Catalog number: WLH130B-7S Features: ●Uses high-quality special chrome vanadium steel (SNCM20V). ●Alloy steel with 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. ●Tightening and removal can be done with continuous rotation, and work time can be reduced several times compared to conventional wrenches. ●Compact short type. ●1.5mm●2.0mm●2.5mm●3.0mm●4.0mm 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: Short
