Japan NITTO SEIKO Developed Tamper-proof "Torques® One Way®"

"Torques® One Way®" ensures that the screw can not be loosened and taken out even if the user trys to loosen it. The product was released for sale since November 1, 2013, and has been applied for a patent. Product features are as follows:   1. Unique drive shape for anti-removal: Even if the user tries to use the bit to loosen the screw, the screws ramp shape will make the bit run idle, preventing the screw from removal. 2. Compatible to the previous Torques® bits: No need to use an exclusive tamper-proof bit. The user can use previous bits; therefore, switching to "Torques® One Way®" screws is convenient, lessening the cost of bits and management. 3. Stable torque transmission during driving: The shape of the drive face on the tightening rotational direction remains the same as the previous Torques® screws. Thus, the efficacy of torque transmission during driving remains the same. 4. The ramp of the drive part of the screw can serve as the guide for the bit for easier insertion.
