ITP Straight Styli Type A features a silicon nitride ball mounted on a rigid carbide stem, designed for dependable, everyday precision probing. With an M2 thread and a compact 20.5 mm overall length, this stylus is built to fit a wide range of standard probing setups and metrology workflows.

• Ball material: Silicon nitride ball for high hardness, excellent wear resistance, and gentle contact with untreated aluminium surfaces.
• Stem construction: Carbide stem delivers exceptional rigidity to maintain measurement accuracy across a variety of dimensions.
• Thread and length: M2 mounting thread and a 20.5 mm overall length for easy integration into common probing systems.
• Product range: Part of the THM2S1003021 family; available in silicon nitride ball options within Ø1.0 mm to Ø5.0 mm ranges, with sizes outside this range obtainable on request.
• Best-use scenarios: Ideal for tactile scanning and coordinate measuring machine (CMM) probing on metal parts, especially untreated aluminium, where stable, low-wear contact is essential.

The combination of a rigid carbide stem and a durable silicon nitride ball yields reliable, repeatable measurements while minimizing wear on both the stylus and the workpiece. The 20.5 mm length keeps setups compact without sacrificing accessibility to tight features, making this Type A stylus a dependable choice for routine inspection, quality control, and precision manufacturing tasks.
