Under Head Surface Inspection
"We need a system that can also inspect the surface underneath the screw head."
….without losing performance nor speed, of course.
This was our latest customer request and therefore our new challenge.
If you tighten the screw with a defined torque, or if the screw also has a sealing function, it is mandatory, to have a specified surface condition under the screw head without any impurities, cracks, or adhesions of zinc.

In some production processes it is not always possible to avoid any defects on this surface. For this, our customer asked for a sorting machine, which is able to do all the well known testing of the fastener and additionally inspect the surface underneath the head of the screw.
We at GEFRA have managed to solve this task based on our standard steel disk machine OPTISORT ST. The modified design enables the inspection system to take a look underneath the head of the screw, during the same single inspection cycle through the machine. For evaluation of the defects, all the familiar tools of our reliable and easy to use inspection software AUTOCONTROL can be used. This new option expands the range of application of the system.
GEFRA offers OPTISORT inspection and sorting machines in two different basic machine types:
- OPTISORT ST with steel ring disc for testing fasteners, screws, blind rivets and long rod-shaped parts
- OPTISORT W with glass disc for testing nuts, washers, rivets and other flat parts
