Many sheath-screw davits have markings to indicate the maximum angle to which they should be cranked out. If the angle is exceeded, the davit __________.

Correct Answer: Option A — screw may come out of the sheath

Sheath-screw davits operate via an internal threaded shaft. Exceeding the maximum designated cranking angle causes the operating screw to extend past its threaded engagement point, potentially stripping or coming completely out of the sheath, causing mechanical failure.
