Common Questions and Answers (FAQ) – self-drilling screw stainless and methel

What is self-drilling screw B-Tel and why is it better than a normal flora?

self-drilling screw in Me-Tel Martine two metals: body and head of the SS304/SS316 to resistance Perfect beforecorrosion, and a carbon steel tanker is covered with C1035 for high straws. The full stainless burger It is not hard enough to drill steel directly; the beta-metametametametametabolical combination allows direct drilling without any other tool.

What is the difference between BIE and BAUTO – which self-drilling screw-Tel to choose?

BIE Designed for carbon and cold connections in profiles up to 6 mm thickness, available in three The diameters (ST4.8, ST5.5, ST6.3) and the lights 25–80 mm. BAUTO Specifically intended For heavy IPN drilling, with a capacity of drilling up to 12 mm in the ST5.5 diameter and 40–100 mm wide. A rule of thumb: for the carbon and slight profiles – BIE; for the rows and heavy profiles – BAUTO.

Is self-drilling screw stainless BIE suitable for marine environment?

version of BIE A4 with a body AISI 316 (Al-Hild) andcoating Atlantis C3-H Specifically designed for aggressive environments including sea, chemical industry and high humidity. The standard BIE version with AISI 304 is suitable for general outdoors; the coastline and marine environment - you must choose BIE A4.

What is the right drilling speed for the BIE screw in steel compared to stainless?

In steel: ST4.8 – 1800–2500 rpm; ST5.5 and ST6.3 – 1000–1800 rpm.
In Norse: ST4.8 – 1000–1500pm; ST5.5 and ST6.3 – 600–1000 rpm.
Too fast in nitrosta will cause overheating and the knife’s erosion; these limits must be met. Not to exceed the maximum time of drilling.

What is the difference between a typical failure load (N)rk(N) The poor (NN)rd)?

Typical failure load (N)rk() It is the value of the connection with destructive laboratory tests. The load will be ready. (N)rd() is the value divided in safety centers according to devices, and is used for actual planning. No plans are not allowed to be planned. project construption directly according to failure loaders – NNF should be used.rd(Only.)

What is Atlantis C3-H and why is it important in self-drilling screw-Metel?

The Atlantis C3-H coating is a unique protective coating that swayes the drilling knife of the humiliary screw. Since the knife is made of carbon steel (which is not stained), it may be swayed in a humid environment. The coating Protecting the knife and maintaining the drilling capacity even under aggressive conditions, ensuring that the screw will arrive on the site. Ready for use.

Why is it essential to use the screw stainless steel at Metel and not in the steel Gallon in a aluminum connection?

When steel gluton comes in contact with aluminum in the presence of moisture, it is created. The global corrosion This causes accelerated liquidation of the two metals. Use ofself-drilling screw at Dalal stainlessa BIE It completely eliminates this risk and ensures a stable connection over the years. This is why the tables include Separate values for connecting with steel and aluminum.

What is the maximum profile thickness for drilling with BIE – can you drill 6 mm steel?

Yes. yes. BIE's ST5.5 diameter is capable of drilling a steel profile in thickness up to 5.25 mm, and the ST6.3 diameter comes from Up to 6.0 mm. Reporting in thicker profiles (up to 12 mm) should be transferred to theBAUTO intended for this.

Full technical data – the load tables for steel and aluminium profiles, drilling speeds, dimensions and catalogue numbers for both BIE and BIE A4 – is given in the technical datasheet above.

What is a Bi-Metal Self-Drilling Screw?

A bi-metal screw joins two metals in one fastener: a stainless-steel body for corrosion resistance, and a hardened carbon-steel drill point welded to it so the screw can drill straight into steel – something plain stainless is too soft to do reliably. The ADIT BIE drills and fastens in a single pass, then resists corrosion for the long term, making it the right choice for steel fixings in coastal, humid and aggressive environments.

The advantage: the drilling power of a carbon-steel self-drilling screw with the corrosion resistance of stainless – one fastener that both cuts into steel and survives outdoors by the sea.

BIE is offered in two stainless grades: BIE (SS304-C1035) for coastal and humid conditions, and BIE A4 (SS316-C1035) for marine and aggressive environments. Both carry an Atlantis C3-H coating, have a hexagonal washer head, and drive into steel and aluminium profiles up to 6.5 mm thick. They are supplied in three diameters – ST 4.8, 5.5 and 6.3 – in lengths from 25 to 80 mm.

Applications

Coastal & marine steelwork

Steel fixings by the sea, where a plain zinc screw would rust – BIE A4 (SS316) for the most aggressive, salt-laden sites.

Façades & cladding

Exterior cladding, rainscreens and architectural metalwork that must stay corrosion-free.

Roofing & wall sheeting

Profiled sheet and panels fixed to steel purlins in humid or exposed locations.

Stainless-to-steel connections

Joining stainless or steel elements where the fastener itself must resist corrosion.

Insulated & sandwich panels

Panel fixings in humid conditions; combine with an EPDM washer for a weather-tight seal.

Pools, food & wet areas

Indoor environments with chlorides or constant moisture where stainless is required.

Installation Guide

1 · Mark & position

Mark the entry point with a light tap, and hold the screw perpendicular (90°) to the profile.

2 · Set the speed

Use a high-speed screwdriver – roughly 1000–2500 rpm in steel depending on the diameter (lower for stainless base). Excessive speed can burn the drill point.

3 · Drill through

Let the carbon-steel drill point cut fully through before the thread engages; keep the total thickness within the drill-point length.

4 · Seat & finish

Stop as the screw seats against the profile – do not overtighten. With an EPDM washer, compress until the seal just spreads.

BIE – bi-metal self-drilling screw

Frequently Asked Questions

What does “bi-metal” mean?

The screw is made of two metals: a stainless-steel body for corrosion resistance, and a hardened carbon-steel drill point welded to it. The carbon point drills through steel, and the stainless body keeps the whole fastener corrosion-resistant – a combination plain stainless cannot achieve, because stainless is too soft to drill hard steel.

What is the difference between BIE and BIE A4?

Both are bi-metal. BIE uses an SS304 stainless body, suited to coastal and humid environments. BIE A4 uses an SS316 stainless body, which resists chlorides better and is intended for marine and aggressive, salt-laden environments.

How thick a profile can BIE drill?

BIE drives into steel and aluminium profiles up to 6.5 mm thick in a single pass, in the ST 4.8, 5.5 and 6.3 diameters. The datasheet gives the load values for each base material and size.

When should I use BIE instead of ABE?

Use ABE (zinc-plated carbon steel) for standard indoor and dry work. Use BIE when the fixing is exposed to a corrosive, coastal, humid or marine environment and must resist rust for the long term, while still drilling into steel.

What is the difference between Nrk and Nrd?

Nrk is the characteristic failure load – the load at which the connection physically fails in destructive testing. Nrd is the design load the engineer uses: Nrk divided by the safety factors required by the relevant standard. Always design with Nrd. The datasheet lists Nrk, Nrd and recommended (Nrec) values for steel and aluminium.
