Klein Tools 6254 1/8-Inch Slotted Precision Screwdriver, 4-Inch Shank

No. The Klein Tools 6254 precision screwdriver is not insulated and will not protect against electrical shock. De-energize the circuit before using it. If you need to work on or near energized conductors, use a screwdriver rated and marked as insulated instead.

The 6254 has a 4-inch shank and a 7.5-inch overall length, so it reaches about four inches past your hand into a recessed pocket. The shank is slim (the tip is 1/8 inch, 3.2 mm) and the handle is only 0.55 inch in diameter, so it works down tight openings on thermostats, small appliances, and electronics housings.

No, the tip is not magnetized. For small fasteners in a vertical or overhead position you will need to start the screw by hand or use a separate magnetizer. The rotating cap on the end lets you steady the driver with your index finger while turning with the other hand, which is what gives you control on tiny screws.

For slotted screws, yes, within a range. A 1/8-inch (3.2 mm) blade suits eyeglass hinge screws, small appliance covers, and electronics chassis screws. It will cam out or damage the slot on anything much smaller or much larger, and it does nothing for Phillips, Torx, or hex fasteners. Confirm your fastener is a straight slot before ordering this one.

Klein Tools 6254. It ships as a single driver, not a set, weighing 0.08 lb. If you are standardizing a tool crib or building out service kits, that MPN is what to put on the requisition.

The shaft and tip are S2 steel, heat treated and precision-machined for strength, with nickel chrome plating for rust resistance. It is built for turning, not prying: Klein warns against using it to pry or chisel, which is how precision tips get snapped.

Two markings. The 6254 carries a blue color-coded ring identifying the tip type, and the oversized end cap is marked with the tip size so you can read 1/8-inch slotted off the top of the driver while it sits in a pouch or rack. The handle itself is black and yellow.

It is a Cushion-Grip handle in CA/TPE, 3.5 inches long and 0.55 inch across, so it sits in the fingertips rather than the palm. The free-spinning cap on the butt end is what carries the downward pressure while your fingers spin the barrel, which is the whole point of a precision driver versus a standard one.
