The ITP Knuckles are precision stainless-steel knuckle joints designed for metrology tasks, offering flexible, angle-ready stylus positioning from 90° to 180°. Built for engineers and technicians who demand reliable alignment in rigid measuring setups, this compact accessory keeps your probe work efficient and accurate.
- Base Material: Stainless steel for strength and corrosion resistance in workshop environments
- Thread Size: M2 thread to fit standard probe interfaces and holders
- Overall Length: 16.5 mm, providing a compact profile for tight workspaces
- Angular Range: Adjustable from 90° to 180° for versatile access to complex features
- Stylus Orientation: Stylus can rotate relative to the machine or workpiece coordinate system
- Compatibility: Designed for use with rigid measuring systems such as CMM setups and other metrology fixtures
With the ITP Knuckles, you can position the stylus exactly where it’s needed—reaching recessed pockets, preparing precise chamfer inspections, or tracing intricate geometries. The 90–180 degree range minimizes the need for reorientation, helping you maintain consistent contact and measurement accuracy. The robust stainless-steel construction supports repeated use in demanding environments, while the compact form and standard M2 threading simplify integration into existing probe configurations.
