All versions

Specification

Universal partial-thread screw for fast, gap-free fastening of wood-wood connections in furniture construction, interior fitting or wood construction in indoor dry or sheltered areas

Ideal power transmission thanks to RW recess

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, 1 bit for many screw diameters

Compatibility with previous AW drive

Significant reduction in the amount of force required when screwing in the screw

Low gap effect when immersing the shank due to the displacement milling effect of the milling shank

Minimised risk of screw breakage due to high breaking torque

Reduced risk of injury from protruding metal chips due to the integration of the milling shank into the thread

High protection of the application tools

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 anchorage thanks to higher thread flanks

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

Friction-reduced thread rotation allows reduction of the screw-in force to be applied

High strength values and ductility

Adjusted heat treatment guarantees high strength values and high ductility

Proof of Performance

ETA-11/0190 approved

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 area

Application

Application area

Parallel drive size RW30 is available for window applications with a diameter of 6 mm. This makes it easier to combine with AMO screws equipped with RW30.

For wood-to-wood connections designed for contraction

The partial thread starting immediately below the shank allows for wood-to-wood connections designed for contraction. In this case the thread is positioned entirely in the lower second component.

For applications in utilisation classes 1 and 2 (from dia. > 4 mm)

High-quality surface protection zinc blue passivated chromium(VI)-free, up to dia. 4 mm A2K 5 µm, from dia. 4.5 mm A3K 8 µm layer thickness

Suitable for use in utilisation class 1 (indoor areas) and from dia. > 4 mm in utilisation class 2 (wet areas or covered outdoor areas) in accordance with EN 1995-1-1:2010-12 + DIN SPEC 1052-100:2013-08

For screws from dia. 4.5 mm with zinc layer thickness 8 µm with Cr(III) passivation, the requirement of classification T2/C2 is fulfilled in accordance with prEN 14592:2017 (D)

Instructions

To increase the joining effect or head pull-through resistance, combining with perfectly fitting washers for ASSY 4 is recommended

ASSY screws are approved for quasi-static loads

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

Partial-thread screws are ideal for connecting wooden components. To achieve optimum assembly of the components, the components to be fixed must not be thicker than the length of the shank

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 v

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
