How to Use a Box End Wrench

Bolts should be secured properly to ensure that they can perform their task. A box-end wrench is a wrench used to secure non-square bolts which completely encapsulates the nut effectively "boxing" it in. It is also known as a "socket wrench" or a "ring spanner." You can use a box-end wrench to manipulate a nut where space is limited. You just need to use the correct size wrench for the nut.
