Precision in Flight: How DIATEST Taper Gauges Are Elevating Aerospace Manufacturing
Estimated reading time 2 minutes
In aerospace, precision isn’t optional — it’s mission-critical. From fuselage panels to engine casings, every component must meet the highest standards of accuracy and reliability. That’s why leading aerospace manufacturers are turning to DIATEST Taper Gauges for rivet hole inspection.

🔍 Why Rivet Hole Inspection Matters
Rivet holes are small but vital. A misaligned countersink or incorrect depth can compromise structural integrity, leading to costly rework or, worse, safety risks. Aerospace standards typically require a 100° countersink, and verifying this with precision is essential.
🛠️ DIATEST’s Solution: The 105° Taper Gauge
To meet this challenge, DIATEST developed the IKT105-1-OS-DI Taper Gauge, featuring a =<105° measuring cone — a near-perfect match for the 100° chamfer used in aerospace rivet holes. This ensures accurate, repeatable measurements and helps manufacturers maintain compliance with strict quality standards.
✅ Key Features:
- Digital dial indicator for high-resolution readings
- Compatible with setting masters for traceable calibration
- Proven performance in comparison with industry alternatives

🧰 Aerospace Applications
DIATEST Taper Gauges are used in:
- Fuselage assembly: Ensuring flush rivet seating
- Wing panel fabrication: Verifying countersink angles
- Engine nacelle construction: Inspecting fastener holes in high-heat zones
- Landing gear components: Measuring depth and bore in fatigue-critical parts
🔧 More Than Just Taper Gauges
DIATEST offers a full suite of aerospace metrology tools:
- SO-IKT1202: Detects burrs or surface elevation
- SO-IKT1210: Measures rivet hole depth
- SO-ZU0418: Combines bore and depth measurement
- SO-IKT1033: Measures rivet head height
- SO-IKT0310.126: Uses spherical contact for chamfer geometry inspection
These tools are already in use by major aerospace manufacturers, including Airbus suppliers.
