Tips: What is an box end wrench?

A box end wrench or spanner is a spanner with enclosed ends with 6, 8, 12, or 16 points inside the head. With 45 degree or other degree offset, this wrench box end is staggered from the handle at the side view. Therefore, the box end spanner is often used to remove bolts and nuts assembled in the recessed space, and can be used to provide operational clearance for the fingers to prevent scratches.

The inner hole of the box end spanner is formed by two regular hexagon concentric stagger 30°. Most box end wrenches are offset, which are usually between 10° and 45°. There are many different sizes of box end wrenches. The size of box end spanner is generally determined by the width of the opposite side of hexagon nut or the screw. The general specifications of the spanner in Metric are 8*10mm, 10*12mm, 12*14mm, 14*17mm, 16*18mm, 17*19mm, 19*22mm, 22*24mm, 24*27mm, 27*30 mm and so on. The wrench should be selected that corresponds to the size of the bolt or nut.
