Our manufacturing partner in Jinhua, Zhejiang has produced hand tools for three decades and supplies branded programs across North America, Europe and Southeast Asia. We manage the program; they run the steel.
Cold-forged CR-V, S2 and carbon steel blanks with controlled grain flow for torque strength.
Component-specific hardness: HRC 48–52 for sockets and ratchets, HRC 58–60 for precision bits.
CNC profiling, thread rolling and mirror-chrome plating with salt-spray corrosion screening.
Kit assembly, laser marking, label application and retail carton packing under one roof.
