Overview
The JBO 0011 Interchangeable-Head Thread Depth Gauge is a precision metrology instrument engineered for repeatable, traceable measurement of thread engagement depth—specifically the axial distance from a reference surface (e.g., part face or shoulder) to the functional end of a threaded feature’s “go” (full-form) condition. Designed in accordance with ISO 1502 and DIN EN ISO 10587 standards for thread gauging, it operates on the principle of mechanical displacement sensing via a calibrated linear scale integrated into a rigid, thermally stable stainless-steel body. Unlike fixed-head depth gauges, the 0011 employs a modular head interface that enables rapid, tool-free exchange of thread-specific go-end measuring tips—ensuring dimensional fidelity across multiple thread series without recalibration or operator retraining. Its construction adheres to German manufacturing tolerances (DIN 2240), with all critical surfaces hardened and ground to ≤0.2 µm Ra surface finish to minimize wear-induced drift during high-frequency QC inspection cycles.
Key Features
- Modular quick-swap head system compatible with standardized go-end thread plug inserts (M5, M6, M8, M10 metric coarse series per ISO 68-1)
- High-stability anodized aluminum main body with integrated depth stop and zero-reference plane machined to ±1.5 µm flatness
- Linear scale with 0.01 mm resolution and bidirectional repeatability of ±0.02 mm (2σ, per ISO 9001–certified calibration protocol)
- Integrated locking mechanism prevents axial drift during measurement; tactile feedback confirms positive engagement
- Optional wireless depth calibration module (sold separately) supports Bluetooth 5.0 connectivity and real-time data logging to PC or tablet via JBO MetroLink™ software
Sample Compatibility & Compliance
The JBO 0011 is validated for use on externally threaded components manufactured to ISO, DIN, ANSI/ASME B1.1, and JIS B 0205 specifications. It accommodates standard metric coarse threads (M5–M10) with pitch ranges from 0.5 mm to 1.5 mm. Each included go-end insert conforms to ISO 1502 Class 2B tolerance limits and features carbide-tipped contact surfaces rated for ≥50,000 insertion cycles. The gauge meets CE marking requirements under the EU Measuring Instruments Directive (MID 2014/32/EU) and is supplied with a factory calibration certificate traceable to PTB (Physikalisch-Technische Bundesanstalt). For regulated environments, optional GLP/GMP-compliant audit trails and 21 CFR Part 11–enabled electronic signatures are available through the MetroLink™ software suite.
Software & Data Management
When paired with the optional wireless calibration module, the JBO 0011 integrates seamlessly with MetroLink™ v3.2—a Windows-based metrology platform supporting SPC charting (X̄–R, Cpk), batch reporting (PDF/CSV), and automated pass/fail decision logic based on user-defined tolerance bands. All measurement events—including timestamp, operator ID, serial number of inserted tip, and environmental temperature (via integrated sensor)—are logged with immutable audit trail functionality. Data export complies with ISO/IEC 17025 documentation requirements and supports direct import into MES/QMS systems (e.g., Siemens Opcenter, ETQ Reliance) via ODBC or REST API.
Applications
- Final inspection of threaded fasteners in automotive powertrain assemblies (e.g., cylinder head bolts, transmission housing studs)
- In-process verification of tapped holes in aerospace structural components prior to torque application
- First-article inspection for medical device housings requiring precise thread engagement control (ISO 13485–compliant workflows)
- Toolroom validation of thread milling and tapping operations across CNC machining centers
- Calibration lab verification of thread plug gages used in internal metrology processes
FAQ
Can the JBO 0011 measure both go and no-go thread depths?
Yes—the kit includes four interchangeable go-end inserts and four corresponding no-go-end inserts, each independently calibrated and labeled per ISO 1502 functional geometry requirements.
Is recalibration required after swapping measuring heads?
No—each insert is pre-compensated at the factory for thermal expansion and mechanical offset; the gauge’s zero-reference plane ensures consistent datum alignment across all heads.
Does the wireless calibration module support offline operation?
Yes—measurements are stored locally on the module’s embedded memory (up to 10,000 records) and synced upon reconnection.
What is the recommended recalibration interval?
Annual calibration is advised for routine production use; quarterly intervals are recommended for high-volume or critical-safety applications per ISO/IEC 17025 Clause 6.6.
Are custom thread inserts available beyond M5–M10?
Yes—JBO offers bespoke insert development for non-standard threads (e.g., UNF, Whitworth, trapezoidal) with lead times of 6–8 weeks and full metrological certification.
