- Stem material & rigidity: Carbide stem offers outstanding rigidity to minimize deflection during probing and improve data stability.
- Thread: M2 thread size ensures secure mounting to compatible probe heads and fixtures.
- Overall length: 41.5 mm total length for enhanced reach in tight or recessed measurement areas.
