Infrastructure

Kadevi Fasteners Division is equipped with :

a) Four Station of Bolt Making Machinery consisting of header machine/Trimming/Thread Machine
b) Four Station of Nut forming machine and ten nut tapping machines tomanufacture M8 to M24 and DIA 5/16” to 7/8” respectively.
c) Two Galvanising Plants.
d) Two sets of automatic Bolts, Nuts assembly machines.
e) In house workshop for Tools making.

Wire Drawing Machine :

The raw material received in the form of coils/rods
are subjected for cleaning in HCL and Phospating
process. Subsequently the coils are fed into
drawing machine and will be drawn to exact size
required to ensure roundness of the coil rod.

Nut Forming Machine :

The required size of coil will be fed into the
machine which are fully automatic and
finished product of nuts (blank) are formed
in 5 stage operation. The present production
range is from M8 to M24 with four stations of
machinery installed.

Nut Tapping Machine :

The nuts are tapped by automatic hopper nut
Tapping machines with double spindle for the
most accurate and utmost quality threading. We
have 10 nut Tapping Stations.

Bolt Header Machine :

The required coil is fed into the fully automatic bolt
head forming machine. The output is in the form
of round head with required length of bolt. We are
equipped with four stations of bolt making
machines manufacturing different sizes from M8
to M24 & DIA ½” to 1”.

Bolt Trimming Machine :

The semi finished bolts received from the header
are fed into this machine which converts the round
head into hexagonal head and the length of the
Bolt is trimmed to the required size. The bolts are
automatically fed by a conveyor system.

Bolt Thread Machine :

The semi finished bolts received from the
trimming machine are fed into this machine which
forms threading 9half/full). The bolts are
automatically fed by a conveyor system.

Galvanising Plant :

The machined bolts & nuts are cleansed by a chemical
process vide pickling, cleaning, fluxing and finally sent for
pre-heat treatment. After chemical process bolts & nuts
are dipped into the galvanising kettle at well maintained
Temperature of 450 Degrees. Out hot dip galvanising
plant is a state of the art plant confirming to IS
Specifications.

Assembly Machine :

The galvanized bolts & nuts are fed into the assembly
machine separately through conveyer system which
automatically assembles the nuts to the bolts to a
prescribe length to ensure that proper mating of the bolts
& nuts.

Packing :

We pack our bolts & nuts in a standard pack of 50
kgs in double lined gunny bags with polypropylene
exclusively developed. These bags are very
robust in construction and every bag is filled 50
kgs of fasteners duly assembled with a electronic
weighing machine.

Quality Assurance :

Our strong focus on manufacturing process and quality assurance enables us to
supply high quality material and delivery cost effective solution. Our manufacturing
practice has been technology driven and to stay at the fore front of innovation, we
continuously invest in Research and Development.

Quality Assurance :

Our quality management system ensure high level of quality by inspection of incoming material and
mandatory quality checks at every stage throughout the manufacturing process. Our highly equipped
quality and testing facility enables us to deliver superior quality products confirming to
Indian/International standards and achieve total customer satisfaction.

In Process inspection :

Online inspection will be carried out at every stage with suitable jigs & gauges to ensure the required
specifications as defined in the standards.

Final Inspection :

Final Inspection check is carried out to ensure that Product Quality is in conformance with specified
requirements.

Inspection and Test Reports/Records are maintained to establish that the product has passed inspection
and testing in accordance criteria defined in the Inspection and Testing Procedures. Records are
maintained for calibration and verification of monitoring and measuring equipments. We are ISO 9001-
2008 certified for well maintained Quality Management Systems by NQA-UKAS.

Test Equipment :

a) Emission Spectrometer for material analysis
b) Universal Testing Machine for Tensile/ Compression/Shear Tests.
c) Hardness Testing Machine for Checking Hardness (Brinell & Rockwell).
d) Profile Projector for measuring the thread profile/contours etc..
e) Other measuring Instrument, Gauges etc.. to confirm to Specification & Drawings.
