U.S. & Metric Thread Measuring Wire Sets, #EG06-1002
- 48 pieces 16 different sizes for all 60° threads.
- Measures all threads from 3 to 48 threads per inch and all metric from 0.5mm to 6mm pitch.
- 3 wire method of measuring external threads.
- Wires are fitted in a plastic case stamped with sizes.
- Laminated chart complied from the U.S. Standard
- Handbook H.28. gives proper sizes & measurements over wires.
-
Comes with 4 wire holders
-
Each holder has 2 pair of holes
-
Each pair of holes for different size of wire
-
Make pitch diameter measuring much easier
3-wire-method of checking pitch diameter of screw threads
- M: measurement over wires
- E: pitch diameter of thread
- D: basic major or outside diameter
- W: wire diameter
- P: thread pitch
- M = E +Const
- E = M - Const
- Const.= 3W-86603p (found in chart)
* The maximum and minimum pitch diameter(E) for each class of thread can be found in machinery handbook
