ABSTRACT:
An adjustable wrench has a handle and a jaw head extending from one end of the handle. The jaw head is formed of a fixed jaw and a movable jaw. The fixed jaw is composed of a first clamping side, a second clamping side, a third clamping side, and a fourth clamping side. A receiving hole is formed by these four clamping sides and provided with an opening. The movable jaw is axially and linearly displaceable in the receiving hole of the fixed jaw such that the movable jaw is capable of an axial and linear displacement. The movable jaw has a first clamping side and a second clamping. The fixed jaw and the movable jaw form together a jaw mouth having at least three clamping sides to hold securely a hexagonal nut or a bolt having a hexagonal head.
