The Tekton 1/4 Inch Slotted Hard-Handle Screwdriver has a thick, slotted tip design that withstands high-torque driving. It's machined to the same width as the shaft to fit into narrow recesses. The 8 inch shaft length allows you to reach deep into tight spaces. The handle is refined from a classic square profile and has comfortable contours along the sides that create natural positions for your fingers. Made of durable glass-reinforced nylon, the handle is resistant to extreme temperatures, high impacts, chips, cracks, scratches, fuels, grease, and solvents. We use a molding process that forms the handle around the blade, rather than forcing the blade into a premade handle; the result is a straighter blade that can't twist out.
