Calipers are similar to micrometers in shape but instead of measuring distances, calipers are used to transfer distances between objects.

You need to loosen a bolt in a hard to reach location. Which of the following wrenches would best suit this task?
spanner |
|
open-end |
|
adjustable |
|
box-end |
Wrenches are used to provide grip and mechanical advantage by applying torque to turn objects (or to keep them from turning). The longer the wrench, the more torque that can be applied. Wrench ends are available in two primary types, open-end and box-end. A box-end wrench encloses the bolt head and is useful when more torque is needed or to maintain contact in difficult to reach locations. An open-end wrench is designed for speedily loosening easier to reach fasteners. Wrenches that feature one open and one box end are called combination wrenches and adjustable wrenches feature an open end with an adjustable width.
