9Pcs Double Open End Wrench(Metric)

A 9-piece double open end wrench set refers to a set of wrenches that includes nine different sizes, all designed for use with metric fasteners. Double open end wrenches, also known as open-end wrenches or spanners, have a U-shaped opening at both ends.

While the specific sizes may vary depending on the set, a typical 9-piece metric double open end wrench set could include the following sizes:

6mm
7mm
8mm
10mm
12mm
13mm
14mm
17mm
19mm
These sizes cover a range of commonly used metric fasteners, allowing you to work with various nuts and bolts in different applications.

Double open end wrenches are simple and versatile tools commonly used in automotive repair, mechanical work, and other applications where metric-sized fasteners are encountered. They offer the advantage of a slim profile and the ability to quickly flip between the two ends without the need to reposition the wrench.

When using double open end wrenches, it’s important to choose the correct size that matches the fastener to avoid damaging the fastener or the wrench itself. Ensure that the wrench is fully engaged on the fastener and apply force gradually to prevent slipping or rounding of the fastener.
