MAPANA METROLOGY
Thread Gauges (TPG & TRG)
Thread Gauges are precision tools for verifying internal and external threads. TPG (Thread Plug Gauges) check female threads, while TRG (Thread Ring Gauges) measure male threads. Available in Metric, Unified, BSP, NPT, and special profiles, they are manufactured in steel or carbide for durability. Supplied in GO and NO-GO versions, they provide quick, reliable pass/fail results.
Widely used in automotive, aerospace, and engineering industries, these gauges ensure consistency, reduce errors, and maintain global quality standards. Custom thread gauges can also be supplied for non-standard applications, ensuring accuracy and interchangeability in critical assemblies.
Spline Gauges (SPG & SRG)
Spline Gauges ensure accuracy of splined shafts and holes. SPG (Spline Plug Gauges) inspect internal splines, while SRG (Spline Ring Gauges) verify external profiles.
- Available in involute, serration, straight-sided, or custom forms
- Supplied in GO and NO-GO versions for quick, reliable inspection
- Conforming to ISO/DIN standards
Used in automotive, aerospace, and defense industries, they help maintain quality, reduce assembly issues, and ensure smooth power transmission.
ARG & APG – Carbide & Steel
ARG (Attribute Ring Gauges) and APG (Attribute Plug Gauges) are used for dimensional verification of external and internal features.
- Available in carbide for heavy-duty applications or steel for cost-effective use
- Provide durable, accurate, and quick GO/NO-GO inspection
- Manufactured to international standards
They are widely used in automotive, aerospace, and precision engineering sectors to improve inspection speed, minimize rejection, and maintain quality control.
Limit Gauges (Snap, Plug, Ring, Width)
Limit Gauges provide quick, reliable dimensional inspection through GO/NO-GO verification.

- Plug Gauges – internal diameters
- Ring Gauges – shafts
- Width Gauges – slots
Manufactured in steel or carbide, they deliver durability, accuracy, and repeatability, conforming to ISO standards.
Measuring Pins
Measuring Pins, also known as pin gauges, are precision tools for measuring hole diameters, slots, and distances. Available in sets or as individual pins, they are made from hardened steel or carbide with lapped surfaces for accuracy and durability.
Applications include checking hole sizes, calibrating instruments, and verifying dimensional accuracy. Supplied with traceability certificates, they conform to ISO standards.
Slip Gauges (Grade K, 0, 1, 2)
Slip Gauges, or gauge blocks, are reference standards for accurate length measurement. Available in Grades K, 0, 1, and 2, they serve calibration labs, inspection departments, and workshops.
Each block is precision-ground and lapped for smooth wringing and accurate combinations. Manufactured to ISO 3650 standards, they ensure traceable calibration and reliable results.
