Wrenches and Hex Keys
In 2004, our company developed the first batch of high end wrenches in China and put it in production. In terms of materials, our wrenches and hex keys fall into two categories, which are high end type and middle end type. High end type is made of superior quality Cr-V steel, while middle end utilizes carbon steel. The wrench surface can be black nickel plated, chrome-plated or black coated.
Adjustable wrenches' jaws are designed with enlarged opening range. Features of laser calibration and cold rolled worm, the torque of our wrench is complied with American standards. The hex keys are processed by thermal treatment. In order to meet the different demands, we add additional part in the rear of the wrench, so it can be used as box spanner or crowbar.
