which of the following is true about torque - to - yield fasteners? a) they are larger in diameter than conventional fasteners. b) once stretched, they must not be reused. c) they cannot be deformed. d) they are made of aluminum.
Answer
Brief Explanations:
Torque - to - yield fasteners are designed to be stretched to their yield point during installation. Once stretched to this point, their mechanical properties change and they must not be reused as they may not provide the required clamping force or could fail under load. They are not necessarily larger in diameter than conventional fasteners, they are deformed during installation (to the yield point), and they are not always made of aluminum.
Answer:
B) Once stretched, they must not be reused.
