Abstract
A three-wire apparatus for measuring an external thread features a single length of wire having a first bend and a second bend, which first and second bend divide the single length of wire into first, second and third wire portions. The first, second and third wire portions engage an external thread and are measured using a micrometer or other measuring device. The single length of wire defines an open end for engaging the first, second and third wire portions with the external thread.
Claims10
A wire gauge apparatus for measuring an external thread, the apparatus comprising:
- a. a unitary length of a gauge wire, said unitary length of said gauge wire having a first and a second end, said unitary length of said gauge wire defining a first bend and a second bend;
- b. a first wire portion defined by said unitary length of said gauge wire between said first end and said first bend;
- c. a second wire portion defined by said unitary length of said gauge wire between said first bend and said second bend;
- d. a third wire portion defined by said unitary length of said gauge wire between said second bend and said second end;
- said second and third wire portions being substantially straight and parallel one to another, each of said first, second and third wire portions being configured to selectably engage the external thread, said second and third wire portions engaging the external thread on a first side of the external thread when the apparatus is in engagement with the external thread, said first wire portion engaging the external thread on an opposing side of the external thread when the apparatus is in engagement with the external thread.
