Gagemaker T072 API Contact Points for Lead & Taper Gauges | 0.072″ Diameter | 8 TPI | Threaded Shank

The Gagemaker T072 API Contact Point is a precision carbide-ball contact point designed for API tubing and casing lead and taper gages used in OCTG thread inspection.

Manufactured for 8 round API tubing and casing connections, the T072 features a 0.072″ ball diameter and threaded shank configuration, delivering accurate and repeatable measurements for thread lead, taper, and addendum inspection applications.

Built for use with Gagemaker inspection systems, the T072 is widely used in API Spec 5B thread inspection, oilfield manufacturing QA/QC, and OCTG inspection operations.

Why the T072 Matters

Accurate contact points are critical for reliable thread inspection.

Worn or incorrect contact points can lead to:

• Incorrect taper measurements

• Lead inspection errors

• Thread rejection issues

• Connection mismatch in the field

The Gagemaker T072 helps maintain precise inspection standards across API tubing and casing operations.
