Civil Engineering QUESTION #6617
Question 1
Which type of bolt is intended to be tightened to a high tension so that the load is transferred by friction between the connected parts?
  • A307 (Common bolts)
  • Slip-critical high-strength bolts✔️
  • Bearing-type high-strength bolts
  • Anchor bolts
Correct Answer Explanation
Slip-critical connections rely on the friction (frictional resistance) developed between the faying surfaces due to the clamping force of pre-tensioned high-strength bolts.
