Specification

Special collated full-thread screw with countersunk head with milling pockets for series fastening of particleboard flooring in indoor dry or wet areas

Ideal power transmission thanks to RW drive

More power due to larger contact area at the bit

More stability, one-handed working, precise positioning due to the tight-fit recess and perfect fit of the bit

Fewer bit changes, one bit for many screw diameters

Compatibility with previous AW drive

Easy countersinking in hardwood/softwood with high knot content as well as hard wood fibreboards

Very high milling performance due to milling ribs located at the countersunk head

No over-tightening or stripping and high feed

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

Better anchoring thanks to higher thread flanks

Ideal for friction-free screw fitting in plastic, such as in dowels or in homogeneous highly compressed wooden materials

Screw bites rapidly through the continuous thread design to the tip of the screw

Non-spreading screwing in thanks to tip geometry without any component to reduce splitting

Notice

We recommend using the Würth software or the corresponding design aids for planning and dimensioning your assembly. Use the Würth timber construction software for dimensioning of ASSY screws from a diameter of 5 mm

Do not use the screw in applications with direct exposure to the elements or in humid rooms with atmospheres containing chlorine gas. If used outdoors and in rooms that are constantly exposed to high humidity, please use ASSY 4 A2 or A4 stainless steel screws and, if atmosphere contains chlorine, HCR stainless steel screws

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

Application

Application area

Quick series fitting for panel material-wood connectors

For all manual trade applications

With hand-held devices for collated screws

The full thread starting immediately below the head allows for e.g. panel material to wood connection possible. Greater screw pull-out force is achieved by the maximum thread length.

For applications in utilisation class 1 and utilisation class 2 (from ∅ > 4 mm)

High-quality surface protection, zinc, blue-passivated chromium(VI)-free 5 µm layer thickness

Suitable for use in utilisation class 1 (interior) and from ∅ > 4 mm in utilisation class 2 (wet area or covered outdoor area) according to EN 1995-1-1:2010-12 + DIN SPEC 1052-100:2013-08

Instructions

ASSY screws are approved for quasi-static loads

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

Full-thread screws are suitable for reinforcing and creating high-load-bearing connections of two components. Components should be connected without any gap
