Features 5
- FINE TORQUE CONTROL IN 0.05 NM STEPS: Dial in an exact setting from 0.3 to 1.2 Nm by hand, so small precision fasteners get consistent clamping force every time.
- RAPIDAPTOR QUICK-RELEASE CHUCK: Swap 1/4in hex bits in seconds without extra tools, cutting downtime on repetitive assembly, rework, and bench work.
- ESD-SAFE FOR SENSITIVE COMPONENTS: Surface resistance of 10^9 Ohm helps protect static-sensitive parts during PCB assembly and electronics repair.
- KRAFTFORM HANDLE FOR ALL-DAY USE: Hard and soft grip zones reduce hand fatigue on long runs of repetitive, low-torque screwdriving.
- CLEAR SETTING, AUDIBLE CONFIRMATION: An easy-to-read scale and a noticeable signal when preset torque is reached, plus a hexagonal body that resists rolling off the bench.
Description
Small fasteners are the ones that get ruined by guesswork — too little torque and the joint works loose, too much and you crack the housing or strip the thread. The Wera 7440 ESD lets you set anywhere from 0.3 to 1.2 Nm by hand, in 0.05 Nm steps, with ±6% accuracy to DIN EN ISO 6789. Built for ESD-controlled environments, its surface resistance of ≤10⁹ Ohm helps protect static- sensitive electronics during assembly and rework — while the Rapidaptor quick- release chuck lets you change 1/4in hex bits in seconds, without stopping to grab a separate tool. The multi-component Kraftform handle balances hard and soft zones for grip and speed without hand fatigue, and the hexagonal body keeps the driver from rolling off a workbench. Suitable for bits per DIN ISO 1173-C 6.3 and E 6.3. Made in the Czech Republic by Wera, a brand built around ergonomic, precision hand tools for technicians who work the same fastener hundreds of times a day.

Broke after a just a few light-duty uses on lowest torque setting. Cracked center bushing.
Size: 2.5-11.5"/lbs Variable Torque Adjustment ...
I love WERA and own dozens of their products. Never once had an issue. But literally after just a handful of few light-duty uses, I went to use this and noticed no resistance. Looked a little closer, and the entire center ring was loose and cracked. Unbelievable for such a good brand and expensive product. Time to see if WERA honors their "lifetime" warranty. If they do, I'll update my post. UPDATE: WERA Honors Their Lifetime Warranty! I am updating my review to reflect the relatively hassle-free warranty service received from WERA. Aside from the fact WERA seems to make it impossible to find out HOW to request warranty service, I managed to locate the process. If you run into this issue, send an email to orders at weratools dot com with a copy of your Amazon receipt, photos and description of the issue. I had to mail my defective unit to NY and within a couple weeks, a brand new replacement was sent back provided at no charge.

Works great to tighten tonearm/cartridge screws.
Size: 0.3-1.2 Nm Variable Torque Adjustment Range
I bought this to torque my turntable cartridge to the headshell of tonearm. The torque is 0.4 Nm. As I'll rarely use this tool, it's nice that you can remove the stress on the spring like you can with other adjustable torque tools. This tool will sit around for months if not years. But, when I need it to recheck or adjust my cartridge alignment, I can be sure I haven't added any memory to the spring. Setting the tool is simple and intuitive. While I think this is an extravagance for most. But if you've spend a lot of money on cartridge, incorrect torque can change the azimuth of the stylus. This is something to be avoided. Great tool.

I use this thing to torq down incerts. All the other machines in the shop have stripped fasteners. Mine do not. I mention this to my boss every week; he doesn't care but I do.

Wera ESD 7446 Torque Driver
Size: 11.0-29.0"/lbs Variable Torque Adjustment...
Specs were a little vague on this item before I ordered it. I was looking for a torque driver to go 50-60 in. lbs but this only goes to 25 in lbs I believe. Still works great to torque the lighter stuff like mounting rifle scopes and such. It's east to use, just push the front of the handle in, hold and turn handle to desired in. lb. and start torqueing away. Clicks when you reach you desired torque, no more broken screws! German quality with a great warranty, comes with factory calibration report as well. Does exactly what it should for it's intended purpose.

Easy to use and effective
Size: 11.0-29.0"/lbs Variable Torque Adjustment...
The screwdriver includes a calibrated measurements. Easy to use and it makes an audible snap and stops prior to over torquing. You may want to invest in long set of bits since the size of the head is large and may make it tricky to access tight spots.

I think the Capri is better than this. The feeling of rotaly slip and stripping screw aer less different than Capri. But it's better than CDI torque driver.
