Precision Engineered for Power Transmission Threads

The trapezoidal thread gauge is engineered to verify pitch diameter, flank angle, and functional fit with extreme accuracy, ensuring that power transmission threads meet exact dimensional requirements. This minimizes assembly failures, backlash issues, and premature wear in critical mechanical systems.
Designed specifically for trapezoidal threads used in motion and load transfer, these gauges confirm correct thread geometry essential for lead screws, jacks, and actuators, ensuring smooth movement and reliable force transmission under continuous operational loads.
The measuring threads are precision lapped and polished to achieve ultra-low surface roughness, reducing friction during gauging and preventing false readings caused by surface irregularities or burrs on the component being inspected.
Dual-ended or paired GO / NO-GO configuration allows rapid acceptance or rejection of components, enabling inspectors and machine operators to maintain consistent quality control without requiring complex measurement interpretation.
Advanced heat treatment and stress-relief processes ensure dimensional stability, allowing the gauge to maintain accuracy even when used in fluctuating shop-floor temperatures, aligning results closely with inspection-room standards.
Each gauge is permanently laser marked with size, pitch, standard, and identification details, ensuring easy traceability, eliminating confusion during inspections, and supporting ISO-compliant quality documentation systems.
A broad standard size range combined with custom manufacturing capability allows the gauge to meet both common industrial requirements and specialized applications, making it suitable for diverse engineering and manufacturing needs.
Designed and manufactured in line with DIN and ISO trapezoidal thread standards, the gauge ensures compatibility with globally accepted specifications, supporting export-oriented manufacturing and international quality audits.
