What is the self-drilling screw Head of the Flat? Full explanation for self-drilling screw head
self-drilling screw Head of FlatAlso known as the common name in Israel. self-drilling screw Head of Flat (Self-Drilring Rivet Head Screw), is self-drilling screw to steel, where a prominent head (sush or elephant head) is equipped with a flat and low head, similar to the head of an item – combining the edge of a drilling knife. This structure allows Burg to suffocate the raw material and penetrate it in one continuous operation, just like a regular self-drilling screw, but with a head suitable for the connections required by a low profile and aesthetic conversion.
Series series RS of Adit Ltd It is a classic flat head, which comes in two material versions: RSZ - made of steel (type C1035) with a cold glory coating, suitable for connecting steel to steel and steel to aluminum; andRS A2 - made of 304/A2 stainless steel, suitable only for aluminum profiles (no risk for a global corrosion). Both models are encrypted until a profile thickness of 4.4 mm, without the need for early drilling.
When is the self-drilling screw a flat head used? self-drilling screw flat head is suitable for wherever a prominent head interferes: doors and windows are drawn, aluminum rails, profile frames, aluminum cladding and steel, metal furniture, and products requiring a clean and undressed finish that does not capture and does not sway with pleasant elements.
Advantages of self-drilling screw flat head RS from Adit
- A flat and low head: Not noticeable, does not take in the fabrics, rubbers or swarms – a perfect solution for aluminum profiles and rolling doors.
- Technical data is happy: The values of the plaque/Nrd and the gira/Vrd are accurate for each diameter and profile thickness, also to connect steel and to aluminium connection.
- direct fastening technology for steel: The self-drilling screw and Brig in one action – without a pre-emptive nibb and no further accessories.
- Two materials for each application: RSZ from the colluton to the steel connections, RS A2 is converted into non-corrosion aluminum connections.
- A variety of locomotives and guests: ST3.5/ ST4.2/ ST4.8, guided from 9 to 38 mm – a complete solution to any constructive specification.
Technical data is happy - load tables for self-drilling screw flat head
The following data constitute the basis for the safe engineering planning of connection through self-drilling screw Head of Flat. . . All the values in tables are in KN to a single screw. Note: Typical failure load (Nrk/Vrk) is not a soft load. Use the prepared load (Nrd/Vrd) or the recommended load (Nrec/Vrec) in actual planning, and make sure the profile itself suffers for a severance.

* The infusion in the giraffe does not occur in the resolution of the profile (steel or aluminum). The plan must be checked to examine the profile’s suffering for the final rapport. Using the screw steel (RSZ) to connect aluminum may cause a cosusia - aluminium connection is recommended to prefer the hyrosta version. RS A2.
The aesthetic aspect of a flat head – not only strength, also shows clean.
One of the most prominent Advantages of self-drilling screw Head of Flat It is the aesthetic dimension. The head of the screw at low, round and abundant (Flat Bevelled Head) at an altitude of just 1.2-1.5 mm, so after installation it appears to be partially “sufficient” and hidden within the line of the profile – without an ugly bump or a prominent shadow across the metal.
- Clean and hidden finish: The flat head does not blur the berg point, which is particularly important in visible clarifies, aluminum frames and glass doors.
- Aesthetic replacement for the item: self-drilling screw a flat head can be used as a replacement for the item in a variety of applications, with the extra advantage it can be decoded and reconnected.
- There is no interruption to the parts of the trail: The low head prevents the swaying in the doors and sliding windows, tracks, and other drag mechanisms.
- The ring swipe under the head: Owrote the drilling chips that are created in the process, so the screw is sitting completely and adjacent to the profile – further improvement in the final tyrant.

installation guide is fast – self-drilling screw Head of flat
- Mark the drilling point: A slight smack for the signaling position will prevent a "removing" of the drilling knife in the beginning of the round.
- He screwed with amphlet: The recommended drilling speed is 1800-2500 rpm to steel at ST3.5/ST4.8, 1000-1800 rpm in ST4.2; in the nigger (RS A2) is lower – 1000-1500 rpm in ST3.5/ST4.8 and 600-1000 rpm in ST4.2.
- The screw in the profile: Hold the screw in 90 degrees for a uniform pressure material. The quaint rang makes the breaking of the drill knife and a damaged connection.
- Stop with the flat head: Since the RS is flat and low, it is easy to miss the stop point and continue to be more likely to be excluded. Stop as the head is uniformly attached before the profile and before it is over-whelming in the material.

Common Questions and Answers (FAQ) – self-drilling screw Head of Flat and self-drilling screw Head
What is the difference between self-drilling screw and a flat head to self-drilling screw with a niche head?
self-drilling screw Head of Flat (Like RS) is designed with a low, flat and platter head that fits wherever there is no place for a prominent head – for example aluminum profiles, doors and windows are being pulled. Burg with a niche head (such as ABE) requires more space but allows the hook in the key and the compression is higher. The choice between them depends mainly on the constraints of the place and the final look requirement.
What is the difference between RSZ and RS A2?
RSZ Made of steel (C1035) with a cold gluton coating, and are suitable for connecting steel to steel and steel to aluminum. RS A2 Made of stainless 304/A2 and is only intended to connect aluminum profiles – it prevents a glucousia that can be formed when a normal steel screw is installed over time in aluminum, especially in an outdoor or humid environment.
How do you choose the self-drilling screw diameter as the right flat head?
The choice depends on the thickness of the profile that plan to penetrate and load required: ST3.5 is suitable for a minute steel of up to 2.25 mm, ST4.2 to the thickness of up to 3.2 mm, and ST4.8 (the most common in the RS series) is coded up to 4.4 mm thick profile. The larger the diameter is, the greater the load of the flucation and the recommended gem rise.
self-drilling screw is a flat head suitable for doors and sliding windows?
Yes, it’s one of its leading applications. The low and low head of Burg RS does not interfere with the movement of parts of the snares, does not take up attima and on the tracks, so is the accepted choice in the aluminum industry for the frameworks, rails and sliding mechanisms.
Is self-drilling screw a flat head? Is there a stainless version?
The RSZ version comes with a cold platoon that is suitable for protected environments. When self-drilling screw installs a flat head in aluminum, or in an outdoor and coast environment, it is recommended to move to the gram RS A2 Mansorta 304 – which is not vaccinated and does not produce a glory corrosion against aluminum.
Can I use a flat head to connect aluminum?
Yes, but the right material must be selected: the use of the screw steel (RSZ) to connect the exposed aluminum to moisture may cause a global corrosion that will hit the connection and aluminum over time. For long-term aluminum connection it is recommended to use the hyrosta version. RS A2That does not cause this phenomenon.
Why is the self-drilling screw drilling knife broken or not broken?
In most cases this happens due to incorrect installation: the exclusion at an curve angle and not injected to the profile, high- or low-level speed from the recommended in the RPM table, or attempt to drill large-silometer- thickness from the selected screw diameter. Using cheap bugs with steel soft is another common cause of the failure of the drilling.
What is the difference between Nrd and the tax?
Typical failure load (Nrk) is the screw or profile courses in destructive laboratory tests. Do not plan project by the failure load! Engineers divide the failure load in a standard safety booster to reach the Nrd (safe prepared load) or Nrec (the recommended load for service). Adit provides engineers with all the necessary data to this calculation.
Can the self-drilling screw break up a flat head and re-engine it in the same hole?
It is possible to break down the screw, but it is not recommended to return and kill it exactly to the same hole. The return screw is plucked at the Burg and a guy in a profile and may damage the suffering of the fire. In such cases, it is recommended to move to a larger screw diameter or place the new screw at a slight distance from the old hole.
