The ITP Straight Styli - Type A with Ruby Ball is a precision tactile stylus designed for daily measurement tasks, delivering reliable readings in a compact, durable package. Built for technicians and metrology setups that use standard M4-thread probe heads, it pairs a rigid stainless steel stem with a wear-resistant ruby ball for consistent contact.

• Tip material: Ruby ball tip for high hardness, wear resistance, and stable contact during tactile measurements.
• Thread: M4 threaded shank for secure, compatible attachment to common probe heads.
• Overall length: 13 mm, engineered for use in tight fixtures without sacrificing probing accuracy.
• Stem material: Stainless steel for increased rigidity and durability in daily use.
• Tip diameter options: Ruby ball sizes available from Ø1.0 mm to Ø8.0 mm to suit different surface finishes and measurement needs.
• Design: Straight stylus geometry provides repeatable contact and predictable measurement results across varied surfaces.

The combination of a precise ruby ball and a stout stainless-steel stem translates into stable, repeatable readings across a range of materials and textures. With a compact 13 mm profile and an M4 thread, this stylus integrates quickly into existing probing setups, reducing setup time and minimizing deflection during scans. Ideal for routine QC checks, calibration work, and everyday tactile probing in metalworking, plastics, and assembly environments.
