Go/No-Go Pin Gauges in Silicone Holes: Force and Functional Fit

Measurement, Quality and Procurement
Key point: A soft bore can expand around a pin. Define insertion force and state; pushing a gauge through does not establish free bore size or reliable cable fit.

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.

StepAction and evidence
1 · Define the decision targetSeparate free diameter, through-hole continuity and cable function.
2 · Standardize pin useAgree tip, direction, force or a no-forcing rule. Never force a no-go gauge through.
3 · Compare actual functionUse 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.
