An insulated slotted screwdriver with a keystone blade for electrical safety
This Wera insulated slotted screwdriver is built for electrical work where protection against electric shock is required. The keystone blade profile widens at the shaft and tapers to the tip for a secure fit in slotted fasteners. It suits electricians and technicians who need a reliable hand tool for live circuits up to the rated voltage.
The multi-component handle provides a comfortable grip and reduces fatigue during extended use. A round blade design allows easy access to recessed screw heads in tight enclosures. Insulation runs along the shaft to guard against accidental contact with energised parts during everyday tasks.
The 3/32 inch tip width determines compatibility with specific small slotted screw heads found in terminal blocks and precision equipment. Users needing larger tip sizes or Phillips profiles must select a different model. This single dimension decides whether the driver matches the fastener.

The 3/32 inch keystone blade engages standard slotted fasteners of that width; the tapered profile seats fully in the screw head to reduce cam-out.
The round blade is 3-1/8 inches long; measure from the screw head to any obstruction to ensure the handle can turn without hitting nearby parts.
Inspect the full length of the shaft coating for cracks or wear; only an intact dielectric layer provides the rated shock protection.
