What is self-drilling screw stainlesshead ABR A2? Full explanation.
self-drilling screw Nesssssssssssta HeadAlso known as the name. self-drilling screw Nesssssssssssta Head (Stainless Self-Drilling Screw, Dome Head), is a engineering connection that combines a drilling knife, and is the main round-and-a-bulated kit (Pan Head/ Dome Head) – all made of steel to the snorkel. This structure allows Burg to suffocate the raw material and penetrate it in one continuous operation, without the need for a nibbling or drilling early of a hole.
ABR A2 He is a model. self-drilling screw Nesssssssssssta Head of Adit, made 304 stainless steel / A2 (SS304) With a psycheduling, and designed and happy for technology direct fastening for aluminum profiles The thickness between 2 and 4 mm. The low-poch head provides a broad presidential area across the connected surface, dividing the load and preventing a sunset into the material – and all this without damaging the resistance high corrosion characteristic of the rosoasta.
When is the self-drilling screw stainless ABR A2? self-drilling screw stainless ABR A2 It is mainly suitable for connecting aluminum profiles in the environments where resistance is high corrosion: aluminum cladding out, frames and aluminum windows, pragility, outdoors, coastline areas, chemical industrial structures, and any other application in which a regular cold platoon does not provide sufficient long-term protection.
Please note: ABR A2 is happy and is taught to connect Only aluminum profiles. . . The screw is not intended and is not approved for a direct drill in steel profiles. steel applications should be used in the sample ABR The usual (karon), which includes happy load tables for connecting steel. Full details of the questions below the article.
Advantages of self-drilling screw stainlessaBR A2 – Not all self-drilling screw stainless is the same.
- Technical data is happy: Values of fun and precision gem for each diameter and thickness of aluminium profile (allowed for sure engineering planning).
- 304/A2 stainless substance with psycheduling: resistance Cosie is significantly higher than the regular self-drilling screw in a cold glory – suitable for outdoor environments, coastline and chemical industry.
- Head of aesthetic and functional enforcement: The low and espous screw head (Pan Head) provides a maximum presidential area and a representative look, and is suitable for visible connections in aluminum cladding and frames.
- direct fastening technology for aluminum: The self-drilling screw and Brig in one action – without a pre-emptive nigger, without accessories and without “death time” on the ground.
- A variety of options: 3 diameters (ST3.5, ST4.2, ST4.8), snorts from 9.5 to 50 mm, PH2 – a solution full of most common aluminum carriers.
- Support and responsibility: Designed for contractors and planners requiring back engineering, load tables and compliance with strict building regulations.
Technical data is happy – self-drilling screw stainlessa ABR A2 – ABR A2 – A link to aluminium profile
The following data constitute the basis for the design of safe structures of aluminum connection with the help of self-drilling screw stainlessa. All the values in the table are in KN to a single screw. Note: The values listed below include a typical failure load (Nrk/Vrk), a valid load (Nrd/Vrd) and a recommended load for service (Nrec/Vrec). For engineering planning, appropriate safety promotions should be applied. The planner must also make sure the profile itself suffers for a tear.

installation guide Fast – self-drilling screw stainless ABR A2 (Aluminum)
- Mark the drilling point: A slight suffocation with a precision marque will prevent the break of the screw knife at the beginning of the round.
- Prepare the right screw: Use the screw quickly around the (rpm) suitable for the screw diameter according to the above table. Unlike carbon steel, stainless steel is sensitive to friction – too fast can cause perception (Galling) and the breaking of the drilling knife.
- The screw in the profile: Hold the screw in 90 degrees to material and constant pressure, without interim constipation. The exclusion in an angle or non-continuous pressure causes increased friction and a weak and damaged connection.
- Stop with the hand of the head of the dome: When the head of the screw’s dome is attached to the aluminum surface – stop in a controlled manner. The barga persists after the clutch raises friction and endangers both the screw and the burger in aluminum.

Common Questions and Answers (FAQ) – self-drilling screw stainlesshead ABR A2
What is the difference between self-drilling screw stainless and self-drilling screw?
