These are various ISO standards related to fasteners, bolts, screws, and other types of mechanical components. Here's a brief description of each standard:

  1. ISO 10511: This standard specifies the requirements for hexagon nuts with metric coarse and fine pitch thread.

  2. ISO 10512: This standard specifies the requirements for taps for internal threads with metric dimensions.

  3. ISO 7040: This standard specifies the requirements for prevailing torque type hexagon nuts (with non-metallic insert).

  4. ISO 10513: This standard specifies the requirements for taps for internal threads with inch dimensions.

  5. ISO 7042: This standard specifies the requirements for hexagon head screws with metric dimensions and thread pitch.

  6. ISO 21670: This standard specifies the requirements for metric series bolts with reduced shank and pilot bore.

  7. ISO 4034: This standard specifies the requirements for hexagon nuts, style 1, with metric dimensions and property classes.

  9. ISO 8673: This standard specifies the requirements for hexagon head screws with metric coarse pitch thread.

  10. ISO 4032: This standard specifies the requirements for hexagon nuts, style 2, with metric dimensions and property classes.

  11. ISO 7047: This standard specifies the requirements for countersunk flat head screws with cross recess.

  12. ISO 7046: This standard specifies the requirements for countersunk flat head screws with hexagon socket.

  13. ISO 2010: This standard specifies the requirements for hexagon nuts with metric fine pitch thread and mechanical properties.

  14. ISO 2009: This standard specifies the requirements for hexagon bolts with metric fine pitch thread.

  15. ISO 8676: This standard specifies the requirements for hexagon head screws with inch dimensions.

  16. ISO 8765: This standard specifies the requirements for hexagon nuts, style 1, with inch dimensions and property classes.

  21. ISO 8738: This standard specifies the dimensions for grooved pins.

  22. ISO 2340: This standard specifies the dimensions of straight pins.

  23. ISO 2341: This standard specifies the dimensions of cylindrical pins with internal thread.

  24. ISO 8739: This standard specifies the dimensions for parallel pins.

  25. ISO 8744: This standard specifies the dimensions for split pins.

  26. ISO 8745: This standard specifies the dimensions for grooved pins with round head.

  27. ISO 8740: This standard specifies the dimensions for parallel pins with internal thread.

  28. ISO 8741: This standard specifies the dimensions for parallel pins with internal thread and full length taper.

  29. ISO 8742: This standard specifies the dimensions for grooved pins with internal thread.

  30. ISO 8746: This standard specifies the dimensions for grooved pins with round head and centre hole.

  31. ISO 8747: This standard specifies the dimensions for grooved pins with internal thread and full length taper.

  32. ISO 8752: This standard specifies the dimensions for spring-type straight pins.

These standards are useful for manufacturers and designers to ensure that their products meet industry standards and are compatible with other components
