Marposs Optoflash: improving precision inspection of screws

Ever wondered why the fasteners manufacturing industry is rapidly switching to optical systems for precision inspection of screws?


This trend has a clear reason at the basis. In the fasteners industry, huge production volumes and large part variety coexist. Fastener’s production is mostly executed in a "Make-To-Order" strategy, so each single production line is subject to frequent switches from a fastener model to a new one.

All these aspects have a direct impact on the inspection equipment and their necessary features to satisfy the processes.


Only measurement systems like Marposs Optoflash – which is fast, precise, and flexible at the same time – can match the actual demanding requirements of the Fasteners industry.


Optoflash: complexity and variety of fasteners inspection made easy

Optical inspection is winning for fasteners, as it enables a large number of quality controls on the same part.

For instance, small features, which are usually difficult to check with traditional systems, are easily inspected through Optoflash high-resolution images.

The optimized fastener algorithms are able to inspect fasteners over 360° and calculate their exact features over multiple inspection angles.


Through images, threads are validated in each of their peculiarities:

  • Thread external, internal, pitch diameter;
  • Pitch size and profile angle;
  • Thread total length, linearity, concentricity.


An effective support for operators

With image feedback on each inspected unit, operators can quickly validate the output of the measurements and easily diagnose non-compliances, through visual analysis of the part, directly on Optoflash interface.


Usability is a crucial feature of the product. Optoflash software is specifically designed to enable a fast addition of new control programs for new parts. The operator just needs a few minutes to work through a new part program and no training is required.
