Question 216General Subjects - QMED

The correct answer is B) Box end wrench. The box end wrench is superior to the other options in practically eliminating the possibility of slipping off while tightening a nut or bolt. This is because the box end wrench has a fully enclosed head that grips the nut or bolt on all six sides, providing a secure and positive fit. This design minimizes the risk of the wrench slipping off compared to open-end wrenches, crescent wrenches, or monkey wrenches, which have a more limited contact area with the fastener. The other options, such as the open-end wrench, crescent wrench, and monkey wrench, are more prone to slipping off the nut or bolt due to their more open-ended or adjustable design, which can allow the wrench to slip and potentially damage the fastener or the surrounding area.
