ESD screwdrivers are static-dissipative fastening tools for electronics assembly, PCB repair and any workstation where stray charge could kill a component. Because the operator’s hand and the tool body are both part of the discharge path, an ordinary screwdriver on an ESD bench quietly defeats the mats and wrist straps around it.
What makes a screwdriver ESD-safe
Mountz ESD screwdrivers carry a dissipative coating holding surface resistance in the 10⁵–10⁸ Ω range, tested to IEC 61340-5-1 and ANSI/ESD STM11.13, so the line stays compliant with ANSI/ESD S20.20. Therefore the tool drains charge at a controlled rate instead of either insulating it or dumping it.

The range
Phil Industries supplies Mountz ESD-safe preset torque screwdrivers in Singapore from 3 ozf.in to 125 lbf.in, in standard and compact FG Mini formats with colour-coded labels. Each one seals shut and resists tampering, so the set value survives the shift. In addition, they belong on an ESD-protected bench alongside wrist straps, mats and ionisers rather than on their own.
The two Mountz ESD screwdriver families
| Model family | Torque bands | Drive | Best for |
|---|---|---|---|
| FG ESD preset torque screwdrivers | Six bands from 2 cN·m to 14.1 N·m (FG-25z ESD to FG-125i ESD) | 1/4″ female hex | PCB assembly, connector and housing fasteners, rework benches |
| FG Mini ESD preset torque screwdrivers | Two bands, 2 – 17.7 cN·m and 14.1 – 35.3 cN·m | 1/4″ female hex | Micro fasteners on camera modules, sensors, medical electronics |
Both families are cam-over preset tools: the clutch releases at the set torque, so an operator cannot over-tighten, and the colour-coded label (blue, red, green or gold) tells the line which preset a driver holds. Buyers also search for these as ESD safe screwdrivers, anti-static screwdrivers or static-dissipative torque drivers; they are the same tool. For adjustable or non-ESD versions, see the Mountz torque screwdrivers overview, and for ISO Class 5 work see the cleanroom torque screwdrivers.
Completing the ESD-protected workstation
An ESD screwdriver only works when the operator and bench are grounded too. Therefore pair it with an ESD wrist strap, a dissipative ESD rubber mat and the rest of our ESD safe tools range, and follow the checklist in our ESD grounded workstation guide. If you are unsure whether a standard screwdriver is acceptable inside an EPA, our FAQ on standard screwdrivers in an ESD protected area answers it.
Frequently asked questions
What ESD standards do Mountz ESD screwdrivers meet?
A surface resistance of 10⁵–10⁸ Ω, which IEC 61340-5-1 and ANSI/ESD STM11.13 verify. As a result, they support ANSI/ESD S20.20 compliant assembly lines.
What torque range is available?
From 3 ozf.in (FG-25z ESD) to 25–125 lbf.in (FG-125i ESD), so micro through medium torque is covered.
Can I use them on an ESD-protected workbench?
Yes. Mountz designs them for ESD-safe assembly, so they sit naturally alongside mats, wrist straps and ionisers.
Are ESD screwdrivers supplied calibrated?
Yes. We can supply new Mountz tools preset and calibrated on request. In addition, as a trusted Mountz distributor serving Singapore manufacturers since 2009, we stock genuine spare parts.
