Metric Screw Thread Profile
- Thread form angle : 60°
- P : Pitch
- H : Height of fundamental triangle
- h : Height of thread
- D : Major diameter of internal thread
- D1 : Minor diameter of internal thread
- D2 : Pitch diameter of internal thread
- d : Major diameter of external thread
- d1 : Minor diameter of external thread
- d2 : Pitch diameter of external thread
- LE : Length of Thread Engagement
Metric Screw Thread Tolerance
- T : Tolerance
- TD1, TD2 : Tolerance for D1, D2
- Td1, Td2 : Tolerance for d1, d2
- ES : Upper deviation of internal thread
- es : Upper deviation of external thread
- EI : Lower deviation of internal thread
- ei : Lower deviation of external thread
- G, H : tolerance positions for lower deviation of internal thread
- e, f, g, h : tolerance positions for upper deviation of external thread
(a) Example of internal thread M Profile : M6 x 1 – 5H6H
- M : Metric thread symbol
- 6 : Size
- 1 : Pitch
- 5H6H : Tolerance class
- 5H : Pitch diameter tolerance symbol. “5” : tolerance grade and “H” : tolerance position
- 6H : Minor diameter tolerance symbol. “6” : tolerance grade and “H” : tolerance position
If the tolerance class for Pitch diameter and Minor diameter are identical, it is not necessary to repeat the symbols. For example : M6 x 1 – 6H6H should become M6 x 1 – 6H
(b) Example of external thread M Profile : M6 x 1 – 4g6g
- M : Metric thread symbol
- 6 : Size
- 1 : Pitch
- 4g6g : Tolerance class
- 4g : Pitch diameter tolerance symbol. “4” : tolerance grade and “g” : tolerance position
- 6g : Major diameter tolerance symbol. “6” : tolerance grade and “g” : tolerance position
If the tolerance class for Pitch diameter and Major diameter are identical, it is not necessary to repeat the symbols. For example : M6 x 1 – 6g6g should become M6 x 1 – 6g
