Torque Screwdrivers — Wiha
A torque screwdriver tightens small fasteners to a set value, which stops both under-tightening (loose fittings) and over-tightening (stripped threads and cracked housings). They suit electronics, instruments, light machinery and any assembly where the specification calls for a precise low torque. AIMS Industrial stocks the Wiha torque screwdriver range: adjustable Torquevario-S, preset Torquefix and Easytorque, ESD and VDE insulated models, variable torque sets, bit holders and an adjusting tool. Torque values are in Nm, and our Metric Bolt Torque Chart is a useful reference for matching a value to a fastener.
Quick Reference — What's in This Range
| Type | What It Is | Torque Range |
|---|---|---|
| Torquevario-S | Adjustable, with the torque set within the range of the model | 0.1-0.6, 0.4-1.0, 0.5-2.0, 0.8-5.0 and 2.0-7.0 Nm |
| Torquevario-S ESD | Adjustable ESD version for electronics assembly | 0.04-0.46 and 0.4-1.0 Nm |
| Variable torque ESD screwdriver | Adjustable ESD screwdriver | 0.8-5.0 Nm |
| Variable torque VDE insulated | Adjustable insulated screwdriver for work near live parts | 0.6-2.0 Nm |
| Torquefix and Torquefix T | Preset to one fixed value, so every fastener gets the same torque. The T version has a T-handle. | Fixed values, from 0.15 Nm; check the variants |
| Easytorque | Preset torque screwdriver | 0.5 Nm |
| Sets | Variable torque sets of 11 and 13 pieces, and a Slimtorque starter kit | Slimtorque kit 1.0-5.0 Nm |
| Accessories | 1/4″ hex bit holders (standard and ESD) and a torque screwdriver adjusting tool | — |
Adjustable or Preset?
An adjustable screwdriver such as the Torquevario-S covers a range of values with one tool, so it suits varied work and maintenance. A preset screwdriver such as the Torquefix is set to one value and used for that value only, which suits repeat jobs where every fastener needs the same torque and nobody should be changing the setting.
Choosing a Range
- Fine electronic and instrument fasteners — the lowest ranges, such as the Torquevario-S ESD at 0.04-0.46 Nm or the Torquevario-S at 0.1-0.6 Nm.
- Small mechanical fasteners and general assembly — the 0.5-2.0 and 0.8-5.0 Nm Torquevario-S models.
- Upper end of the screwdriver range — the 2.0-7.0 Nm Torquevario-S. Above about 7 Nm, a torque wrench is the right tool.
- Electronics assembly — the ESD models.
- Work near live parts — the VDE insulated model. Check the marking on the tool and follow your site electrical safety procedures.
Choose a model whose range puts your target value in the middle of its scale, rather than at either end.
Care and Calibration
Wind an adjustable torque screwdriver back to its lowest setting before storing it. Leaving it at a high setting keeps the spring under load and shortens its accuracy life. Store it in its case, away from impact, and do not use it as a general screwdriver or for loosening. Have it checked on a regular schedule and after any drop. Many quality systems require annual checks. Contact us if you need calibration options.

People Also Ask — Torque Screwdrivers
Q: What is a torque screwdriver?
A torque screwdriver applies a controlled, measured torque to a fastener. An adjustable model clicks or releases at the set value, and a preset model does the same at its fixed value, which prevents over-tightening. They are used where the specification calls for a precise low torque, such as electronics, instruments, light machinery and terminal blocks.
Q: What torque range do torque screwdrivers cover?
Our Wiha range runs from 0.04 Nm to 7 Nm across the Torquevario-S and Torquevario-S ESD models, with preset Torquefix and Easytorque screwdrivers at fixed values. For higher torque, a torque wrench is the right tool.
Q: What's the difference between an adjustable and a preset torque screwdriver?
An adjustable screwdriver lets you set the value within a range, so one tool covers varied work. A preset screwdriver is fixed at one value, which suits repeat jobs where every fastener needs the same torque.
Q: What's the difference between a torque screwdriver and a torque wrench?
A torque screwdriver handles low torque and uses a screwdriver-style handle with 1/4″ hex bits. A torque wrench handles higher torque and drives sockets or insert tools. Where the ranges overlap, a torque screwdriver gives a finer feel on small fasteners.
Q: How do I store a torque screwdriver?
Wind the setting back to the minimum before storing, because leaving it at a high setting keeps the internal spring loaded and shortens its accuracy life. Store it in its case in a clean, dry place, away from impact and direct heat.
