Limit plug gauge 4 mm H7 – TECWERK

Limit plug gauge 4 mm H7 – TECWERK is a precision inspection pin intended for dimensional verification and pass/fail checking of small bores in industrial production and quality control.

• Precision plug gauge, nominal Ø 4 mm H7
• For dimensional inspection and pass/fail testing
• Manufactured by TECWERK, industrial standard

Fast, traceable diameter verification for routine checks

The 4 mm nominal dimension combined with the H7 tolerance grade provides a clear, standardised reference for hole inspection. As a limit plug gauge, the tool serves to confirm whether a bore meets specified limits with a simple fit/no-fit result; this reduces interpretation and secures consistent decisions at the inspection station. The tight specification supports repeatable measurement workflows and helps to maintain documented quality standards.

Streamlined inspection that fits shop-floor processes

Designed for integration into regular quality routines, the checking pin simplifies inspection steps and shortens cycle times by offering an immediate verification method. The compact format of the plug gauge supports handheld checks as well as bench-mounted stations, allowing quick checks across batches without complex set-up. Clear pass/fail outcomes reduce rework and help to keep throughput steady in high-volume or artisanal production environments.

Consistency and recordable control for production confidence

Regular use of this limit gauge contributes to stable process control and traceable inspection results. The H7 designation aligns with common ISO tolerance practices, facilitating communication between design, production and quality teams. As a product from TECWERK, the gauge is appropriate for repeated checks that uphold conformity across lots and support quality documentation required for internal audits.

FAQ

What is the primary use of this limit plug gauge?
The limit plug gauge is used for dimensional inspection and pass/fail verification of 4 mm bores; the TECWERK plug gauge with SKU 2000858584NW provides a direct check of conformity to the H7 tolerance.

What does the H7 tolerance indicate?
H7 denotes a widely used ISO hole tolerance grade; it defines the permissible deviation band for the nominal bore and is applied here to ensure the 4 mm dimension is controlled to standard engineering practice.

How is the plug gauge applied in an inspection routine?
The gauge is inserted into the bore to establish a pass/fail result: correct fit within limits indicates conformity, while a non-fitting result flags further inspection or corrective action.

Is periodic verification required for this gauge?
Periodic verification is recommended to ensure the gauge maintains its specified checking function and supports reliable inspection records for ongoing quality assurance.
