Catalog number: WLB230B-7S Features: ●High-quality special chrome vanadium steel (SNCM20V) is used. ●It is an alloy steel that combines hardness and wear resistance. ●In order to ensure uniform and highest precision tempering (unique heat treatment) hardness (HRC60°±1°), we have adopted a completely non-oxidizing and decarburization correction quenching method using a closed furnace instead of a continuous furnace. ●The tip is machined into a ball shape, so it fits quickly into the screw hole. ●It can be inserted at an angle into screws in narrow or hidden places without damaging the thread. ●It can be tightened and removed by continuous rotation, and the working time can be shortened several times compared to conventional wrenches. ●1.5mm●2.0mm●2.5mm●3.0mm Specifications: ●Set contents (mm): 1.5/2.0/2.5/3.0/4.0/5.0/6.0 ●Set contents (pieces): 7 ●Surface treatment: Parker finish ●Tip ball shape ●Size: Semi-long Material/Finish: ●Chrome vanadium steel
