About Us


STAHLWILLE tools are built to tolerances and specifications most tool companies are unwilling or unable to meet.   All of the products made by STAHLWILLE are manufactured in Germany under the most stringent quality control conditions.

STAHLWILLE approaches tool making differently than most.  Instead of making tools that appeal to the masses and expecting professional technicians to use them, STAHLWILLE makes tools engineered for the professional technician knowing every tool user, at every level, will appreciate them.

It has been said that only a rich man can afford to buy cheap tools.  Those of us who appreciate our tools understand this all too well.  Initial cost is one thing.  When you total the cost of ownership over time, STAHLWILLE tools are clearly a more cost effective choice.  Once you calculate the cost of replacing worn tools, fixing and replacing damaged fasteners, the cost of downtime and general frustration, you realize buying cheap tools is very expensive.

If cheap tools were designed for safety, ergonomics, durability, and accuracy, they would no longer be cheap.  I think most people agree, “You get what you pay for.”  That is very true with tools.

Organizations such as OSHA (Occupational Safety and Health Administration) and NIOSH (National Institute for Occupational Safety and Health) monitor workers in many industries for what they call musculoskeletal disorders linked to hand tool use.  They know anytime you use a tool repeatedly for hours you can become sore.  They also recognize the quality of a tool and the amount of soreness felt are often related.  The results of using cheaply made tools are pain and suffering, lost workdays, reduced productivity and other economic costs.  At first glance, it is often difficult to see which tools are well made.  You must consider ergonomics, physics, geometry, etc.  STAHLWILLE considers those and more.  STAHLWILLE tools are designed to be an extension of your hand.

Safety is another huge concern when making your tool selection.  We often relate safety only to power tools.  However, using cheaply made hand tools can be just as dangerous.  We assume our screwdriver blade won’t snap or our wrench won’t slip.  With cheap tools, you never know.  When you use cheap tools you are far more likely to injure yourself or someone around you.  Technicians using STAHLWILLE tools should find them to be safe and easy to use with a high degree of reliability, quality, and consistency from one size to the next.  Innovations like the Manoskop 730 FIX demonstrate STAHLWILLE’s commitment to safety.  Read more about the “FIX” here.

Although health issues remain the primary concern, productivity is important as well.  When you choose cheap tools you reduce productivity and efficiency.  The cost of fixing a rounded bolt head or the cost of downtime while you replace a broken tool (or part) can be critical in a business.  Selecting a toolmaker that considers safety and productivity are important.

So you might ask, “What makes one tool better than another?”  That would be a good question.  Some have argued the answer is simple.  Does the manufacturer focus primarily on the cost of making the tool or do they focus primarily on the user and the purpose of the tool?  STAHLWILLE tools are designed and built with the user and the practical application in mind.

There are several factors that determine the overall quality of a tool.   The top 3 might be:

  1. Materials – there is a wide diversity of material available globally. Obviously, some is cheaper than others.
  2. Manufacturing Processes – Things like “FORGED and FINISHED” or “CAST” have to be considered. How are the tools actually made?  Does the manufacturer outsource production or is it in-house?
  3. Design and Engineering – Not only do you need to know who is designing the tool but you need to know if they are involved in the manufacturing process as well. Did the manufacturer engineer the tool with safety, comfort, and productivity in mind?  Be sure the same people who design the tools monitor every step of the manufacturing process to be sure nothing is lost due to cost cuts, shortcuts, or just a lack of understanding as to what the tool is supposed to do.  When manufacturing is outsourced, that close monitoring and understanding can be lost.

STAHLWILLE uses only high-grade materials.  When you engineer torque wrenches that will stand up to abuse and when you make general purpose tools with tight dimensional accuracy and non-flaking chrome, only the best materials can be used.  STAHLWILLE uses specially selected steel that allows wrenches to be thinner, lighter and stronger.  Proprietary manufacturing techniques result in tools that maintain their dimensional accuracy throughout their life.

See 2 examples of STAHLWILLE quality at STAHLWILLE University:



STAHLWILLE believes FORGED and FINISHED in Germany should be a guarantee of quality.  When many companies are outsourcing manufacturing to faraway countries, STAHLWILLE is committed to keeping everything in Germany.  Some claim outsourcing does not impact quality.  They argue that quality materials can be purchased anywhere and all countries have capable people to do the work. Those points may be true.  However, material and labor are not the only factors that influence quality.  STAHLWILLE believes in order to maintain the highest quality possible, all departments need to work together from design through finished product.  Everyone tied to a product line needs to be engaged throughout each process. Outsourcing creates a gap in the control process.  When a third-party facility in another country is contracted to make a product, it is difficult to maintain quality standards.   When questions are raised, the answer often involves cost cutting, not quality improvement.  In many cases, once a process is moved offshore, the designers and engineers are removed from the manufacturing process.  Taken directly from the STAHLWILLE website, “…STAHLWILLE is committed to Germany as a manufacturing location.  We believe that it is only here that we can guarantee adherence to our ambitious quality target: every single product has to exceed the requirements laid down in the standards.”

STAHLWILLE has been recognized for its innovation.  The jury of the TOP 100 competition in Germany recognized STAHLWILLE as one of the most innovative small and medium businesses in Germany for 2017.  The jury was “particularly impressed by the way this tradition-based enterprise has integrated the philosophy of innovation in its organization and the day-to-day work and lives of its staff. (top100.de)”  Even after more than 150 years in business, STAHLWILLE is still looking for better ways to produce the best tools possible for its customers.

Although not a physical part of the tool, STAHLWILLE believes tradition plays a large role in the quality story.  Since STAHLWILLE was founded in 1862, the WILLE family has insisted on quality.  STAHLWILLE was the first company in the hand tool industry to receive DIN EN ISO 9001certification in 1989.  Through generations of WILLE family management and global pressure to outsource manufacturing, production has always remained in Germany.

