Wera 05074731001 Kraftform ESD 7441 Hexagon Torque Screwdriver, 1/4" Head, 1.2-3.0 Nm Variable Torque Adjustment Range

I'm a former US Navy helicopter mechanic, but these days, I do long-distance bicycle touring. This screwdriver is one of two Wera torque screwdrivers I use to maintain and repair my and my wife's long-distance touring bicycles. This type of bicycling demands a bike that is exceptionally reliable. That means, not only must the bike be robust, it must also be properly set up with all bolts and screws properly torqued... not too tight, not too loose, not stripped out, and not crushing their associated components. This screwdriver lets me set the smalest screws & bolts on my bikes to within specification and that lets me ride with more confidence in remote areas because I know that such fasteners are less likely to come loose, less likely to be stripped, and less likely to crush the delicate components they're holding fast. I love my Wera screwdrivers, and I'll own a set for as long as I live.

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.

Very accurate. I tested this against 2 other torque wrenches and it is very accurate. It’s easy to adjust and numbers are legible. Works perfectly. Definitely worth the money.

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.

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.

I do a lot of PC/server building and maintenance and having a torque screwdriver can prove handy when vendors provide a specific torque spec. This is an good option for a common range of torque values at a very reasonable price. I can't speak to the accuracy of the torque applied, but it's certainly better than "hand tight."

This works as expected.

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.
