WLB230B
Ball Point Hex Wrench (Semi-Long, Black) WLB230B
High quality special chrome vanadium steel (SNCM20V) is used.
This alloy steel combines hardness and wear resistance.
Set of 7: 1.5mm,2.0mm,2.5mm,3.0mm,4.0mm,5.0mm,6.0mm
Set of 9: 1.5mm,2.0mm,2.5mm,3.0mm,4.0mm,5.0mm,6.0mm,8.0mm,10.0mm
To ensure homogeneous and highest precision tempering (proprietary heat treatment) hardness (HRC60°±1°), we dare not use a continuous furnace, but use a completely non-oxidizing and decarburizing compensated hardening method in a closed furnace.
The wrench can be tightened and dismounted by continuous rotation, which reduces working time several times faster than conventional wrenches.
