Klein Tools 6337INS Insulated Screwdriver Crosspoint #3 7 in Round hand screwdriver

Insulated Crosspoint #3 Screwdriver

This Klein Tools 6337INS insulated screwdriver is built for electricians and technicians who work on or near live circuits. The single-ended Phillips #3 tip handles larger fasteners common in panel work and heavy-duty terminal blocks. A black-oxide finish on the tip resists corrosion while the insulated shank provides a protective barrier up to the rated voltage.

Insulation rating and tip constraints

The insulation is tested to a specific voltage standard that limits the tool to circuits within that rating; exceeding it defeats the protection. The fixed #3 tip cannot be swapped for smaller profiles, so it will not fit #1 or #2 recesses without risking cam-out or damage. The round shank offers no flats for wrench assistance when extra torque is needed.

Check voltage rating and tip fit

Before ordering, verify that the tool’s insulation rating matches the maximum voltage you will encounter on the job. Confirm that the fasteners you drive are Phillips #3, as using this tip on smaller sizes can strip heads. The product carries a California Proposition 65 warning for chemicals known to cause cancer and reproductive harm.
