The Ideal Twist-a-Nut is a 21-in-one multi-bit, dual-ratcheting screwdriver that has the four bits pre-loaded into the driver shaft with an additional 12 specialty bits securely stored for quick access within the handle. Compatible with 1/4", 5/16" and 7/16" nuts, the Twist-a-Nut is built around an all-metal, 28-tooth ratcheting mechanism that delivers 225 lbs of torque. The ratchet provides clockwise, counter-clockwise and locked ratcheting action. The handle has a two-part dual durometer grip, comprised of soft, black overmolding and a harder, high-visibility yellow reinforced propylene to assure stability and toughness. Grip materials are resistant to water, perspiration, oil and chemicals.
