The Klein Tools Keystone Screwdriver features a precision-machined 5/16" tip for an exact fit on medium flathead fasteners, making it well-suited for load centre covers, conduit fitting slotted screws, and general electrical assembly work where a mid-size keystone tip is required. Its 6" heat-treated round shank includes a hex bolster for wrench-assisted turning, delivering extra torque when fasteners are tight or corroded. The Cushion-Grip™ handle with internal anti-twist flanges provides all-day comfort and a secure grip, with Tip-Ident® for instant tip orientation on the job.