Burgbourg The stain of stainless Made of the steel A2/304) with a psycheduling coating, so much more resistant to corrosion, ⁇ and damage to cleaning and veins. Ordinary self-drilling screw (such as the standard ABR) may be carbon steel with a cold glories coating, which corresponds to protected but significantly weakened interior environments outside, near the sea, or in a chemical environment. When there is a doubt, Nessssta is the long-term safe choice.
self-drilling screw stainless ABR A2 is suitable for a direct report on the steel profile?
No. self-drilling screw stainlessa Head of ABR A2 is approved and ranked, according to the official Adit load tables, connection and direct fastening. Only for aluminum profiles 2-4 mm thick. Do not carry out a self-driving with the steel profile – both because of the drilling knife metrics adapted to aluminum, and due to the lack of happy load data for steel for this model. steel applications should be used in the sample ABR The usual (karon), which includes happy load tables to connect steel with 2-5 mm thickness.
What is the difference between stainless A2 (304) and the A4 (316) in self-drilling screw?
Nirsta A2 (304), from which ABR A2 is made, offers resistance very good corrosion for most foreign environments, aluminum cladding and skulls. stainless A4 (316) contains a melybden supplement and provides even higher resistance for all downloads, and is specifically designed for aggressive environments such as the desalination facilities, sea pools directly, or a harsh chemical industry. Most aluminum applications in construction and outdoors, A2 is the most recommended and economic solution.
Is self-drilling screw stainless and snoring during the burglar? How to avoid it?
Yes, this is a familiar phenomenon in the stainless veins called Galling – a high friction between two similar metallics that causes the screw caught in the wire and sometimes its capital. To prevent this: you should be at low RPM speed from recommended to a regular steel, exercise uniform pressure and quarry, avoid new stops and beginnings in the same barge, and stop immediately with the attaching of the head of the dome to the surface.
Why should the self-drilling screw frivolous burger be slower (RPM) and normal steel burg?
stainless steel is more easily heated than carbon steel during friction, and the heat generated at a high rate increases the risk of perception (Galling) and the accumulation of the drilling knife. ABR A2 is therefore designed for work at controlled speeds: 1000-1500 rpm for the ST3.5 and ST4.8 diameter, and 600-1000 rpm for the ST4.2 diameter.
Is there any ulcousia when self-drilling screw stains are stained with aluminium profile?
There is a mildly ulched potential between stainless steel and aluminum, since the two metals are a certain distance in the galvanical series. However, the risk is much lower than the acute glycologic corrosion caused by the use of a normal carbon steel in aluminum. ABR A2’s fertilization coating further reduces the risk, so it is the standard and acceptable solution in the industry to connect aluminum profiles in an outdoor and coastal environment.
How do you choose the correct diameter and length of the self-drilling screw stainless ABR A2?
The diameter was selected by the thickness of all aluminum layers that must be penetrated: ST3.5 is suitable for thickness including 0.70.25 mm, ST4.2 to 1.75-3.00 thickness from VAT, and 4.8 to thickness 1.75-4.40 mm. The length was selected so that enough wires are stored in the subject profile – the maximum-floor aluminum thickness table above to match the length of the screw to the thickness of the layers.
What is the difference between Nrd and a typical failure load (Nrk) in self-drilling screw stainless?
Typical failure load (Nrk) is the screw or profile courses in destructive laboratory tests. The efficiency (Nrd) is the value after a distribution in a safety booster, and the Nrec is the recommended load in long-term service. Do not plan project by the failure load! Adit provides engineers with all the necessary data to carry out the correct calculation.
Can you break self-drilling screw stainless ABR A2 and re-engine it into the same hole?
The screw can be broken and the connection is released, but Not recommended New screws to the same hole itself. The first screw gently swayes the ingeniousness created in aluminum, and the repeated screw can significantly damage the absorption. In such cases it is best to move to a larger screw diameter or place the new screw at a slight distance from the old hole.
self-drilling screw stainless steel ABR A2 magnetic?
A2 304/A2 stainless steel is usually not magnetic or magnetic in a very weak way, unlike conventional carbon steel bars that respond to the magnet. This feature is sometimes used for quick check-out in the area of the identity of the Burg material, but is not a replacement for checking a qualified MacT and Engineering consultancy.
