A handheld screwdriver is manually operated by just one person. Handheld screwdrivers are used when the screw connection has to be flexible and the number of elements to be joined is between 20,000 and 50,000 per year.

For non-manual stationary screwdrivers, the screwdriving unit/spindle is attached to a robot. Stationary screwdrivers are used for high quantities (> 50,000 fasteners/year) and short cycle times. In contrast to handheld screwdrivers, they offer a reliable process: The screw depth monitoring function can be used to accurately calculate how deep the screw has already been installed. This also avoids tilted positioning of the screws. Find an overview of our stationary screwdrivers here: https://www.weber-online.com/en/fixtured-screwdriving-systems/.
