This is for Engineers too Machinist who are looking for reference to know nearly Bolt thread damage too standards.
The whole article contains details nearly JIS(Japanese Industrial Standard) Thread specifications, although these specifications are based on JIS notwithstanding they tin equally good utilize to ISO too DIN Thread types.
You volition larn nearly next things:
Exterior Features of Thread ridge - Basic designation(description) of threads explained hither similar definition of flank angle,height of thread,thread overlap,Threaded portion,Length of 24-hour interval of the month etc.
Fig: Bolt specification too Thread damage explanation
Thread types too its applications (Symbol,Profile,Equation to calculate thread designation) - This includes Metric screw thread
| Thread Type | Standards |
| Metric screw thread | JIS B0205(coarse), JIS B0207(fine) |
| Unified screw thread | JIS B0206(coarse),JIS B0208(fine) |
| Parallel piping thread | JIS B0202 |
| Taper piping thread | JIS B0203 |
Thread Tolerance -
mechanical engineers similar professions: 
mechanical engineers similar professions: Fig: Thread tolerance tabular array for external too internal threads
mechanical engineers similar professions: The argue for defining tolerance inwards threads are:
mechanical engineers similar professions: To ensure compatibility
mechanical engineers similar professions: Limit the lineament inside a given range
mechanical engineers similar professions: Factors which consequence lineament of screw thread mainly due to following:
mechanical engineers similar professions: Material - Type,Heat treatment,Surface processing etc
mechanical engineers similar professions: Shape - Root radius,roundness etc.,
mechanical engineers similar professions: Detentions - major diameter,pitch diameter too kid diameter.
mechanical engineers similar professions: Definition of angle fault too pitch fault (pictorial examples)
mechanical engineers similar professions: ISO too JIS standards for Pipe threads-
mechanical engineers similar professions: 
mechanical engineers similar professions: Fig: Pipe thread standards,types too symbols

mechanical engineers similar professions: This is an first-class site to bookmark for yourself, this would help engineers to accept quick reference involve on Bolt types,standards,Tolerance table,Pipe thread standards too and then on.
