2000 Series Internal Thread Gage

Industrial verification standards for high-precision fastener inspection. This system ensures repeatable readings and frictionless movement for mission-critical quality control on the factory floor.

Key Benefits

Smooth Precision Movement

Advanced precision linear bearing frame ensures smooth gage movement and frictionless operation.

Interchangeable Elements

Quick change interchangeable gaging elements allow for rapid setup and tool versatility.

Repeatable Readings

Consistent gaging force provides repeatable and trustworthy readings for mission-critical inspection.

Extended Wear Life

Titanium-Nitride (TiN) coated elements provide high hardness and extended wear life in high-volume production.

Internal Measurement

Measures internal pitch diameter and functional size precisely directly on the factory floor.

SPC Compatibility

SPC compatible for process monitoring and real-time data collection to maintain quality standards.

Internal Thread Characteristics Measured

Using interchangeable internal gaging elements, the 2000 Digital Internal Thread Gage can evaluate multiple critical thread features for manufacturing control and inspection.

  • Pitch Diameter (Cone & Vee Elements)
  • Functional Diameter (Full Form Elements)
  • Minor Diameter (Plain Elements)
  • Taper
  • Circularity
  • Thread Form Consistency

  • Production Floor Inspection

System Performance & Durability

The Universal Punch Internal 2-Point Thread Gage frame utilizes advanced precision linear bearings to ensure zero deflection during measurement.

Consistent gaging force and smooth frame movement guarantee repeatable readings throughout the entire measuring range.

All internal gaging elements are Titanium-Nitride (TiN) coated for maximum wear resistance. This coating protects the surface and provides additional hardness that extends element life and improves long-term system stability.

With a master thread setting ring gage, adjustments can be made in seconds to the actual size. This reduces inspection time to a fraction of that required when inspecting parts with traditional GO-NOT GO plug gages.

Internal thread gage used for at-machine inspection of threaded components.

Available Measuring Range
