1. A torque wrench for engaging a workpiece, comprising:
a main tube defining an elongated interior compartment;
a wrench head including a workpiece engaging portion and a bar extending therefrom, said wrench head being pivotally secured to a first end of said main tube at a pivot joint, said bar extending into said interior compartment and said workpiece engaging portion extending outwardly from said main tube;
a hand grip located on a second end of said main tube;
one of said main tube and said bar defining a narrowed portion, and a hardened spacer fixedly attached to a first end of said narrowed portion and extending substantially across said narrowed portion to define a gap between a second end of said narrowed portion and a terminal face of said hardened spacer, wherein a length of said gap is configured so that when a rated torque of said torque wrench is exceeded, bending of said torque wrench causes said gap to close and said hardened spacer to bear a force of additional torque.
