Frequently Asked Questions:
Q. How does an open-end wrench work?
A. The open end permits the tool to be slid over the nut in tight quarters where the length of a pipe or shaft interferes with operation, or where there is insufficient space for a socket / box wrench.
Q. Why are wrenches preferred over spanners?
A. Wrenches are preferred over spanners because they have a long arm. This allows less force to be required for generating a turning effect to unscrew a nut.
