Thickness 6 - 12 mm

0.75 - 1.25 mm steelor 2.5 mm aluminium

Item 1 Item 2

Existing solution: Wing type screw

Function of wing screws

The wings enlarge the hole in the soft material

Drill the steel and thread form into the steel

+ =

But: It only works if the wings are stronger than the first material and

weaker than the steel ! In thin steel they often do not break off but drill a large hole.

The wings break when they contact steel

Our challenge

We were looking for a high quality stainless steel fastener that works in every case

Can be used in thin steel Independent from material density, machine speed etc Nice aesthetical head which can be colour matched

Our solution: Wobbel screw SDF2

Function:

Function: it's wobbling around the excentric drill point

Function:

Function:

Function: the point drills the steel

Function:

Function: it clamps the two material properly together

Features

No problems with wings which are breaking too early (hole is not enlarged) or too late (no pull out load)

Easy installation of cladding panels High quality stainless steel fastener A2, AISI 304 Suitable for thin materials (0.75 - 1.25mm steel), so the structure

could be made in thinner steel to save money Suitable for soft materials (aluminium) For hard cladding panels (fibre cement etc) Competitive price
