Question

1. technician a says most us bolts have a thread pitch between 1.0 and 2.0 threads per millimeter. technician b says 1.0 thread pitch is a finer thread than a 2.0 thread pitch. who is correct? a. technician a b. technician b c. both a and b d. neither a nor b

Explanation:

• US bolts use threads per inch, not threads per millimeter. So Technician A is incorrect.
• A lower thread pitch (fewer threads per unit length) means a coarser thread. So 1.0 thread pitch (if we assume the unit was mis - stated) is coarser than 2.0 thread pitch. So Technician B is incorrect.

Answer:

d. Neither A nor B
