Specification

Special collated partial thread screw with long belt and combined underhead thread for fast, gap-free fastening of wood-to-wood connections in furniture construction, interior construction or timber construction in dry indoor or damp areas

Ideal power transmission thanks to RW recess

More power due to larger contact area at the bit

Maximum overtightening safety with high feed performance

Higher power transmission in hardwoods due to reinforced, asymmetrical thread flank geometry of the coarse thread

Better anchorage thanks to higher thread flanks

Strong gap-free assembly of components using a second supporting underhead thread with flat incline

Smooth thread start ensures optimised recessing and biting of the screw

Low gap effect due to displacement effect of the dome-shaped milling elements in the tip

Notice

We recommend using the Würth software or the corresponding design aids for planning and dimensioning your assembly. Dimensioning the ASSY screws can be carried out in the Würth timber construction software from a ∅ of 5 mm

ASSY 4, ASSYplus 4 and ASSYplus 4 FT chipboard screws are optimised for use in wood and wood materials. For applications in plastic anchors where load capacity can also be reduced, use only screws without an optimised thread tip (tip with milling ribs, drill tip, self-clearing groove etc.), such as the ASSY D screws with countersunk head or pan head

ETA-11/0190 approved

The requirements of the European Technical Approval (ETA) must be observed

Application

Application area

Quick series screw connections

Gap-free fastening of tongue and groove planking, packaging and cladding in a wooden substrate

Can be used for applications in indoor and wet areas under the conditions of Class 1 and 2 in accordance with EN 1995-1-1 Section 3.1.5

Instructions

Magazine-fed screwdrivers or attachments designed for long belt processing must be used for fixing screws arranged in a long belt

For optimum use of the screw, the right-size RW bit must be used

Partial-thread screws are ideal for connecting wooden components

ASSY screws are approved for quasi-static loads
