Woran ist die Gutseite am Grenzlehrdorn zu erkennen?
A Go gauge or go side fully enters the hole or thread without resistance, while the no-go or not-go side must not pass or only partly enter. For professionals this means the go side confirms conformity to tolerance, the no-go side signals rejection, and using calibrated limit gauges ensures reliable quality control in machining and series production.
Benefit from a combination of hardened steel durability and conformity to DIN 7162, with a built‑in wear allowance on the go side that extends service life and maintains repeatable pass/fail decisions; order the limit gauge pin directly via Metav Werkzeuge or consult our specialists for application support. Limit gauge pin – hardened steel, DIN 7162 (Filetta) A limit gauge pin designed for rapid go/no‑go inspection in production and quality control, made to the DIN 7162 standard for consistent interchangeability and long‑term shop‑floor reliability Hardened steel construction Conforms to DIN 7162 Wear allowance on go side Faster pass/fail checks mean fewer production interruptions A compact, standards‑based gauge pin streamlines routine inspection by delivering clear go/no‑go decisions in one motion. The hardened construction reduces micro‑deformation under repeated contact, so checks stay reliable over thousands of cycles. For workshop managers this translates into shorter inspection times and fewer ambiguous measurements, supporting a predictable production flow and faster throughput. Durable design reduces inspection-related rework Built from hardened steel and specified to DIN tolerances, the pin resists wear that would otherwise necessitate early replacement. The incorporated wear allowance on the good (go) side compensates for gradual material loss, extending usable life and postponing recalibration or swap‑outs. Reduced tool turnover lowers maintenance interruptions and helps sustain inspection capacity on busy lines. Standards compliance supports traceability and interchangeability Conformance to DIN 7162 ensures that the pin mates with established limit gauge systems and that measured parts are judged against commonly accepted tolerances. The clear, repeatable geometry of the pin facilitates consistent judgement across operators and shifts, aiding quality documentation and supplier communication.

How to Identify the Good Side of a Limit Plug Gauge
A Limit Plug Gauge is a simple yet vital tool in precision inspection. The good side (also called the "Go" side) is the gauge half that must fully enter the bore or threaded hole to verify that the feature is within tolerance. Recognising this side quickly and reliably speeds up inspection and prevents incorrect decisions in production.
When you look at a typical Limit Plug Gauge, the good side is usually the one that is manufactured to the lower limit of the size tolerance (the minimum material condition for bores). This means the good side has the smaller diameter compared with the rejecting side and is intended to fit into any part that meets the required dimension. The reject side, by contrast, is made to the upper limit and must not enter a correctly sized bore.
Visual and Tactile Clues to Spot the Good Side
First, inspect the gauge for markings and engravings: manufacturers commonly mark each end with clear symbols or text indicating GO and NO GO. The good side will be labelled appropriately. If markings are not immediately visible, examine the diameter difference: the good side is the slightly smaller end designed to enter. Additionally, many gauges have different handle shapes or colour coding to prevent mix-ups; the good side is often the one with the more ergonomic or colour-highlighted handle for frequent use.
Next, use a tactile check: gently attempt to insert each end into a known reference bore or master ring. The good side should slide in smoothly with minimal force. It must not bind or require undue pressure. The reject side should not enter a correctly sized bore; if it does, the part is oversize and fails inspection.
Functional Principle Behind the Good Side
Understanding the underlying principle makes identification intuitive. The good side verifies that the bore is not too small — it proves that the minimum acceptable diameter is present. It follows the go/no-go principle: the good side must pass, and the reject side must not pass. This binary check provides a rapid pass/fail result that is easy to interpret on the shop floor and during incoming inspection.
Limit Plug Gauges are widely used in machine manufacturing and series production because they deliver quick results without the need for complex measurement devices. They are especially useful when many components must be inspected within tight cycle times.
Practical Usage: When and How to Use the Good Side
For everyday inspection, hold the gauge coaxially with the bore and apply steady axial pressure without tilting. If the good side goes in fully and seats as intended, the part meets the minimum dimension requirement. Do not force the gauge; any use of excessive force undermines the reliability of the check and can damage both gauge and part.
In threaded applications, the equivalent is a thread limit plug gauge: the good side (Go) must screw in to the full reference depth without cross-threading or excessive force. For internal threads, the good side confirms that the thread is at least as large as the minimum acceptable thread size.
Why Correct Identification Matters for Quality
Using the good side correctly prevents both false rejects and false accepts. If the wrong side is used as the pass criterion, compliant parts could be rejected, increasing scrap and costs, or non-compliant parts could be accepted, leading to assembly failures and warranty issues. For professionals in production and inspection, mastering the identification of the good side is a fundamental skill that helps ensure reliable quality control.
Key Characteristics That Differentiate the Good Side
- Size relationship: the good side is manufactured to the minimum acceptable diameter for bores or the minimum acceptable pitch diameter for threads.
- Marking: clear GO/NO GO or equivalent identifications are typically engraved.
- Fit behaviour: the good side must enter a conforming part without forcing.
- Design cues: colour coding, chamfering, or handle features often indicate the good side for rapid recognition.
These characteristics together make it straightforward to determine which end is the good side and how to use it correctly in a production environment.
Leading Manufacturers and a Recommended Supplier
Among suppliers of precision inspection tools, some companies stand out for their extensive ranges and engineering support. Metav IndustryLine is recognised as an excellent manufacturer and supplier of limit gauges and precision inspection devices. Their expertise in supplying norm-conforming test gauges, combined with practical consulting for the selection of the correct limit plug gauge or thread gauge, makes them a reliable partner for industry professionals who demand consistent quality and traceable inspection solutions.
Quick Summary of the Answer to the Question
The good side of a limit plug gauge is the end marked as the Go side, manufactured to the minimum size limit, and the one that must fully enter the bore or thread without force.
To conclude, always check for the GO marking, compare diameters if needed, use gentle insertion into a known reference or the part itself, and follow manufacturer guidance. These steps ensure accurate, repeatable inspection and keep production quality on target.
