Raw material plays the most important role in fasteners for reliability & Durability purpose so that we are using the raw material from the OEM approved source. For the batter control we have also developed in-house metallurgical lab in which we are carried out all the inspection & testing parameters which is necessary for the raw material as well as for finish good.

Each raw-material is being tested for its chemical and physical properties like chemical composition, Hardness and MPI (magnetic particles test) Tensile

test & micro examination (Microstructure, Decarburization, grain size, Inclusion rating) according to standard procedure & specifications.

We are also having a Vickers Hardness Tester to measure the hardness on thread zone of the bolt.

For the surface treatment control we have a Coating thickness tester to measure the thickness of coating layer & Salt Spray Test (SST) chamber to evaluate the SST life of surface coating.

We also have necessary instruments which are required for the dimensional inspection & optical sorting machine for 100% dimensional measurement.

For the long life accuracy of the instruments we have developed the standard room in which calibration activities are regulary carried-out for all the instruments & gauges as per the standard procedure & specifications.
