Durable construction for harsh manufacturing environments
Taptite® Screw Functional Size Inspection
The 9700 Series TRI-LOBE™ Gage enables reliable inspection of externally threaded fasteners manufactured to ANSI/ASME, ISO, NAS, and JIS standards. All systems feature full NIST Traceability and support SPC-Compatible Measurement integration for production environments. It is commonly used for:
•
Functional external thread inspection
•
Taptite® screw diameter verification
•
SPC data-driven inspection systems
•
Fastener manufacturing QA processes
•
Aerospace and automotive threaded fasteners
Typical Applications
Aerospace Fastener Head Inspection
Medical Device Fasteners
Structural Bolting Systems
Clamp Load Verification
Assembly Height Inspection
Incoming QC & Final Inspection
Production Floor Inspection
Consistent Measurement in Production Environments
The TRI-LOBE™ Gage is engineered to deliver stable, repeatable inspection results across a wide range of external fastener diameters. The integrated bearing assembly protects internal components while maintaining smooth and controlled measurement travel. The spring-loaded inspection system ensures consistent contact force between the measuring elements and threaded features, minimizing operator-dependent variation.
