Now we update some test items for the bolts ,screws and studs.with the test standard.

Kinsom test will follow all this when we control in house or in the third party ,SGS,CTI or required by clients,


Kinsom can take control those following items in house:

  1. Go/no go plug gauge test (all test tools are calibrated by professional third party every year)

  2. Dimension

  3. Proof load test

  4. Torsional strength test

  5. Rockwell hardness

  6. Superficial rockwell hardness

  7. Vickers hardness

  8. Brinell hardness

  9. Micro hardness

  10. Salty spray Test

  11. Tensile strength

  12. Hydrogen embrittlement test
