Scope and common interpretation errors
For small cable and locating holes, without universal gauge dimensions.
Pin tip, finish and force alter deformation. Excess insertion can enlarge or damage the opening; gauging and cable retention are related but distinct evidence.

Turn the review into recorded checks
| Step | Action and evidence |
|---|---|
| 1 · Define the decision target | Separate free diameter, through-hole continuity and cable function. |
| 2 · Standardize pin use | Agree tip, direction, force or a no-forcing rule. Never force a no-go gauge through. |
| 3 · Compare actual function | Use real cable diameter and assembly conditions to check retention, damage and required sealing. Segregate destructive samples. |
A comparison to avoid misinterpretation
If a no-go pin passes only with substantial force, record it under the predefined rule rather than applying arbitrary force to create a chosen result. Add low-deformation measurement if needed.

Frequently asked question
Does a passing bore gauge establish correct hole position?
No. Size and position need corresponding inspections.
