Screws and strength

[kimmo_thn]

Hello.

I am going to install an Elfa wall shelf system in the closet.
The wall is a simple inner wall with a single gypsum board where it is studded at cc60 behind it.

I will buy a 160cm hanging track to ensure it can be attached to the studs.

2 Montageskruv 4.2 x 50 Elförz. for attachment to the studs and 3 M6 molly expanders in the places that lack a stud.

So my question is... How much can a Montageskruv 4.2 x 50mm Elförz handle?

This is what Biltema writes:

Montageskruv
For attachment of studs, kitchen fittings, cabinets, etc., to wood or steel studs. To steel studs max. 0.7 mm. Philips cross slot no 2. Intended for indoor use. (250-pack delivered with 2 PH2 bits.) EN 14566.

The only ones who can reasonably answer what Biltema's assembly screw can handle are probably Biltema. It depends on material choice, hardening, thread pitch, inner diameter of the thread, etc.
If it is CE-marked, there is a Declaration of Performance (DOP). This specifies the permissible load value in wood with certain specifications.

This indicates the allowable load value in wood with certain specifications.

Thank you for your answer.. I will head to Biltema and talk to them someday. For now, the shelf is on the wall and nothing has come loose yet.
