The TT20 security Torx bit features a hollow head that fits closely with the screw, helping reduce slipping during installation and removal. The TT rating indicates the Torx head size: a higher value means a larger head, while a lower value means a smaller head. Made from industrial-grade, specially heat-treated S2 steel, the bit offers strength, hardness, and durability. Its sandblasted surface provides a textured finish for improved grip and corrosion resistance. The magnetized, CNC-machined 6-point Torx head securely holds screws vertically, making fastening easier in confined spaces and helping reduce head wear during intensive tightening operations. A special torque-buffer design absorbs vibration generated during use, increasing torque transmission while helping protect the screwdriver head and extend its service life. The 1/4-inch hex shank is suitable for electrical work, mechanical repairs, and furniture installation. Ensure the bit is securely inserted into the power tool chuck before use. Avoid excessive force when tightening screws to prevent damage or slippage. Store the bit in a dry place to help prevent rust and maintain performance.
