The ITP Straight Styli - Type A with Ruby Ball (M3 Thread x 42mm Overall Length) is a precision measurement stylus designed for production and inspection environments. Its carbide stem and integrated break point protect your measuring system from accidental collisions while delivering reliable, repeatable contact with tested surfaces.

• Thread: M3 threaded connection for secure, quick attachment to compatible probes and fixtures.
• Overall Length: 42 mm from base to ruby sphere for reaching into tight measurement pockets.
• Ruby Ball Diameter: High-quality ruby balls available in Ø4.0 mm to Ø8.0 mm to suit a range of probing needs.
• Stem Material: Carbide stem provides stiffness, wear resistance, and dimensional stability during repeated use.
• Integrated Break Point: Built-in break point absorbs shocks and helps prevent damage to the measuring system in production settings.
• Geometry: Type A straight design optimized for consistent contact and repeatable measurements.
• Customization: Other dimensions can be requested via the configurator or by e-mail.

In production and metrology workflows, this stylus offers dependable performance: the hard carbide core maintains precise contact geometry, the ruby ball delivers a smooth, enduring probing surface, and the protective break point reduces downtime from accidental bumps. The option to choose ball diameters from 4.0 to 8.0 mm expands use cases from fine-feature probing to broader contact areas, while the standard 42 mm length suits many fixture layouts. If your setup requires a specific dimension beyond the standard, consult the configurator or contact support for tailored options. This stylus is well-suited for high-precision QA, assembly inspection, and routine calibration tasks on demanding production lines.
