Insulated screwdriver with a 3/8 inch slotted tip and 13 inch overall length for electrical work
The Klein Tools insulated screwdriver has a 3/8 inch slotted tip and a 13 inch overall length. It is built for professionals who need insulated hand tools when working on live or potentially live circuits. The shank coating provides the insulation barrier required for this type of work. Buyers who need Phillips or Torx profiles cannot use this driver.
This is a passive hand tool so it generates no heat, produces no noise and draws no power during use. The black oxide tip finish resists corrosion while the insulated shank coating remains effective in normal ambient conditions. There are no moving parts or electronics to degrade over time. The tool simply transmits the force applied by the user.
The product carries California Proposition 65 warnings for chemicals known to cause cancer and birth defects or reproductive harm. This disclosure informs users of the regulatory status but does not change the mechanical function of the screwdriver. No bundled accessories or software are included with this single hand tool. The insulated shank is the only feature that alters the working method.

The screwdriver requires no installation; the step users miss is verifying the insulated shank coating is intact before each use on live circuits.
Inspect the black oxide tip and insulated shank regularly; replace the tool if the tip wears round or the insulation shows cracks or cuts.
The black oxide tip finish wears first, reducing grip on fasteners, while the insulated shank coating remains effective unless physically damaged.
