Yes — our brushless electric screwdrivers are suitable for use in an ISO Class 5 cleanroom (formerly Class 100 under Federal Standard 209E). Choosing the right screwdriver is critical because particle generation from tools is one of the most common contamination issues on sensitive production lines, particularly in semiconductor, MedTech and optical assembly.
Why standard motor tools fail cleanroom requirements
Standard brushed motors generate carbon particles as the brushes wear against the commutator. Where the limit is 3,520 particles ≥0.5 µm per cubic metre, even a single brushed screwdriver can push a workstation out of compliance. The particles are invisible to the naked eye, but they reduce wafer yield, scratch optical surfaces and contaminate medical assemblies. ISO 14644-1 defines the particle limits for each cleanroom class, so you can match the tool to the spec.
Brushless screwdrivers for ISO Class 5 cleanroom work
We supply Mountz brushless electric screwdrivers specifically designed for cleanroom use. Because they have no carbon brushes, particle generation from the motor itself is effectively eliminated. Torque accuracy still meets ISO 6789 requirements, so you do not have to trade accuracy for cleanliness.
What to check before you deploy a screwdriver
- Motor type — brushless only, with sealed or low-shed bearings
- Housing material — low-outgassing plastics or anodised aluminium, wipe-down friendly
- Cable and connectors — ISO-compatible materials, no PVC where possible
- Documented particle generation data at the target cleanroom class
- Compatibility with ESD-safe workstations where the line is also ESD-controlled
Which model suits your line?
The right model depends on fastener size, torque range and whether your ISO Class 5 cleanroom is static-sensitive. For manual preset work, see our Mountz FG-CR cleanroom torque screwdrivers (including the compact FG Mini cleanroom preset screwdriver); for static-sensitive benches, the ESD screwdrivers. Our engineers can walk you through options and also recommend compatible cleanroom furniture and gloves for a fully compliant workstation.
