CRAFTSMAN Screwdriver, Slotted, Bi-Material, 5/16 X 6 Inch (CMHT65063N)

5/16-In x 6-in Slotted Bi-Material Screwdriver has a black oxide coating that provides a more precise fit and reduces fastener stripping and cam-out. The polypropylene material, and ergonomic shape of the handle offers twisting force for three different applications; a speed-zone for quick rotation, a torque-zone for added grip in heavy torque applications, and a precision tactile zone for tasks requiring more rotation control.
