Thread Measuring Wires with micrometer holders
The three-wire measuring process is one of the most precise procedures for determining the pitch diameter of threads.
The M+T thread measuring wires with micrometer holders combine this procedure with unique handling ease measuring security of the highest order and absolute efficiency.
The corresponding measuring wires position themselves after they have been affixed through the integrated washer springs to the spindle of the measuring screw using the pair of holders.
For classic handling applications we can also supply thread measuring wires with labelled eyelet handles in plastic.
Our thread measuring wires with labelled micrometer holders are available (may depend on version):
- In the diameters of the measuring wire series in accordance with Zeiss or all other diameters from 0.15 mm to 6.50 mm
- In the diameter accuracy
