Martin SDS6-1 Square Screwdriver, 6 in OAL, Zinc Plated

Square shank screwdrivers have rust and corrosion resistant finish chrome vanadium steel blades and user friendly industrial design fluted plastic grips. These are special purpose tools with a variety of lengths and tip configurations designed to insert, remove, loosen and tighten screws which require a greater amount of torque. The square shape allows you to quickly and conveniently apply an adjustable, or other style, wrench to the shank of the screwdriver for additional torque. Always match the appropriate screwdriver tip to the specific size and type of screw.
