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:
Go/no go plug gauge test (all test tools are calibrated by professional third party every year)
Dimension
Proof load test
Torsional strength test
Rockwell hardness
Superficial rockwell hardness
Vickers hardness
Brinell hardness
Micro hardness
Salty spray Test
Tensile strength
Hydrogen embrittlement test
