Warning for Biltema's decking screw

[optimum]

You can't compare with the fact that Biltema's screws worked well 5 or 10 years ago, as Biltema changes suppliers and puts its brand on them. Therefore, the quality of the goods can range from crap to premium.

Yes, I know some of the items they sell are exactly the same as premium brands. Coming from the same factory and exactly the same, just different packaging. 100% the same.

The problem is not just the quality of the screw but also the fast-growing poor-quality spruce wood that absorbs a lot of water and thus moves a lot is used, as well as poor installation. Use properly dimensioned, knot-free joists against the floor. Buy dense wood, preferably pine, and pre-drill with 2.5-3 mm and lay with 5-6 mm edge measurement to get a nice floor without drying cracks and without broken or pulled screws. For this material, you can use stainless or hardened screws as the movement in the joists and floor is much less. Pre-drilling reduces the load on the screw and the stress in the wood around the attachment, allowing the wood to move slightly. Use quality screws of the right length and a non-impact machine. Sink the screw head flush with the board using the machine, then manually with the machine another 1-1.5 mm, this prevents excessive torque on the screw. Never use 22 mm but at least 28 mm wood which is usually of better quality. All this costs 30-50% more but provides a worry-free deck floor. Before building, read up on wood quality and sorting. Have used screws of all brands without problem.

Well, these tips suggest that Biltema screws are indeed good, but that's probably not the case. Moreover, I wonder who has the patience to pre-drill for all screws when laying decking? Not me, except possibly in exceptional cases.

I will definitely do that, I just haven't gotten that far yet. I just hope it won't be a problem that I'm missing the receipt...

Email and tell them which card you purchased from and if you remember the day. They have helped me get a receipt for accounting that way! It'll work out!

I have discovered the same thing with another wood screw that Biltema sells, article no. 87-0280 and other dimensions in that series, what crap.

What did you fasten with it?
Unfortunately, I used them to screw some panel on a gable when my other screws ran out, none broke, but I wonder if they will break on their own soon?

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

Happens often with esseve's screws too.

I would say the same applies to Julas trallskruv. They snap one after another already during assembly. Hardhead that is.

That over 75% breaking is extreme; there must be a common factor increasing the risk of them breaking. I believe all the mentioned brands have affected someone in this thread, so it's not brand-related, and no retailer wants to sell such crap. Byggmax had their own brand two years ago, blue boxes. Those screws were crooked in the box and quickly disappeared from the assortment.

I drove in 6-7000 deck screws from Grabber in the pool deck in 2017, and now after three years, everything is intact. Closest to the pool, 2000 were stainless steel, and the rest C4. However, Grabber's own screw head was crap.

But why do they break? A thought, how many of you have been screwing with a drill that has an impact mode and doesn't turn smoothly? The impact puts significantly greater stress on the screw, which weakens it.

Furthermore, was it cold screws that were driven in or summer warmth?

I built a temporary scaffold up to the chimney top to renovate it a year ago and dismantled it now. I also used screws from Jula Hard Head for this construction, and not a single one had broken. I used a regular drill that turns smoothly and does not impact or hammer.

Has anyone tried ESSVE’s hidden (with the special tool)?
/L

I have installed decking with so-called hidden screws, though not ESSVE's, but Heco's with their tool. No screws have broken during installation, but I don't know how it will be in a few years since I installed some decking last year and some this year. The decking is 28x120.

But who in the world is so dumb that they buy pressure-treated joists and decking for big money and then ignore quality by buying substandard screws to save a little money?
Additionally, they put in a lot of work cutting the joists and decking and assembling everything with crappy screws.

Sounds completely insane.

A receipt is never needed for a complaint as long as you, as a customer, can prove that it is, for example, Biltema's screws, meaning you bought the item from the chain you are lodging the complaint to. And that's not too difficult since they have their specific appearance plus the packaging if you still have it. However, you can be denied a return if you lack a receipt, but that's a completely different matter.

A few weeks ago, I made a complaint about a boat seat bought at Biltema. No receipt, but it was fine to show my phone with the account open where you could see the amount (we had bought more items). They then searched for the date in the register and matched the amount we showed, and voila, they found the transaction. Then it took about two banking days, and the amount was refunded.

They will probably replace the bad screws. But the annoying thing is that the work has to be redone and they likely won't compensate for that.
This is something you encounter all too often. I think those who sell should have quality-controlled their products, otherwise they should compensate even for the rework.

But who in the world is so stupid to buy pressure-treated lumber and decking for large sums of money and then disregard quality and buy substandard screws to save a little money? Also laying down a lot of work cutting the lumber and decking and assembling everything with subpar screws.

Sounds completely insane.

Well, we ordinary poor sinners who, until we read this thread, thought that A4 was just a paper sheet and that C4 was just a type of explosive. For example.

So far, I've also relied on the text on the box. Thought that was the reason it was there.

You'd have to look hard to find worse crap and I hope not many of you have bought and used the same junk!

Oh no, this warning should have come 2 months ago, now my decking is screwed with those screws
