Testing and Inspection Equipment





Quality Control

Main Factory is complete with production facilities
for every standard screws and for special screws
requested by our customers.
 Equipped also with various kinds of testing
instruments, we can meet our customers’ requests and
inquiries about quality and function of screws. And
this enables us to develop special screws for special
requirements and for better function.
 We also carry out our duties as the center of technology
and quality control for our subsidiary factories and for
our overseas factories.
By use of Screw Sorters, which are electronically
controlled, all screws are severely tested and
inspected prior to shipment to our customers.
By use of Torque Analyzer, various tests are carried
out for our technical development and for our
customers’ request.
All drawings in our factory are controlled by CAD
(Computer Aided Design).
 Any revisions of specifications are also under CAD
control.   Being interlocked with QC PRO (Quality
Control Program), CAD can be used for recording
inspection results and for tracing of production processes
from material to shipment.
