ABSTRACT:
Provided is a self-adjustable universal spanner employing a variable jaw sizing feature including: a spanner head having an upper slide groove and a lower groove for inserting a bolt therebetween; a ratcheting size-adjustment member slidable along the upper groove to fasten and unfasten the bolt; and a jaw sizing member movable in the lower groove in a stepped manner to vary a width between the ratcheting size-adjustment member and the jaw sizing member so that the spanner can fasten and unfasten various sizes of bolts. In addition, a pair of bolt holding members may be installed between the upper and lower grooves. Therefore, the present invention is capable of fastening or unfastening more sizes of bolts than that of a single spanner head. In addition, it is possible to fasten bolts and nuts using a user's one hand by employing a bolt holding member.
