151 Non Sparking Double Box End Offset Wrench
The 151 Non Sparking Double Box End Offset Wrench works the same way as the 141 model. It is die-forged from copper alloy that not only gives additional strength to the structure but also helps with the ability to withstand a long time of use while delivering outstanding mechanical performance. Its spark-proof feature makes the wrench suitable for use in areas where potential flammable or explosive hazard might occur.
Usually used with a hammer, the wrench can provide large amount of torque to the large-sized hex heads of fasteners for loosening and tightening. It is able to fit in tight spaces. The griping face of the jaw is displaced to a 45 degree angle relative to the line of handle. This displacement allows the wrench to obtain larger areas for rotation. Additionally, the product conforms to the Q/ZBF-141B standard.
