Gagemaker BR-2001 | Buttress Runout Gage

The Gagemaker BR-2001 Buttress Runout Gage is a precision API thread inspection tool used to measure thread runout on buttress connections in OCTG (Oil Country Tubular Goods), including casing and tubing.

Designed for API 5B compliance, this gage verifies proper thread pullout and detects premature tool withdrawal during machining—one of the leading causes of connection stress concentration and failure.

If you're serious about thread quality control, connection integrity, and field reliability, this is a must-have inspection tool.

Key Features

• Precision Buttress Thread Runout Measurement
  Accurately measures thread termination to ensure proper load distribution and prevent connection failure.

• API 5B Inspection Compliance
  Supports industry-standard inspection requirements for OCTG threading and gauging.

• 3-Point Contact Design
  Includes two fixed shoes + one TBR (Thread Buttress Runout) contact point for consistent, repeatable readings.

• Standard 1″ & 2″ Contact Point Spacing
  Covers a wide range of buttress thread sizes used in casing and tubing.

• Durable Shop & Field Use
  Built for manufacturing QA, inspection labs, and on-site oilfield applications.

Applications

• OCTG inspection (casing & tubing)

• API thread gauging & verification

• Threading machine setup & validation

• Oil & gas manufacturing quality control

• Field inspection & maintenance

Why Thread Runout Matters

Incorrect buttress thread runout leads to:

• Uneven load distribution

• High stress concentration at thread ends

• Premature connection failure

• Costly downtime and rework

The BR-2001 Runout Gage ensures threads meet specification before they become a problem in the field.
