McMaster 4973A61 Black-Oxide Steel T-Handle Hex Key 11-Piece Set, Ultra Grip, Standard Length

Keep a selection of top-quality T-handle keys on hand, so you always have the size you need. They’re perfect for cranking screws in large machinery, such as engines and CNC mills. A wide handle gives you maximum leverage, and a long shaft reaches into deep pockets. The shaft is permanently bonded to the handle for a secure hold that won’t break under high torque. To prevent slipping, these T-handle keys are precision manufactured to tight tolerances for an exact fit. Made of hardened steel, they’ll last a lifetime in your tool kit.

Black–Oxide Steel—The dark, matte coating offers minimal corrosion resistance, so these T-handle keys are best for dry environments.

Ultra Grip—Designed for maximum comfort and slip resistance. The plastic coating and textured surface reduce strain and guarantee a secure grip, even when working with wet or oily fingers.
