KENFA Product Family
Plug And Ring Gauges
KENFA Plug And Ring Gauges cover metric thread plug and ring gauge routes shown in the catalog for dimensional inspection inquiries. Buyers should identify the thread standard, nominal size, pitch, tolerance class, GO or NO-GO requirement, quantity and calibration or documentation need. Final gauge markings and acceptance criteria must be confirmed before manufacture or quotation.
What should buyers confirm?
Use these fields to narrow the catalog route before KENFA reviews the final model and quotation.
- Thread standard
- Nominal size and pitch
- Tolerance class
- GO or NO-GO requirement
- Quantity and documentation need
How should buyers narrow this family?
Use the starting point that matches the information already available, then confirm the missing fields before model matching.
| Starting point | Confirm | Why it matters |
|---|---|---|
| Replace an existing gauge | Full marking or photo, standard, nominal size, pitch, tolerance class, plug or ring and GO or NO-GO use | The complete marking establishes the controlled inspection requirement more reliably than appearance. |
| Set up a new thread inspection | Internal or external thread, standard, size, pitch, tolerance class, inspection purpose and quantity | Thread form and acceptance class determine the plug or ring gauge route before documentation is reviewed. |
| Request custom markings or documentation | Drawing, acceptance reference, marking format, quantity and required calibration or inspection documents | Non-standard deliverables must be stated explicitly and confirmed before quotation. |
Which matching errors should buyers avoid?
These checks keep a family-level inquiry from becoming an unsupported model or compatibility claim.
- Distinguish plug from ring and GO from NO-GO requirements; these are not interchangeable inspection tools.
- Confirm the exact thread standard, nominal size, pitch and tolerance class rather than using size alone.
- State any calibration, inspection or marking document requirement because it is not implied by a catalog overview.
Buyer questions
Which marking details should be copied into the RFQ?
Copy every visible standard, size, pitch, tolerance and GO or NO-GO marking and attach clear photos of the gauge.
Can a gauge be selected from nominal thread size alone?
No. The thread standard, pitch, tolerance class, internal or external feature and inspection purpose must also match.
How should documentation requirements be handled?
List the exact calibration, inspection, marking or traceability documents needed so availability can be confirmed before quotation.