Having control from start to finish can be more expensive but STAHLWILLE believes the end result is worth it.  When you spend so much time and effort designing a tool to be the best, you don’t want to lose that effort thousands of miles away in a foreign production plant.  STAHLWILLE is proud to offer safe, comfortable (ergonomically correct), efficient hand and torque tools that look great, feel good in your hand and do what they are supposed to do, every time, for a lifetime.


Intelligent torquing technology is used daily in the aerospace, automotive, energy and industrial industries.   As one of the world’s most respected tool manufacturers, STAHLWILLE combines traditional, “tried and true” German tool making practices, state-of-the-art production techniques and digital technologies to meet the needs of today’s technicians.

The value of a tool can be determined by how long it remains at work without failure or down time.  Measured in this regard, we believe STAHLWILLE torque wrenches are the best value available to a professional technician.

No Spring – A huge advantage over other torque wrench designs. No spring means accuracy across the entire scale, no loss of % of scale at either end. More usable range equals fewer torque wrenches needed. A user can go from 7 ft.lbs. to 725 ft. lbs. @ 3 torque wrenches. (18 in.lbs. to 3600 in. lbs. @ 3 torque wrenches.)

No need to zero the wrench – No spring means no loss of accuracy. Leave the wrench set at a fixed value for weeks or
months and maintain critical accuracy.

Interchangeable heads – Why buy three torque wrenches when you can buy one wrench and a set of inserts. Choose from ratcheting heads, fixed square drive, quick release, crow-ring, Crowfoot, ring inserts or make your own with the available weld on the adaptor.

Accurate over time – STAHLWILLE torque wrenches are built to the ISO 6789 requirement of calibration every one year or 5,000 activations. Delivered to the customer at +/-3% with a traceable certificate (730N) (+/-1% for digital, +/-4% for 730 series) the torque wrenches carry a 3-year accuracy warranty. Each mechanism is rated to hundreds of thousands of activations thus assuring long life and accuracy. Holding this % accuracy over time is where this mechanism excels.

Accurate Settings – The new 730N has a setting scale designed for maximum accuracy. Choose a major value in the big window then references the small window near the dial to lock in the value in as small as .5 increments.

Use as a Breaker Bar? – A torque wrench is often the longest lever a tech has on hand. It is a simple fact that any other torque wrench used as a breaker bar is effectively ruined to say nothing of inaccurate. STAHLWILLE mechanical torque wrenches are built to be used as a breaker bar with no damage to the wrench, mechanism or accuracy. Reassuring in Aerospace, Aviation, Automotive, Military or Industrial applications.

Calibration & Operation – No need to disassemble the wrench to calibrate it. Simply use a 2 mm hex key and two set screws on the wrench. No need for soaking. Simply follow the standard ISO 6789 procedure and once calibrated the wrench is back in service. Less downtime = more productivity.



No spring – So there is no need to zero the wrench. Ever.

Full range of the wrench can be used accurately – No % loss at top or bottom.

Use as a breaker bar – with NO damage.

Accurate to read and set.

Comfortable – (Ergonomic)

Long, long life – Mechanical interface rated to 240,000 + activations.

Interchangeable heads – Buy one torque wrench and then purchase the heads you need. This is incredibly cost effective. Purchase one wrench and then 1/4″, 3/8″ and 1/2″ ratchet insert heads. Add a couple of crow ring inserts and a crowfoot or two. Imagine a torque wrench that wears in, not out.

With a recommended calibration cycle of one year or 5,000 activations.


The Technology behind the STAHLWILLE 721, 730 & 730N series Torque Wrench.

No need to Zero

✓ The beam remains at rest until torque is applied. Nothing is under load.

✓ Maintains accuracy throughout the calibration cycle.

✓ A full visible range of the scale can be used. No loss of % at top or bottom of the indicated range.


The closer to the block the cam moves the higher the torque value. (The more difficult for the trigger to slip past the block.)


It’s a firing mechanism from a machine gun. Rated to hundreds of thousands of clicks. (activations) STAHLWILLE Torque Wrenches meet the ISO 6789 requirements for 12 months or 5,000 activation calibration cycles. STAHLWILLE Torque Wrenches have held a one-year calibration cycle with the USAF for over 3 1/2 years. (33K-1-100-1)

Breaker Bar

STAHLWILLE torque wrenches are built to be used as Breaker Bars. The Insert head beam just moves off the Mechanism! Insert head Beam Torque Goes this way. “Breaker Bar” Goes this way. Mechanism Using other torque wrenches as a Breaker Bar damages them. (Also ruins their accuracy).

Over Torque Protection

After the small triangle passes the block it cannot move any further. It hits the wall of the wrench. No damage. Triangle Torque Goes this way. Over torque seriously damages other torque wrenches. (Also ruins their accuracy).

Drop “Protection”

Once the ramp angle is calibrated it is “fixed.” Dropping has little effect on accuracy due to the design of the ramp mechanism. 50/50 chance that other torque wrenches are seriously out of cal and need repair or replacement if they are dropped. (Also ruins their accuracy).


No disassembly required to calibrate or adjust. A 2 mm hex key is all that is necessary to adjust the wrench.

Common Parts
From 20 in.lb. to 725 ft.lb. with just five torque wrenches. Common Parts All five torque wrenches share the same components except for the measurement scale and labels.

Interchangeable Heads

Cost effective. No need to buy extra torque wrenches. Simply add heads as needed.

Reduce the number of wrenches to calibrate, track, and maintain. The Same center point on most inserts.

Perfect for LEAN implementations, build kits to specific processes.
