Open end wrenches have two different sized ends on the same wrench and are one of the most common and versatile wrenches. The smaller the wrench end opening， the shorter the body of the wrench， and this is proportionate to the maximum leverage that can be applied to the head of the bolt or nut. By having two different sizes in a single wrench， the number of tools required for a job is reduced.
- Precision broached ends for a perfect fit on nuts and bolts
- Narrow ends for better acces in tight areas
- Oval body for a more comfortable grip
- Steel alloyed with high quality molybdenum vanadium and controlled heat treatment
