a specific requirement for an industrial branch or
main field of application. For example, UNJ and
MJ thread type standards are associated with the
Aerospace industry, and NPT and BSPT standards
are associated with the oil and gas industry for
pipelines, pipe connectors, and fittings.

Thread turning applications are one of the most
productive and common methods for producing
threads in rotary workpieces.
A successful thread type turning application depends
on the selection of the right threading tool. There
are simple steps to selecting an indexable threading
tool correctly; first, identify if the thread is external or
internal for which to choose a right- or left-hand tool.

After choosing the feed direction corresponding to the
thread type, the thread designation will be determined
according to the part drawing and application.
