DEWALT Ratchet Wrenches
Ratchet wrenches are wrenches with a ratchet mechanism incorporated in the wrench part of a box end wrench. The ratchet mechanism enables efficient work as it can be turned continuously secured to the bolt or nut once the head is inserted. There are also box end wrench type air ratchet wrenches, which can apply force to 6 points instead of the 2 points wrenches ordinarily do to securely tighten the bolt. A ratchet wrench that fits the size of bolt or nut used must be used. Rod-shaped wrenches where the grip is a "spike" is used for various work such as winding tie wire and passing through the holes in steel frames. There are also easy-to-use wrenches such as those with a wrench on the opposite side and those with wrenches of different sizes on each end.
