Universal partial-thread screw with underhead thread with high tightening effect for fast, gap-free fastening of wood-wood connections in furniture construction, interior construction or wood construction in indoor dry or sheltered 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

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

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

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

ETA-11/0190 approved

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

Application area

For connecting two wooden elements without assembly gap

The underhead thread beneath the head with reduced thread pitch and enlarged external diameter allows two wooden elements to be connected without assembly gap. A flush connection of the screw head with the material surface is possible.

For wood-wood connections designed to pull together

The partial thread starting immediately below the shank allows for wood-wood connections designed to pull together. The screw thread is positioned entirely in the lower component once screwed in.

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

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

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

For screws from ∅ 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

ASSY screws are approved for quasi-static loads

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

Partial-thread cabinet screws are ideal for joining light wood materials such as chipboard. To achieve optimum component assembly, the component thickness to be fixed must be greater than the shaft 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
