The keystone-tip blade measures 3\/8 inch wide and 12 inches long, giving it the extended reach required for electrical panels, HVAC equipment cabinets, and mechanical assemblies. Overall length is 16-3\/4 inches. The round shank allows a wrench to be applied for extra torque when driving stubborn fasteners. An ergonomic handle, measuring 4-3\/4 inches in length, reduces hand fatigue during sustained use.\u003c\/p\u003e\n\u003cp\u003eThis screwdriver is suited for electricians, HVAC technicians, plumbers, and general maintenance professionals who regularly work inside deep enclosures or equipment cabinets. The extended blade length makes it well-suited for reaching fasteners that shorter screwdrivers cannot access. It is a single-piece hand tool requiring no power source, making it appropriate for job sites where power tools are impractical or restricted. The keystone tip is a standard profile compatible with a wide range of slotted fastener heads found in trade and industrial applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKeystone tip profile for broad slotted fastener engagement\u003c\/li\u003e\n  \u003cli\u003e12-inch blade length provides extended reach into deep enclosures\u003c\/li\u003e\n  \u003cli\u003eRound shank allows wrench assist for high-torque driving\u003c\/li\u003e\n  \u003cli\u003eErgonomic handle design reduces hand fatigue during prolonged use\u003c\/li\u003e\n  \u003cli\u003e16-3\/4 inch overall length for total leverage and control\u003c\/li\u003e\n  \u003cli\u003eBlade thickness of 0.05 inches for precise slot fit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard slotted screwdriver for use with slotted fasteners across residential, commercial, and industrial trade applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is intended for use by qualified tradespeople familiar with hand tool safety practices.
