SUPER, DOUBLE-SIZE Reversible Claw Type RN 17 X 21 MM.The surper tool ratchet wrech was invented and designed in 1962.They were first mass-produced by drop forging of special alloyed steel.Since then it has been manufactured by several companies in japan,and has become characteristic Japanese tool.The ratchet wrench is different from the sochet wrench in that the socket has already been fixed to the handle as one body.The ratchet wrench can be turned clockwise or counter-clockwise.The end of the handle is designed to be spear-like. The ratchet wrenches are used for tightening and loosening nuts and bolts and the spear is used to align the position of the bolts holes at work sites such as those on the steel structures, towers and bridge beams. As there is no danger of the socket falling off,the ratchet wrench works well especially in the civil engineering and construction industries where worders are assembling scaffold at heights.
