ITP Straight Styli Type C Ruby Ball, model FHM502511044, is a precision probing accessory designed for metrology professionals who need rigid, reliable contact points in tight spaces. The 44 mm overall length and M5 thread offer broad compatibility with standard probing systems.

• Thread: M5 thread for broad compatibility with many probing setups
• Overall length: 44 mm to reach into confined areas while maintaining stability
• Shank material: Hardened tungsten carbide for high rigidity and minimal deflection
• Tip material: Ruby ball available in sizes from Ø1.35 mm to Ø2.5 mm for precise, wear-resistant contact
• Body design: Straight, stepped body engineered for secure mounting and repeatable alignment
• Custom sizes: Other sizes can be requested via configurator or by email

This stylus helps you achieve consistent measurements, reduce probing variance, and extend probe life in demanding environments. The rigid carbide shaft minimizes deflection under load, while the ruby ball delivers smooth, repeatable contact on a range of workpiece materials. Its compact 44 mm footprint and standard M5 attachment integrate smoothly with common probing rigs, enabling faster setups, reliable data, and tighter tolerances in GD&T checks, surface profiling, and precision assembly tasks. Ideal for micro-feature measurements, fixture alignment, and intricate geometry checks where accuracy matters most.
