The integrity of a threaded feature is fundamental to the performance and reliability of a final assembly. At Esteem Manufacturing, we provide absolute verification of all internal and external threads using a comprehensive set of calibrated Go/No-Go plug and ring gages. This is not a subjective visual check, but a definitive physical test to ensure that every thread we machine—from standard UNC/UNF to fine metric—conforms precisely to its specified class of fit, guaranteeing proper assembly and function.

Key Features and Specifications:

• Type: Go/No-Go Thread Inspection Gages

• Styles:

  • Plug Gages: For verifying internal threads (e.g., in a tapped hole).

  • Ring Gages: For verifying external threads (e.g., on a bolt or shaft).

• Standards: Comprehensive sets covering Unified (UNC/UNF) and Metric thread standards.

• Calibration: All thread gages are regularly calibrated and are traceable to NIST (National Institute of Standards and Technology) standards.

• Guaranteed Thread Fit & Function: Our use of calibrated gages ensures that the components we produce will assemble seamlessly with their mating parts, eliminating costly line-down situations caused by improper thread fit.

• Absolute Conformance to Specifications: Go/No-Go gaging provides a clear, indisputable result, verifying that thread pitch, diameter, and form meet the required class of fit (e.g., 2A, 3B) as specified on your blueprint.

• Prevention of Assembly Failures: Properly verified threads prevent common assembly problems such as cross-threading, galling, or loose connections, which can lead to catastrophic failures in the final product.

• Traceable & Documented Quality: Because all of our gages are calibrated and traceable to national standards, we provide a documented and defensible layer of quality control, which is essential for critical applications in aerospace, defense, and medical industries.

• Comprehensive Thread Verification: With an extensive inventory of both plug and ring gages in a wide variety of sizes and pitches, we have the in-house capability to inspect virtually any standard thread your design requires.
