All versions

Specification

For exceptional applications in utilisation classes 1 and 2. Combines the robustness of a steel screw with excellent rust protection thanks to an extremely corrosion-resistant surface in atmospheres containing salt.

Corrosion resistance is five times greater than a yellow zinc-plated surface (500 h in salt spray test as per DIN-EN ISO 9227)

Its coating gives the ASSY screw a high-quality stainless-steel appearance

Chrome VI-free

Asymmetrical thread

Prevents overturning and makes screwing in easy

AW drive

For perfect bit clamping

Milling pockets

For clean countersinking — in fittings as well

End mill

For less friction on the shaft (with diameters of 5 mm or more and lengths of 70 mm or more)

Ring or mating thread

At the tip, enables screwing close to the edge

Notice

Screws may not be used for

Wood containing large amounts of tannic acid

Boiler-pressure impregnated wood

Direct weathering (utilisation class 3)

ASSY 3.0 chipboard screws are optimised for use in wooden materials. Use in plastic dowels may cause a reduction in the load-bearing capacity. Therefore, we recommend only using screws without optimised thread tips (drill tip, mating thread, ring thread, serrated edge, self-clearing groove etc.) in plastic anchors, e.g. ASSY D, DIN 571 hexagon wood screws or Wüpofast screws.

To attach metals to wood, machine a precise cut-out in the metal tab.

ETA-11/0190

When using these screws, the ETA-11/0190 specifications must be observed.

Application

Application area

Suitable for use outdoors in accordance with utilisation class 2 (NKL 2) DIN 1052:2008 (covered, open structures)

Instructions

Screw-in angle 0° to 90°. For coniferous wood or wood-based materials made from softwood, the screw connection is made without pre-drilling. To reduce the edge distances, a pre-drilled hole can be made according to the core diameter. When screwing into hardwood, pre-drill according to ETA-11/0190.
