Quality of Van Keuren Gaging Surfaces
The gaging or working surface of Van Keuren
Thread Measuring Wires is superior to that specified by the most demanding of Federal
standards. For example, the working length of 2" is four times as long and the surface
texture is three times as fine as most standards specify.
In addition, the roundness
of Van Keuren Thread Measuring Wires is assured by 100% inspection in a specially
designed optically-lapped precision vee-block having the same angle as the thread
to be measured. All Van Keuren measuring wires meet former Federal Specifications
GGG-W-366b, which for identity of size, taper and roundness requires a tolerance
of .00001" for Grade A Wires.
