Wera 7003C – 1/2″ Torque Wrench

Today we have the Wera 7003C, 1/2 “drive torque wrench. This wrench is in fact made by Norbar out of Banbury England in the UK. This is not simply a sticker label rebrand, this design was made particularly for Wera and also has a number of differentiating aesthetic attributes such as the manage shade as well as the laser-etched Wera name as well as logo design on the shaft.

Requirements as well as Features

Initially allow’s have a look at the listing in Wera’s magazine to obtain the fundamental specifications. This specific design has a torque series of 40 to 200 newton-meters or about 30 to 150 foot extra pounds.

Making use of some study it resembles this is a variation of Norbar’s 200 collection Automotive Professional Torque Wrenches. Particularly I had the ability to tighten it to component number 10314. Normally the Norbar brochure is mosting likely to provide is a little bit even more details on the attributes of the torque wrench.

The automobile collection torque wrenches they use are developed with take care of as well as lens products that stands up to all chemicals typical in vehicle and also aeronautics market. The Norbar directory additionally shows it is a 72-tooth cog and also weights 1kg, which is fairly light for a 1/2″ drive torque wrench of this dimension.

Product packaging as well as Contents

This torque wrench can be found in among those 2 component tubes that you typically see utilized for points like end mills as well as huge drill little bits. I possibly would have favored a committed instance yet this will certainly be sufficient since the situation is multiple-use unlike a few other sorts of product packaging around. I believe the situation was a sacrifice they made to maintain the price down.

The system features a calibration certification where they examine the system at the minimum, middle and also optimum torque analyses. In this specific situation the calibration was within 1% although this torque wrench is ranked at 4% precision. So it resembles I prevailed as well as obtained a system that is carried out well over specification.

Turning around Mechanism

This is a relatively easy to fix torque wrench, yet I think it is just adjusted to enter the tightening up instructions, which is shown by a huge arrowhead on the shaft of the system. The instructions changing device is distinct because it moves throughout the leading the head.

I do not remember ever before seeing a cog with this design system as they are all normally a tiny bar or a wheel that you transform. Relocating the slide discloses an arrowhead that suggests instructions that the cog will certainly transform for that setting.

Changing the Set Torque Value

To readjust the collection torque, the handle at the end of the wrench is transformed a quarter kip down the counter-clockwise instructions to the opened placement.

This enables the manage itself to turn which will certainly revolve the moving range. The wanted torque is after that associated the red line on the home window. As soon as established, after that the handle at the end is reversed a quarter transform clockwise to secure the placement.

Moving Dual Scale

I did discover that there appears to be a little reaction on the torque established device. Someplace like one college graduation or around 2 newton meters. I do not believe it is actually a massive bargain, however I would certainly have really felt much better if I could not relocate the gliding range after it is secured. Norbar simply lately update this certain version with a various change system so I’m unsure if they transformed it because of this or otherwise.


This is a click-style torque wrench that will certainly trigger a springtime packed device to displace when the collection torque is gotten to. This kind of torque wrench that additionally calls for a solitary hand to be on the deal with. There are kinds of torque wrenches available that are setting independent yet this specific design is not one of them. When you get to the collection torque placement, the device will certainly displace as well as create a distinct click noise to show the wanted torque has actually been gotten to.

I utilized this torque wrench just recently when doing some added hex essential screening as well as it functioned incredibly well. I was really shocked at exactly how refined the click device was.

Evaluating the Torque Wrench

We’ll have a look at some blew up representations later on to attempt as well as figure out why this is. I’m utilized to those kind of torque wrenches that will in fact displace rather a substantial quantity simply under the head. Nonetheless, this set just has a really little variation if there is any type of whatsoever which I such as. The click is likewise not incredibly loud, yet the good news is you can still really feel the resonance with the take care of.

Obviously with any type of torque wrench, after you are done utilizing it you need to constantly establish it back to the minimal worth, which is normally 20% of the optimum.

Celtic Cross Markings

There was one uncommon noting on this torque wrench that had me doing a double-take. If you look carefully on the takes care of there is plainly a Celtic cross which actually captured me by shock.

Celtic Cross on Handle

I’m certain the majority of people would not assume much of this as it is an old Christian icon, however a great deal of other individuals additionally understand that this specific icon is currently identified with white preeminence teams throughout the globe.

Celtic Cross Example– Used by Neo-Nazi Groups

It is identified as a hate icon by the Anti-Defamation League that keeps in mind

” … is just one of one of the most typically made use of white supremacist signs.”– ADL

Nonetheless, the ADL additionally keeps in mind that as a result of the commonness of this specific sign, in the lack of any type of context it is not always a hate sign.

” … the frustrating use this variation of the Celtic Cross is non-extremist as well as, in the lack of various other hate signs, does not represent white superiority or bigotry.”– ADL

Offered current occasions I would not be stunned if they wind up eliminating this or changing it with a few other icon.

Element Examination

Back to the device, I do not believe I’m mosting likely to tear right into this to check out the internal parts due to the fact that it would certainly screw up the calibration. Thankfully, Norbar gives a took off representation of this device that must provide us some added understanding right into its building and construction.

The very first point you will certainly discover is the amount of line products this setting up has. I had no suggestion that a torque wrench might be this complicated. I have actually uncoupled torque wrenches previously, such as the Gedore Dremometer and also they were not virtually as detailed as this version.

Below is my analysis of the taken off layout on just how this in fact functions. When you transform the handle at the end of the wrench to the secured setting a springtime presses on a scratched collar that involves with a fixed part of the manage. When the handle is relied on the opened placement, it presses on the drive sleeve tabs which creates the springtime to press. This consequently presses the scratched collar right into the fixed equipment which involves with the inside tailored published range.

Norbar’s initial license reveals this system in a little far better style than the taken off illustration does.

Things that makes this torque wrench special is that transforming the manage to change the wrench does not really relocate the hold up the shaft like it does on several various other versions. I’m not exactly sure if Norbar is the just one that makes a torque wrench with this attribute, however I have not seen one in the past.

The system that creates the clicks is a fair bit additionally right into the torque wrench. This is why there is really little variation when the collection torque quantity is gotten to and also permits the click noise to be stifled.

I’m unsure of every one of the products utilized, yet it shows up a great deal of the tailored components are constructed out of glass-infused nylon. This should not truly be a trouble considering that the only time the equipments remain in usage is when you are readjusting the collection torque worth.

Snap-On Acquires Norbar

If you adhere to Tool sector information you will certainly recognize that Norbar was just recently gotten by Snap-On for 72M USD a number of months back. Taking into consideration that Wera is a rival of Snap-on, the future of a Wera-branded Norbar torque wrench is not recognized currently. Current meetings with Norbar agents have actually shown that procurement does not alter anything as well as it is service customarily. Snap-on likewise has numerous various other firms that for concentrated on the torque market so I’m not specifically certain of their intents with this acquisition. We’ll simply need to wait as well as see.

Final thought

In conclusion, the 7003 is a terrific mid-level torque wrench that does the job without damaging the financial institution. Things I such as most regarding it are the low-impact click device, the really simple to check out twin range as well as the comfy deal with. The only genuine downsides I can discover is the little of reaction on the change device as well as the truth it does not included a much better situation. These are small problems that I can deal with.
