The first impression
Packaging and labeling
ℹ️ Here we take a closer look at packaging. Sustainability is becoming an increasingly important factor. In addition, adequate protection of the product must of course also be ensured.
| Criterion | Remark | Score achieved* |
|---|---|---|
| Product protection | Shipping and product carton are sturdy, product sufficiently protected | 100 points |
| Sustainability Packaging | No unnecessary packaging waste was used, items were packed compactly | 100 points |
| Packaging convenience | Packaging was easy to open even without tools | 100 points |
| Total | 100 points |
*The maximum score is 100 points
The premium stainless steel decking screws from INNONEXXT® were delivered in a compact and sturdy shipping box. The shipping box was easy to open, even without tools. As the shipping box was slightly oversized, the empty space was filled with recycled paper. Inside the box were the decking screws in their product packaging. This meant that the decking screws were very well protected during transportation.
The product packaging is a resealable cardboard box in a simple green design. Again, no tools are required to open it. The box is appropriately sized for the decking screws and is filled almost to the brim with screws. This saves space during transportation. Like the product box, the decking screws are undamaged and in very good condition. In addition to the screws, the product box also contains a small plastic bag in which the appropriate bit for the screws is shrink-wrapped. The bag lies on top of the screws and protects the bit from scratches caused by the sharp-edged screws. Above all, however, the bag ensures that the bit can be found quickly and easily in the pile of almost identically colored screws.
After unpacking
Package contents and instructions
ℹ️ Most people’s first impression after unpacking is immediately memorable. Are the contents of the package complete and does the manufacturer make it as easy as possible for me to use the product straight away?
| Criterion | Remark | Score achieved* |
|---|---|---|
| Package contents & scope | 200 decking screws with matching bit | 100 points |
| Instructions for use | Not available, but also not necessary | 100 points |
| Contact information | Can be found on the product packaging. Unfortunately no telephone number or e-mail address | 70 points |
| Total | 90 points |
*The maximum score is 100 points
The set contains 200 decking screws. The matching bit is also included so that the screws can be screwed in using a standard screwdriver or cordless screwdriver with bit holder. A screwdriver is not included in the scope of delivery.
Assembly instructions are also not included, but in our opinion are not necessary for the screws. The technical data with screw dimensions and material are printed on the product packaging.
The contact details can also be found on the product packaging. These include the company name, the company address and a website. Unfortunately, contact details are only available on the website. We would also have liked to see a telephone number and an e-mail address.

*The maximum score is 100 points
The decking screws are supplied in the size 5.0 x 50 mm. The first number indicates the diameter including thread, the second number the length from the tip to the end of the head. A measurement confirms the manufacturer’s specifications. According to the manufacturer, the screws are made of stainless steel and are anti-friction coated. Stainless steel is resistant to corrosion and weathering. The screw is therefore also suitable for prolonged outdoor use. The coating is characterized by a slightly greasy surface. The color of the screw is matt-sibern, the mass of one screw is 3.9 g.
The screw consists of five segments: it starts with a tip that extends over a length of 10 mm until the screw reaches its full diameter. The tip is threaded from the start and also has a cutting notch to prevent cracking and splitting. The tip is seamlessly followed by a 20 mm long threaded section. The thread pitch is 2 mm, the internal diameter 3 mm. This is followed by the third part, the 10 mm long end mill. This has several threads, a significantly larger thread pitch and a reduced outer diameter of 4 mm. This serves to shorten the screw-in time. This is followed by another 4 mm long shank with a diameter of 3.5 mm. The end of the screw is formed by the conically widening head with a length of 6 mm. This increases the diameter at the end of the screw to 6 mm. The top of the head is slightly rounded and has a drive profile for T25 bits.
Like the screws, the matching T25 bit is matt silver. It has a length of 25 mm. With its hexagonal profile, the bit fits into standard bit holders.
Overall, both the screws and the bit holder make a very good quality impression. They are sturdy and very well made. The good quality and weather-resistant material of the screws indicate a long service life.
This is what our practical test showed
Does the manufacturer keep its advertising promises?
ℹ️ Our practical test is the most relevant and therefore the most important. Here, the product has to undergo a wide range of criteria and tests. We check the functions and product promises of the test article.
| Criterion | Remark | Score achieved* |
|---|---|---|
| Fitting the screw | Easy to screw in thanks to thread up to the tip and sliding coating. Unfortunately, the screw cannot be magnetized. | 90 points |
| Use of the bit | Robust and stable bit, fits well in screw and bit holder, does not slip out thanks to magnetizability | 100 points |
| Quality of the screw connection | High connection force of the screw, rounded screw head reduces risk of injury | 100 points |
| Total | 97 points |
*The maximum score is 100 points
A commercially available cordless screwdriver is used for the practical test. Although in principle it is also possible to screw in the screw with a screwdriver, it is much easier with a cordless screwdriver. Thanks to the thread starting at the tip of the screw, the screw grips firmly in the wood after just a few turns and starts to turn into the wood. The screws can be screwed in easily and without great effort. The anti-friction coating helps here. With soft wood, as in our case, no pre-drilling is necessary.
The conical countersunk head allows it to be fully countersunk into the wood so that nothing protrudes. However, a small disadvantage of the screws is that they cannot be magnetized and therefore do not adhere to the bit. This makes it easier for the screws to come loose from the bit and possibly slip between already installed decking boards.
The T25 bit supplied fits perfectly into the screws and into the bit holder of our cordless screwdriver. In contrast to Phillips screws, the bit does not tend to slip out of the screw by itself. This means that once the screw has been gripped, no axial force needs to be exerted on the screw during screwing, which makes screwing in very convenient. As the bit can be magnetized, it remains in the bit holder even if it is held upside down – as is the case when screwing in. After screwing in, the bit can be easily removed from the bit holder.
After screwing them in, we found that the screws actually grip very well and create a stable connection between the decking boards. It is not possible to get stuck on the screws, which are completely countersunk into the wood. This is particularly important as a terrace should also be able to be walked on barefoot . If a screw is not fully countersunk into the wood, the rounded shape of the screw head helps to reduce the risk of injury. As the screws are made of weather-resistant stainless steel , they should retain their strength and appearance even when left outdoors for long periods of time.
In summary, it can be said that the optimization of the decking screw in trials actually offers demonstrable advantages. Installation is simple and convenient. Even after installation, the screws impress with their rounded head and high-quality material. Accordingly, the screw and bit made a very good impression in the practical test.
Price/performance ratio
and ratings from consumers
ℹ️ Finally, we look at how the product compares to the competition. Can it keep up with the competition in terms of price and quality? Would we generally recommend buying it? We also examine consumer ratings and check whether the critical and positive reviews are actually justified.
| Criterion | Remark | Score achieved* |
|---|---|---|
| Price / performance ratio | Very good quality in the mid-price segment | 80 points |
| Rating cut | 4.7 out of 5.0 on Amazon | 85 points |
| Total | 83 points |
*The maximum score is 100 points
On the Amazon platform, consumers have given the product an average rating of 4.7 stars. One common criticism is that the screws are made of material that is too soft and can break off. Many customers like the high quality of the screws and the ease of installation. In our practical test, we were able to confirm that the quality of the screws was good and that they were easy to screw in. No screws tore off in our test.
Prices of up to €63.90 are charged on the Internet for equivalent products. However, most products are in the €43 range. Very inexpensive products are available from as little as €15.90. The decking screws from INNONEXXT® are currently in the mid-price segment with a price of €31.49. The price ratio is reasonable for the quality and scope of services you get.
