The 157 non sparking single bent end box wrench adopts the Japanese design that provides great flexibility and aesthetic appeal. One major purpose of the box wrench is to cope with atmospheres that might incur fire or explosion. To achieve this purpose, the wrench is drop-forged from copper alloy. It is also able to get in and turn around in tight spaces where movement is limited and using straight wrench is impractical.
The wrench has a metal bar bent at one end near the socket to such a large angle that the bar will no longer interfere with adjacent bolts during its rotation. Since the drop-forging process lends extra strength to the structure, the wrench is able to withstand a long time of use and deliver stable mechanical performance at the same time. The product is manufactured in strict accordance with Japanese Industrial Standard. Therefore customers can purchase with confidence without worrying about any quality issues.
