Thread Gauge Gimex M52x2 6G MPN 315.252.7 — Go/No-Go Ring Gauge for Metric Threads

Gimex go/no-go ring thread gauge M52x2 6G is a precision inspection tool designed to verify external metric threads with a nominal diameter of 52 mm and a 2 mm pitch. The gauge combines a "go" end and a "no-go" end in a single ring to provide a fast, repeatable check of threaded shafts and fasteners against tolerance class 6G. It is intended for use in workshop quality control, production inspection and incoming part verification where a quick determination of thread conformity is required.

Advantages

The two-ended ring design enables immediate go/no-go assessment without the need for adjustments or auxiliary fixtures. Manufactured to tight dimensional standards, the gauge offers reliable repeatability and long service life when used and stored correctly. Its compact ring form allows straightforward handling and rapid checking directly on production lines or at receiving inspection stations. The clear distinction between go and no-go ends reduces operator uncertainty and speeds up throughput in inspection routines.

Suitable for

• Workshop quality control of threaded shafts and studs
• Production line inspection of externally threaded parts
• Incoming goods inspection for fasteners and components
• Maintenance checks where quick verification of thread conformity is needed

Key specifications

• Thread form: metric ISO thread, external
• Nominal diameter: 52 mm
• Thread pitch: 2.0 mm
• Tolerance class: 6G (go/no-go limits matched to this class)
• Design: two-ended ring gauge (go and no-go ends)
• Material: hardened metal appropriate for long-term inspection use

How to use

To inspect an external thread, place the appropriate end of the ring gauge on the threaded area and rotate slightly by hand. The "go" end must enter and run onto the full length of the thread without binding; the "no-go" end must not fully enter if the thread is within the specified tolerance. Avoid forcing either end; a light hand fit is the intended use. Perform checks on clean, dry threads and ensure chips, burrs or coatings are removed prior to inspection. Record results according to your quality control procedures.

Usage recommendations

Use the gauge in a clean, dry environment and store it in a protective case when not in use. Periodically verify gauge condition and calibration against reference standards, and replace if wear or damage affects fit. Do not use the gauge as a machining tool or for applications other than thread verification.
