INSIZE precision push gauge SPRAWDZIAN TLOCZK. GLADKI MSBA 12 H7 (MPN 4124-12)

INSIZE precision push gauge SPRAWDZIAN TLOCZK. GLADKI MSBA 12 H7 is a cylindrical smooth probe engineered for tactile verification of hole diameters and fit clearances. The MSBA 12 H7 model is intended for quick pass/fail checks and precise dimensional confirmation in inspection, assembly and calibration tasks. Designed for use on inspection benches and in workshop environments, this push gauge helps confirm whether holes meet the H7 tolerance class and supports routine quality-control workflows.

Advantages

The smooth cylindrical design provides reliable contact with minimal interference, enabling repeatable tactile checks. Manufactured to tight dimensional standards, this push gauge offers consistent fit verification for holes nominally matching a 12 mm H7 tolerance. Its compact form factor eases handling for bench or in-line inspections, and the simple push-pin operation reduces measurement time while preserving measurement integrity.

Suitable for

• Pass/fail inspection of holes with H7 tolerance
• Workshop quality control and production sampling
• Assembly verification where precise pin size is required
• Calibration checks and fixture setup on inspection benches

Key specifications

• Probe shape: smooth cylindrical pin
• Nominal diameter: 12 mm designed for H7 tolerance class
• Intended use: push/pin gauge for go/no-go style verification
• Material: hardened measuring steel (typical for precision gauges)
• Application environment: bench inspection, workshop quality control

How to use

Introduce the smooth probe gently into the hole to be checked and apply axial push force until contact is made. For a pass condition, the gauge should enter fully without binding when the hole meets the H7 tolerance. If the gauge resists or fails to enter, the hole may be undersized or out of tolerance. Use consistent insertion speed and orientation to maintain repeatability. Record results immediately in inspection logs when performing batch sampling or routine checks.

Usage recommendations

Handle the push gauge with clean hands or gloves and avoid impacts or drops that can alter the probe diameter. Store the gauge in a protective case when not in use and perform periodic calibration checks against a traceable standard to ensure continued dimensional accuracy.
