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.
