Torque Wrench

Click-type torque wrenches. Set the figure on the handle and the wrench clicks and releases at that torque — for wheel nuts, cylinder heads, and anything with a figure in the manual.

• Check before ordering: wind it back to its lowest setting after every use. Leaving a torque wrench under spring tension is what puts it out of calibration. Pick the range so your target figure sits in the middle third of the scale, not at either end.
