Brief Explanations:

  • For question 7: Helicoil inserts are small, stainless - steel spring - like devices. They have internal and external threads, but the most common description is their spring - like appearance.
  • For question 8: Spraying a broken bolt with penetrating oil is a standard first step to loosen it before using a bolt extractor.
  • For question 9: Pins are non - threaded fasteners often used to secure shafts and linkages.
  • For question 10: Dies are used to cut threads on a non - threaded rod.

Answer:

  1. B. They look like small, stainless - steel springs.
  2. D. Spraying the bolt with penetrating oil.
