Overview
The Klein JTH6M6 is a 6 inch wrench sized for 6 millimeter fasteners, weighing 2.7 ounces. Its slim, lightweight build points to a nut driver style tool for electrical or fine mechanical work rather than a heavy torque wrench.
A 6 millimeter capacity paired with a 6 inch length and sub 3 ounce weight is typical of a small nut driver or hex wrench rather than a general purpose adjustable wrench. Klein Tools builds much of its line for electricians and low voltage technicians, and a tool this size and capacity fits that niche well, suited to small screws, terminal nuts, and panel hardware.
