TORX PLUS® insert Screw
TORX PLUS® Cutting Tool Screws are designed for the world of indexable tooling, where a screw is tightened and released constantly as inserts are rotated or replaced. The fastener is produced from high-performance alloy steel using efficient deep-hole machining and precision thread-rolling, a combination that balances hardness for wear resistance with toughness for impact durability.
The drive system is central to performance. The TORX PLUS® profile engages the driver over a broad, nearly vertical contact area, which allows significantly higher torque transfer than conventional recesses. Just as importantly, it prevents the cam-out and socket stripping that make tool screws fail prematurely when they are used hard and often.
The result is consistent fastening precision and extended service life across repeated tool change cycles — fewer stripped screws, less downtime and a machining process that holds its accuracy.
Extensively used in CNC machine tools, precision milling cutters and indexable tooling systems, these screws suit high-speed, high-vibration environments such as automotive component machining, aerospace precision milling and mould manufacturing.
They provide the core fastening reliability on which tool-holder accuracy and cutting consistency depend.
