Warning for Biltema's decking screw

[Mikaelzii]

On the topic of Biltema's screws and the burden of proof from Råd & Rön

Since she couldn't specify which screw she used, she has likely used the wrong one, just as Biltema claimed.

I've made the mistake of screwing a 40m2 deck with Biltema's brown C4-rated "deck screw" myself. It's made of very hard and brittle steel. This caused all the screws to snap as soon as the deck started to move a bit. This screw is pure junk and Biltema's labeling as "deck screw" creates a huge headache for Svenssons who aren't knowledgeable about steel composition. I had to pry and unscrew all of them and replace them with stainless steel. This process took longer than building the deck itself.
I will never buy a single item from Biltema again, ever.

I myself made the mistake of using Biltema's brown c4 rated "deck screw" on a 40m2 deck. It's made from very hard and brittle steel. This caused every screw to snap as soon as the deck started to move a little. This screw is pure rubbish and Biltema's labeling it as "deck screw" creates enormous headaches for those not familiar with steel composition. I had to remove and unscrew every single screw and replace them with stainless steel. This process took longer than building the deck itself.
I will never buy anything from Biltema again, ever

Pretty obvious in my eyes that one should choose a stainless steel deck screw.
You don't exactly have the deck indoors.

Biltema's, and many others, are not stainless steel, why they are bought/sold is beyond me.
No, I'm not a screw salesperson or carpenter.

On the other hand, Essve has also delivered substandard decking screws:

yep, just because something is expensive doesn't mean it's good.

I've encountered junk when buying DeWalt, flooring from Golvabia, Bosch to name a few.

And I mean that just because Biltema sells it, it doesn't have to be crap

But I usually say "you never get more than you pay for."

They had quality problems with hydrogen embrittlement

Feel free to google it.

If you want to do a good job, you don't use hardened screws but stainless steel of good quality.
Essve stainless has never had problems.

A2 within the country and A4 in coastal areas.
I would never think of using Biltema's hardened decking screws for a deck.

I have built 2 large patios with Biltema's stainless decking screws. Haven't noticed any issues at all. One is 5 years old, the other 3.

Biltema sells a lot of good things, but you need to have a bit of sense. Hand tools can often be bought at Biltema and also motor oil, but screws may not be their strong suit. It's usually the case that you get what you pay for.

have you found more info indicating this? From what I see from the clip, I rather assumed that she fell on the burden of proof before ARN where it would reasonably be difficult to show a defect in the product without investing in getting inspections done, possibly analyses on the screw, etc. I don't see that she failed because they doubted the product didn't come from Biltema.

Quoting again "she has probably used the wrong screw" wrong length maybe? Or a completely different screw for indoor use even?

Now the decking season starts again and the first thing I see on Biltema's website is an ad for the same drill I used for decking three years ago.

Does anyone know if they have done any product development or if it's the same crap as before?

It's hardly the same screws; they're in your deck...

It could just as well have been a bad batch that you got your hands on...

Using them correctly and not overtightening is also important...

It's hardly the same screw, as it's in your decking...

It's also important to use it correctly and not overtighten..

It's almost difficult to over-tighten deck screws with such a small head in pressure-treated decking. It has to be able to pull down into the decking.
