Double thread screw ideal for securing roof insulation and façade mounting using soft or pressure-resistant insulating materials

Steel, blue zinc-plated, double thread, cylinder head, AW drive

Head:

Small cylinder head — ideal for sinking into wood

Thread:

A coarse, single-flight asymmetrical thread reduces the screw-in time by 30%

Plastic non-friction coating:

Enables easy screw-in due to sharp threads with glide-promoting coating

Tip with counter thread:
•Reduces the tendency of the wood to split
•Reduction of the screw-in torque

AW drive:

Optimum centring

Largest possible contact surface of the bits in the tip, thus no ejection forces

Combination/replacement products:

ASSY 3.0 SK

ASSY plus FT

Notice

ASSY Isotop is screwed into the rafters, for example, through the securing battens and insulation without pre-drilling. For very dry wood (e.g. old building renovation) we recommend pre-drilling the securing battens with 8 mm.

You can use the Würth timber dimensioning software for an individual structural recommendation. Use this formula to easily calculate the screw length (specified in mm).

ETA–11/0190

When using these screws, please follow ETA-11/0190 specifications.

Application area

Attachment of the insulation layer for rafter-insulated gable roofs and curtain-wall façades to insulation layers.

Instructions

Roof application 1

With soft insulation < 0.06 N/mm²

For soft insulation with a pressure resistance below 0.06 N/mm², such as fibreglass, mineral wool, animal and plant eco-insulation = use an alternating screw-in pattern at an angle of 60° to the rafter axis.

Roof application 2

With pressure-resistant insulation > 0.06 N/mm²

For non-slip insulation with a pressure resistance above 0.06 N/mm², such as hard polyurethane (PUR) or polystyrene (PDS) foam = parallel screw-in pattern at an angle of 60° to the rafter axis.

Calculation of the required screw length:

Thickness of securing battens in mm

+ thickness of insulation in mm

+ thickness of boarding in mm

+ 60 mm screw-in depth

Intermediate result in mm x a factor of 1.15

Final result in mm

Use the next longest screw length

The packaging unit defines the number of articles in one packaging. In the catalog segment you can choose from different packaging units if a pop-up menu is displayed.

Just leave the field empty if you don't know the packaging unit when directly entering the article number in the shopping basket or when importing with Easy-/VarioScan. The packaging unit will be determined automatically.

The article number is made up of the following: VVVVAAABBB
VVVV = 4 digits for prefix number (please note that the first digit is currently always 0)
AAA = 3 digits for dimension part 1
BBB = 3 digits for dimension part 2

Example article number structures:
Example 1: Screw with dimensions of 4x10 mm:
VVVVAAABBB
00574 10 (2 spaces between the 4 and the 10)

Example 2: Screw with dimensions of 10x20 mm:
VVVVAAABBB
005710 20 (1 space between the 10 and the 20)

Example 3: Flat washer with an internal diameter of 6 mm:
VVVVAAABBB
04076
