PG-6001-M | Internal Functional Size Thread Inspection Gage | Functional Size Gages

Precision • Metric Readout • Professional Thread Inspection

The Gagemaker PG‑6001‑M is a high‑accuracy internal thread roll gage designed to measure pitch diameter variation in internal threaded components with exceptional repeatability. Equipped with a metric dial indicator, this model provides clear, precise readings ideal for international machining, QC labs, and oilfield inspection environments.

Part of the trusted PG‑6000 series, the PG‑6001‑M helps operators quickly detect thread wear, deformation, or machining deviations—ensuring every component meets strict dimensional and API‑related standards.

PG-6001-M Internal Pitch Diameter Gauge (V & Acme) Metric Indicator

Internal Pitch Diameter (6” to 24″ Diameters)

The ball pitch diameter gages or “GO/NO GO” gages indicate the pitch diameter size of the product’s internal threads.

The gages are adjustable within a size range and use interchangeable contact points to measure different pitch threads.

Setting dimensions for the pitch diameter gages are provided by the TDWIN software.

Gages require setting with either a MIC TRAC™ or other means (i.e. gauge blocks, micrometer, standard, etc.).
