Read the full description
The Teng Tools 7 mm insulated flat tip screwdriver is the widest slotted blade in the range, built for the heavy fasteners that hold covers, terminals, and bus-bar connections inside commercial and industrial panels.
Overall length is 266 mm (10.5 in) and weight is 118 g. That combination gives you the reach and leverage needed for large slotted screws while maintaining a balanced feel that keeps wrist fatigue in check during extended panel work.
Insulated construction is critical in high-energy enclosures. This piece is designed to help guard against accidental contact with live conductors, supporting the safety protocols every maintenance electrician follows when working on energized switchgear.
Because it is sold as an individual piece, you purchase only the size you need. If your insulated pouch already covers the smaller tip widths, adding this one rounds out the set without duplicating tools you already carry.
The 7 mm metric designation states blade thickness by blade width. A precise seat in the screw slot means less cam-out, less fastener damage, and faster work on hardware that must meet inspection standards after service is complete.
