If you have been contacted by an account with ‘HAZET’ in its name and told that you have won our raffle, it is important to carry out a few verification steps to ensure that it is a genuine HAZET account:

1. Verifying the account: First, check whether it is an official HAZET account. You can find a list of all officially active HAZET social media accounts here (link to other FAQs)
2. Matching the raffle account: Bear in mind that winners are only contacted via the account through which the raffle was run. Make sure the message comes from the same account you used to enter the raffle.
3. Do not provide sensitive data: We will never ask you for your bank details, login details or similar sensitive information. If the message asks for such details, it is most likely a scam.
4. Reporting fake accounts: If you realise that you have been contacted by a fake account, please report it immediately and let us know. Your help is crucial in preventing fraud and ensuring safety within the community.

We place great importance on ensuring that our raffles are conducted fairly and securely. Your safety and trust are important to us, and we thank you for your attention and caution when taking part in our social media activities.

1. Find a specialist dealer: Use the dealer search on our website to find an authorised HAZET specialist dealer near you or in your country. Simply visit the HAZET dealer search link to discover local specialist dealers.
2. ‘Buy Now’ button: With the relaunch of our website, we have introduced a convenient way to purchase HAZET products. The ‘Buy Now’ button on the product pages connects you directly to dealers who stock the product you’re looking for. You can choose between local specialist dealers or online dealers.

The models differ primarily in terms of size, number of drawers, capacity and worktop material (plastic or stainless steel). Larger models such as the 179NXL, 179NXXL or 179NXXLD offer higher capacities and more storage space.

However, there are also service trolleys or the forerunner of all tool trolleys – the tool trolley "Assistent 166N"

Here you will find a summary table of all current tool trolleys and work benches, showing their technical features

Yes. Please enquire with HAZET: standard RAL colours are available even for small quantities.

Depending on the model, the capacity per drawer ranges from approx. 30 to 50 kilograms. Heavy-duty versions offer a correspondingly higher capacity.

You’ll find all the details in this summary table

Yes, thanks to the drawer locking mechanism, only one drawer can be opened at a time, which minimises the risk of it tipping over.

Yes, the work surfaces feature built-in interfaces for accessories such as laptop holders or add-on modules. There is also a wide range of accessories available for organisation and expansion

In this table, we’ll show you the suitable accessories … and if anything ever breaks, the suitable spare parts too

The tool trolley "Assistent" features:

• double-walled construction
• edge protection with a damping system
• robust powder coating and stainless steel components
  

Things can get rather hectic in the rough and tumble of workshop life. One momentless slip where you brush against a customer’s vehicle with the tool trolley, and the paintwork is already damaged. Fortunately, the high-quality HAZET tool trolleys feature a flexible impact protection system that minimises the risk of damage.

The system consists of a central locking mechanism with a cylinder lock. The mechanism locks the drawers securely with a force of up to 1,000 N, ensuring that your valuable tools are protected against theft.

Yes, of course! Because we place great importance on sustainability! That’s why, for example, we offer a wide range of spare parts for purchase through our spare parts shop … often for over 10 years. In this table, we show you which spare parts we have available for your tool trolley.

Alternatively, you can also select your spare parts using our exploded views

Whether you’ve lost your key or it’s snapped off in the lock – our closing cylinders have a serial number that allows you to quickly reorder your key. Simply contact our service centre. And if nothing else works, you can always replace the complete locking system

We have already reliably addressed one of the most common reasons for complaints about our tool trolleys: on the newer models, all the locks are now positioned on the sides rather than at the front. This means that the wrench can no longer break off in the event of a collision. As an extra safety measure, many models of our tool trolleys are fitted with folding keys. This provides additional protection!

Our tool trolleys are always fitted with a push handle. The mobile work benches are supplied without a push handle. The worktop on the work benches is always made of multiplex (wood), whilst with the tool trolleys you can choose between a sturdy plastic worktop or a stainless steel one.

Our tool trolleys are designed for everyday use in workshops, industry and service sectors, and offer a mobile, organised system for storing tools.

All our mechanical torque wrenches are calibrated for clockwise tightening (right-hand thread).

However, you can use our torque wrenches with square drive (9x12 or 14x18 mm) to operate a left-hand thread. Simply turn the insert tool 180° and insert it into the tool holder.

Our recommendation for the test/calibration interval is based on the DIN EN ISO 6789:2017 standard for torque wrenches, which recommends recalibration after one year, after 5000 loads or after every overload. The inspection intervals must be shortened in case of increased quality and safety requirements or intensive use. The calibration interval is specified by the user, as he is responsible and knows the use of the test specimen.

A torque wrench is a measuring instrument that should not be used for purposes other than its intended use. Other tools, e.g. the HAZET 6396 or 6397 tool holders, or a compressed air impact wrench or cordless impact wrench, are better suited for loosening fastenings.

HAZET tests, calibrates and certifies torques, including those from other brands. However, repairs are not available. We would be happy to provide you with an attractive offer to purchase a technically comparable HAZET torque wrench.

The performance of an impact wrench operated on compressed air is influenced by various parameters. A key factor is the compressed-air system to which the impact wrench is connected. As compressed-air systems vary from user to user, it is not possible to specify reliable torque values that apply to all such systems.

For professional workshop use, you will need a large workshop compressor with a tank capacity of at least 200 litres

Smaller compressors are usually unable to supply the impact wrench with a sufficient supply of air over the long term. This means you have to keep taking breaks whilst working so that the compressor can refill the air tank.

The working pressure is always measured directly on the device whilst air is flowing through it. Why not have a look at our pressure loss calculator too?

The air connection nipples we supply usually have sealant applied to the thread; furthermore, most air connection nipples have tapered threads. It is therefore usually not possible to screw them all the way down to the bottom of the thread. If the thread alone does not provide a sufficient seal, you can help by using a little Teflon tape, for example.

Air quality is specified in ISO 8573-1. According to this standard, the air should be as dry as possible (no condensation), oiled (for corrosion protection and lubrication) and free from foreign particles. After the compressor, your system should therefore at least include a water separator, a fine filter and a lubricator.

In accordance with our internal business and corporate identity guidelines, we are required not to publish any image that does not feature at least the HAZET logo and, preferably, our HAZET number. For some products, technical constraints make it impossible to apply visible and permanent labelling. Consequently, the appearance of the product on delivery may differ from the catalogue or online images.
However, as a brand manufacturer, we are frequently confronted with counterfeit products. Counterfeit products do not meet our strict quality standards and can, e.g., endanger your safety in the event of a failure due to overloading. We are therefore grateful for any information you can provide. If you are unsure whether you have purchased a genuine HAZET tool or a counterfeit, please feel free to contact us at any time. The best way to do this is to send a photograph of the item and the dealer’s link to [email protected].

The video borescopes are designed for inspections of confined spaces and therefore focus within 10 to 60 mm (4812-11/5FS) or 10 to 100 mm (4812-23/5AF). Within this distance, the image should be razor sharp.

The sockets for manual operation are chrome-plated and have a different (heat) treatment than sockets for power screwdriver use.
The use of impact wrenches can cause damage to the sockets. The material cannot absorb the impacts so well. Above all, however, the surface can flake off. Chrome splinters can be very sharp and cause injuries.

Yes, HAZET pins are available from the HAZET Fan Shop and can be ordered online.
