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.
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.
