Catalog number: WLB130B-9S 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 diagonally into screws in narrow spaces or hidden places without damaging the threads. ●It can be tightened and removed by continuous rotation, and the working time can be reduced several times compared to conventional wrenches. ●It is a compact short type. ●1.5mm●2.0mm●2.5mm Specifications: ●Set contents (mm): 1.5/2.0/2.5/3.0/4.0/5.0/6.0/8.0/10.0 ●Set contents (pieces): 9 ●Surface treatment: Parker finish ●Tip ball shape ●Size: Short Material/Finish: ●Chrome vanadium steel
