Abstract: An adjustable wrench as in FIG. 1 whereas the wrench 3 become a chain wrench and has a hole through the handle 5 for a chain shackle 4 and the Movable jaw member 2 has a pointed tooth 6 and radiused surfaces 7 on the inclined location. The jaw 2 tongue 8 has a recess 9 for a clock spring 10 its ends being fixed by holes 16 to both the movable jaw tongue 8 and the Handle 3 this spring 10 is preloaded so that the movable Jaw 2 forces towards the gripping surface on handle 3, the coiled portion of the spring being accommodated in the jaw tongue recess 9. The upper comer of movable Jaw 2 incorporates a pistol hammer shaped thumb grip 11. The handle edge 12 being a straight edge ruler with metric and imperial measurements 13 imbedded into the sides of the handle. On the handle ends, there is a radiused hexagonal shaped ring spanner 14 which is for imperial and metric bolts.
