Just laid 40m2 of decking during the vacation with this screw. They've already started breaking. Will have to replace all the screws before the rest go too. [image]

But who in the world is so dumb to buy pressure-treated joists and decking for big money and then skimps on quality by buying substandard screws to save a little money? Also, puts in a lot of work cutting the joists and decking wood and installing everything with poor screws.

Sounds completely insane.
Just went to Biltema.
They recommend filing a damage report.
To compile the cost of the damage, extra work, cost of the substandard screws, etc. Then they will take this centrally & look at possible compensation.
Hope you also file a damage report so they get more such cases.

A friend of mine used Essve deck screws, and a large portion had broken after just the first winter. The hardware store received numerous complaints, but Essve just passed the blame and didn't take any returns, so the hardware store completely removed Essve from their decking screw range.

Now, as I'm building myself, I've only used Gunnebo's stainless steel deck screws. The hardware store had them at a great price too! Some things you simply shouldn't skimp on, especially those exposed to the elements.

But who in the world is so foolish to buy pressure-treated beams and decking for large sums of money and then ignore quality by buying substandard screws to save a bit of money? Furthermore, putting in a lot of work to cut beams and decking wood and assemble everything with lousy screws.

Sounds utterly insane.

You know that not everything is top-notch just because it's expensive, there are many items at Biltema that are equivalent in quality but much cheaper. Take, for example, anchor screws and various other bolts that others have written about, and in many cases, they've been over-torqued. So people who can't read the text description other than labeling something as "pure crap" just because it's from Biltema.

Then one might wonder instead who has the energy to sit down and declare people idiotic with poorly worded and completely irrelevant posts, since, as you've surely read, it's something done in the past and therefore can't be changed now other than by going into the concerned store to return the items and possibly look into replacement claims. But I guess you've never bought "crap" yourself ever, so congratulations that you've never had to undertake similar actions, but please keep such demeaning comments to yourself in the future.

I think that those who sell should have quality controlled their products, otherwise they should compensate even for rework.
Often they write that the screws follow a norm or standard according to some number, etc.
But WHO checks that they really meet and fulfill the requirements of that norm? No one in many cases.

There is no shortcut to quality, unfortunately. I tried Byggmax decking screws when my Essve ran out and it was Sunday (everything except Byggmax is closed), but those broke as well, so I had to go back to Essve again :P
 
It's really great that you're warning others about this screw. (y)(y)(y)
But surely you still have stainless decking screws for the patio???
I used stainless from byggmax. Super quality!
 
I have had the same problem with Biltema's deck screws
 
Don't know if anyone has brought this up, but I believe it's the timber that's the issue if screws are breaking. Have screwed in hundreds of square meters of decking in recent years, and we almost always use essve C4 on tape, sometimes we use XL screws, can't remember the name. We've never had problems with screws breaking or removing screws after a few years.

Doesn't matter... If it states that the screw should handle certain things, as a consumer you have to rely on that information. It's like buying a car, if I buy a Ford instead of a BMW. Should you assume that the Ford will break down faster just because it's not classed as a "Premium car"? Doesn't matter if you buy screws or roof tiles, etc. You can always get a bad batch, and most likely that's what happened here. I don't know how many hundreds of millions of screws they churn out but they can't all be rubbish.

I agree. Now I know that C4 is a worse choice, but when I bought at byggmax:
“Hardened wood screw with countersunk head for use both indoors and outdoors. Coated with Protect 4 to withstand tough environments.”
I didn't think for a second that several screws would break when I built a temporary scaffold with small load. I screwed planks flush against the joists and when I dismantled, there were many screws that had broken, which wasn't noticeable when I screwed them in.
Wanted to mention that you shouldn't screw together a scaffold but nail it together, the nails usually give a warning before they plan to give up.
 
I've had problems with stainless screws that break off during unscrewing (after several years) because the threaded part has rusted away.

Someone claimed that the impregnation caused it...

I just want to share a warning about Biltema's decking screws, see pictures below. I laid 20 sqm decking in the spring of 2018, the first 15 with screws of an unknown brand and about 5 sqm with Biltema screws. There are no problems with the unknown brand, but now I notice that about 90% of Biltema's screws have simply snapped. You have to look hard to find worse crap, and I hope not many of you have bought and used the same junk!

Having the exact same damn problem, a large number have snapped right off :-(
Bought the screws during the summer. In Gävle.

Mine were purchased in May 2018. In Skåne.
 
It should be added that it is not a waterproofing problem, screwed into composite. Boards pre-drilled.
80% have broken. So far... Cannot recommend these screws...
 
A bit OT perhaps, but I also want to warn about Biltema's plastic cable clips. After 2 years, most of them have just broken off and the cables are now held by only a few clips. But they are the cheapest... ☹
