Application
Combination wrenches like the Open/Box End Combination Wrench, No. 40081313 from STAHLWILLE combine the benefits of box wrenches and open-end wrenches. One side is a closed loop for hexagonal or square nuts, and the other end is an open U-shape. Used most often for difficult nuts, a combination wrench's closed end loosens the nut so the open end can be used to unscrew it quickly.
Origin
The first combination wrench dates to the 1800s. The idea was to create a versatile wrench with an open-end and boxed-end combination to remove bolts and nuts from a wide variety of applications.
Features and benefits
The thumb groove along the wrench handle eliminates material without stress and concentrates it where needed. Similar to the principle of an H-beam in construction, extreme loadbearing capacity and maximum flexural strength are achieved with a lower weight.
The Anti-Slip-Drive profile enables high-force transmission without damaging the fasteners. While the force acts on the flats of the screws, the corners are left free and are not rounded off. Thanks to the forged double hex, they are tougher than any fastener.
Selling points
When force is applied to a wrench, the greatest force acts on the area between the jaw and the shank, which is why STAHLWILLE wrenches are reinforced at this point. The special design makes the load zones more resilient, which reduces the risk of breakage to a minimum.
Extremely thin-walled rings facilitate work in confined spaces. In addition, the rings are higher than standard nuts, which prevents the wrench from seizing on the nut.
Manufacturing/engineering specifications
- Made in Germany using a special manufacturing process that allows for thin-walled rings that are perfect for screwing in hard-to-reach places
- Extremely resilient and durable, stronger than any screw
- High-quality, non-slip surface texture for safe working even with oily hands
- Robust chrome-alloy steel gives the combination wrench high durability and wear resistance
