Suitable for production inspection, incoming quality control and workshop use.

## Long description

FANAR cylindrical thread plug gauge GO/NO-GO 6H M5 is a precision inspection tool designed to verify internal metric M5 threads to tolerance class 6H. The two-piece set includes a GO gauge for acceptance checks and a NO-GO gauge for rejection checks, enabling fast go/no-go assessment of thread size and basic form. The gauge’s cylindrical design is intended for use in production environments, incoming inspection and workshop quality control where quick, repeatable checks are required.
Advantages
This GO/NO-GO thread plug gauge provides simple, unambiguous pass/fail results without the need for complex measurement equipment. Its hardened and ground surfaces ensure durability and consistent verification over repeated use. The compact cylindrical form factor allows access to threaded holes in confined spaces and supports efficient inspection routines on the shop floor or at receiving inspection stations.
Suitable for
Production line thread inspection of internal M5 metric threads
Incoming quality control of threaded components and fasteners
Workshop and maintenance checks for thread wear and conformity
Quick go/no-go verification during assembly and repair
Key specifications
Thread standard: metric M5 internal threads
Tolerance class: 6H
Type: cylindrical GO/NO-GO plug gauge (two gauges: GO and NO-GO)
Use case: pass/fail verification of thread size and basic form
Construction: hardened and ground working ends for wear resistance
How to use
To perform a check, insert the GO gauge into the threaded hole; it should enter smoothly without forcing if the thread is within acceptance limits. Then attempt to insert the NO-GO gauge; it must not fully engage if the thread meets tolerance. Perform checks axially and avoid excessive side-loads that could damage the gauge or the thread. Clean threads of debris and ensure gauges are free of contaminants prior to inspection to maintain reliable results.
Usage recommendations
Store the gauges in a protective case and handle them by non-working areas to avoid nicks on the measuring ends. Periodically inspect the gauges for wear or damage and recalibrate or replace them according to your quality management procedures. Use in conjunction with documented inspection criteria and traceable records for production and incoming quality control.
