Pitch Diameter Measurement of Thread Plug Gauge

Background of the Application

The mechanical threads of bicycle fasteners are mostly fine threads. Traditionally, thread plug gauges are popularly used for inspection, the contact gauges will wear out, and only the GO/NOGO results.
Currently, the method of pitch diameter measurement is mainly based on the three-wire gauge. However, problems such as gauge wear and reproducibility of personnel operations have increased the uncertainty of measurement.

Solution

Implementing TIMI 34P precision measuring instrument to simulate the measurement method of a three-wire gauge and calculate the pitch diameter of the mechanical thread.

Features

The error range for measuring the pitch diameter of the thread plug gauge is within ±3µm compared with those of the standard thread plug gauge.
Measure the outer diameter, inner diameter, pitch diameter, pitch, and thread angle of the thread plug gauge within one second.

Benefits

Thanks to instant “Select-Measure” technology, the physical dimensions of bicycle fasteners’ thread can be measured within one second. The measured results can be traced back to the standard thread plug gauge. It is very suitable for monitoring the sizes of thread plug gauges in mass use.
