The 146 non-sparking double open-end offset wrench is die-forged from copper alloy to lend additional strength to its structure. This handy tool consists of two open-ended gripping jaws on both ends connected by a metallic handle that has wide, shallow indented cut into the surface. One primary use of our wrench is in hazardous areas that contain fire or explosion dangers, where it is employed to tighten or loosen hex or square heads of bolts and nuts. The product is surprisingly durable, long-lasting, and stable. It meets the QB/T2613.1 standard.
