151 Non-Sparking Double Box-End Offset Wrench

The 151 non sparking double box-end offset wrench is made of copper alloy that has been subjected to drop forging process. It has high tensile strength, and is long-lasting while providing stable mechanical performance.

This series of wrench is specially intended for use in tight spaces or deep concaves where straight wrench fails to fit in. It produces less sparks from intense friction with the workpiece than is possible with an ordinary steel wrench. Thus this tool can be used in various potentially flammable or explosive areas to fasten or loosen the hex heads of nuts or bolts.
