self-drilling screw flat head BCP – self-drilling screw to connect the steel and aluminum profile
self-drilling screw flat head BCP He is self-drilling screw (Self-Drilling Screw) is uniquely flatheaded with Philip Key (Ph), designed for connections requiring a low head that is not noticeable above the surface. The screw combines a drilling knife at the end of which allows it to suffocate the profile and screw in one action – without drilling early.
self-drilling screw flat head BCP Especially suitable for connecting steel and aluminum profiles with a thickness of up to 4.4 mm (steel) or up to 2.0 mm (Nasta A2), and serves hallucination doors, windows, embedded locks and applications in which a thin and aesthetic connection is required.
When is the self-drilling screw head in the BCP? Typical applications include: the metal frame train, aluminum profile connection, installation of coatings and girls, metal furniture production, and wherever a prominent head can cause a side or get caught in pleasant parts.
Advantages of self-drilling screw flat head BCP - not all self-drilling screw is the same.
- A particularly flat head: A low head and a platter in a hymika radius and is not seen in pleasant parts – ideal for sliding doors, windows and locks.
- Technical data is happy: Values of fun and precision gem for each profile thickness, which enable safe and documented engineering planning.
- The direct fastening technology: The self-drilling screw and Brig in one action – without a pre-emptive nigger, without additional accessories.
- Available in a variety of versions: steel with a cold gallon (BCPZ, BCPB, BCPN, BCPZ BL) and the A2 aerospaces for moisture and aggressive environments (BCP A2).
- Support and engineering responsibility: Adit engineers are available to help select the right model, calculate load and stand in technical specifications.

The following data constitute the basis for safe structural planning. All the values in tables are in KN to a single screw. Note: The infusion in the box does not occur in the resolution itself (steel or aluminum). The planner should check the profile’s suffering for a rash to determine the final ring.

Important note for BCP A2 (Nastta): The screw is designed for use with only aluminum and is not intended to drill steel – the drilling knife will be burned due to the irrigation of the nobility of the hyrosta. For the steel drilling in a corrosion environment, the BIE beta-metametallic models should be used.
installation guide Fast – self-drilling screw Head of BCP
- Mark the drilling point: A slight suffocation with a precision marnch will prevent the smoothing of the drill knife of the snail. self-drilling screw Head of Flat At the beginning of the round.
- Prepare the right screw: Use the Impression. The speed is recommended: in steel 1000–1800 rpm, in the nigger 600–1000 rpm. An exception to the speed causes the burning of the drill knife.
- The screw in the profile: Hold the screw in 90 degrees to material and uniform pressure. The quaint rang makes the breaking of the drill knife and a damaged connection.
- Stop with the screwhead: When the head The frozen screw Stick to the profile - stop. Over-experience will hurt the needle and weaken the connection.

Common Questions and Answers (FAQ) – self-drilling screw Head of Flat BCP
What is the difference between self-drilling screw and a regular self-drilling screw head?
self-drilling screw flat head BCP A low-profile head (Extra-Flat Head, angle 65°) that is partially entered into the profile and is not noticeable above the surface. This is against the classic screw ABE that has a high-sused head with a savior. The BCP is designed for connections requiring a minimum in the latte – such as the sliding doors, window frames and profiles where pleasant parts are moving.
What is the difference between BCPZ, BCPB, BCPN and BCPZ BL?
All these models are self-drilling screw Head of Flat From steel C1035, only distinguished by the outer coating: BCPZ – a cold (end), suitable for internal use; BCPB – full white coating (RAL 9010), white cladding and white frames; BCPN – black coating, black profiles and black components; BCPZ BL – a normal, but only white-looking body with white, white-like head.
When should I use BCP A2 (Nast) and not BCP steel?
When you connect aluminium profile around moisture, water or other – mandatory Use of -BCP A2 (S304/A2). The use of the regular screw steel within aluminium exposed to moisture causes a global corrosion that will destroy the connection and profile. The BCP A2 is made of stainless steel A2 and comes with a psycheduling coating, and ensures inaction with the aluminum.
Can BCP A2 be used for a report on steel?
No. self-drilling screw, BCP A2 It is only intended for use with aluminum. Experience to drill steel with a screw stainless steel will cause the burning of the drilling knife – since the A2 is not difficult enough to penetrate steel. The steel report on the condition of corrosion should be used in the Adit beta-metallic samples.
What is the maximum profile thickness that self-drilling screw flat head BCP can drill?
The steel (BCPZ/BCPB/BCPN) can be analyzed in a steel profile with a thickness of up to 4.4 mm. The BCP A2 (Noma) model is limited to the thickness of up to 2.0 mm (aluminium). An exception of the maximum thickness will result in breaking the drilling knife and failing installation.
Why is the screw knife broken?
The common causes of breaking a knife inself-drilling screw Head of FlatThe junction at the angle (not 90 degrees), too high-level speed, drilling in a thick profile from the motors permitted to the sample, or using BCP A2 on steel (for example). Using cheap bars from unhappy sources – including the soft knife – is causing another common failure.
What is the difference between a failed load (Nrk) and a recommended load?
Typical failure load (Nrk) is the figure in which the screw fails in laboratory tests. Nrd is the figure that engineers use it for safe engineering (after dividing safety). The recommended load (Nrec) is even more conservative for use in most construction applications. You cannot plan by loading the failure! Adit provides professionals with all the necessary data to calculate correctly.
What happens if I tighten the self-drilling screw flat head BCP too strong?
The overcrowded of self-drilling screw Head of Flat It may cause the “excellent” thread in the thin profile, to damage the diaspora, and to the distortion of the profile itself. The maximum hydraulic hydraulic to ST 4.2 is 4.7 Nm. It is recommended to use the embarrass with a predefined mode of momentum.
