Catalog number: WLH230B-7S Features: ●Uses high-quality special chrome vanadium steel (SNCM20V). ●An alloy steel that combines hardness and wear resistance. ●In order to ensure uniform and highest precision tempering (unique heat treatment) hardness (HRC60°±1°), a completely non-oxidizing, decarburization correction quenching method using a closed furnace is used instead of a continuous furnace. ●Tightening and removal can be done with continuous rotation, reducing work time several times compared to conventional wrenches. ●1.5mm●2.0mm●2.5mm●3.0mm●4.0mm●5.0mm Specifications: ●Set contents (mm): 1.5/2.0/2.5/3.0/4.0/5.0/6.0 ●Set contents (pieces): 7 ●Surface treatment: Parkerized ●Size: Semi-long
