M3 XXT (637)
Styli with M3 XXT thread were developed especially for ZEISS VAST XXT measuring probes. ZEISS M3 XXT styli have a much higher rigidity than conventional M3 styli. This stiffness is achieved through a 1 mm larger diameter of the XXT adapter with a titanium allow base body. This alloy also makes the adapters significantly lighter than steel, non-magnetic and corrosion resistant. In the M3XXT range, different stylus elements (sphere, ball cylinder etc.) made of different materials and different shaft designs (shape, material) are available.
