Ko-ken Products are designed and manufactured using the latest technologies such as 3D-CAD, machining centres and computer controlled heat treatment systems in order to deliver the highest quality and most modern designed sockets and accessories.
Koken S.O.D.H. System is the two dogs (pawls) are located in the ratchet body so that the dogs (pawls) and springs are held securely in place, allowing the reversing lever and dog (pawl) to switch smoothly. The torque load on the gear is transmitted vertically to the dog (pawl) and in turn, down the ratchet handle. This mechanism locks gears tightly in place while torque is being applied, thus avoiding any gear slippage.
Two-Step Dog (Pawl): Two flats hold two teeth of the ratchet gear, increasing the maximum torque load of the ratchet compared with a single step system.
Flex handles are socket wrenches in which the drive head pivots back and forth on the handle, to allow the handle to avoid obstructions when being turned in a cramped space.
