Specifications
Measuring instruments
We have a wide range of measuring instruments and thread gauges, calibrated in a NABL accredited laboratory.
Our instrument hub includes external, internal and depth micrometers along with screw thread micrometers, digital as well as dial vernier callipers with digital hook depth vernier, digital height gauges, bore gauges and lever type dial gauges.

Extra facilities
Slip gauge box, surface roughness comparator with No. 130 composite set, and a surface plate of 900 x 600 mm of micro flat datum are available.
Traceability and testing
To maintain traceability of raw material, we perform raw material testing only in a NABL accredited laboratory, along with our standard defined colour coding system procedure.
We perform Dye Penetrant Test (DPT) and Magnetic Particle Inspection (MPI) in non-destructive testing, whereas for raw material verification we pursue:
- Spectro / Chemical Analysis
- Physical / Mechanical Analysis
- Hardness Analysis
- Micro and Macrostructure Analysis
- Ultrasonic Testing (UT)
