Double open end spanners, also known as double ended wrenches, are wrenches with two heads of different sizes on either end. Unlike their chrome vanadium steel (CR-V) counterparts, these are made from carbon steel.
Carbon steel is a less expensive option than CR-V steel, but it is also not as strong or corrosion-resistant. This means that carbon steel spanners are more likely to bend or break if they are used on high-torque applications, and they may also rust over time.
Here are some of the benefits of using double open end spanners made from carbon steel:
Here are some things to consider when choosing double open end spanners made from carbon steel:
