What statement is true concerning the use of wrenches and drive tools as used to manipulate threaded fasteners?

AWhen extra leverage is needed for wrenches and drive tools, the use of a cheater bar is recommended.
BPush wrenches and drive tool handles rather than pull them for greater control and balance and to avoid injury.
CSix point sockets are less prone to slippage than twelve point sockets.
DFor initial breaking loose and final tightening of fasteners, the use of open end wrenches is recommended.
AI Explanation

The correct answer is C) Six point sockets are less prone to slippage than twelve point sockets. The reason this is the correct answer is that six point sockets provide a tighter fit on the fastener, reducing the risk of the socket slipping and potentially damaging the fastener or causing injury. Twelve point sockets, on the other hand, have a looser fit and are more prone to slippage, especially when significant torque is applied. The other answer choices are incorrect because: A) Using a cheater bar to provide extra leverage can be dangerous and should be avoided; B) Pushing wrenches and drive tools is generally safer than pulling them; and D) Open-end wrenches are not recommended for initial breaking loose or final tightening of fasteners, as they provide less control and stability compared to sockets.
