The ITP Knuckles stainless steel rotary adaptor is a precision accessory designed for metrology and inspection workflows. It enables precise angular positioning from 90° to 180° while allowing the stylus to rotate relative to the machine or workpiece coordinate system, making it ideal for rigid measuring setups.

  • Base Material: Stainless steel construction for durability and corrosion resistance.
  • Thread: M3 thread for secure attachment in compact tooling environments.
  • Overall Length: 17 mm, providing a compact form that fits tight measurement envelopes.
  • Angular Range: Rotatory adaptor enables any angle between 90° and 180° for flexible probing.
  • Stylus Rotation: Allows the stylus to rotate independently relative to machine or workpiece coordinates, enabling access to difficult geometries.
  • Compatibility: Designed for use with rigid measuring systems to ensure stable, repeatable measurements.
  • Part Number: GIM300004017 for precise ordering and identification.

This adaptor helps you reach otherwise inaccessible features with confidence. By combining adjustable angular positioning with independent stylus rotation, you reduce part handling, shorten setup times, and improve measurement repeatability across repetitive inspections. The stainless steel build stands up to regular metrology use, making it a reliable choice for shop-floor and laboratory environments. Ideal for operators working with rigid CMM setups, fixtures, and probes who need precise, repeatable angles in tight spaces.

Buying experience
Phone requests are handled quickly and without any fuss. The website is easy to use and straightforward to order from. It’s especially helpful that it shows real‑time availability, so we don’t need to call to confirm whether parts will arrive.
