Roller-sorted full-thread screw with raised countersunk head and restraining ribs for gentle attachment of window fittings in wood in indoor dry or wet areas, suitable for use in vending machines

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, 1 bit for many screw diameters

  • Compatibility with previous AW drive


Visually appealing fasteners in window construction


  • Lens-shaped, rounded head for a visually appealing window fitting connection

  • The spring-loaded effect of the restraining ribs prevents the screw from overturning and destroying the head


Less tendency of the wood to split and very few blow-outs


  • Blow-outs are avoided to a high degree thanks to the punching effect

  • Minimal splitting forces, especially when screwing in at edges

  • Reduction of the screw-in torque
Notice
  • We recommend using the Würth software or the corresponding design aids for planning and dimensioning your assembly. Dimensions of the ASSY screws can be carried out in the Würth timber construction software from a ∅ 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 is chlorine-containing, 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

Quick series screw connections


  • For screwdriving machines

  • Screw demagnetised after the manufacturing process

  • Interference-free as foreign objects are sorted out of the screw packaging


For steel-wood connections designed for tensile forces


The full thread starting immediately below the head allows for e.g. fitting-wood or sheet material-wood connections designed for tensile forces with high load-bearing capacity. 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 8 µm layer thickness

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

  • 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

  • Full-thread screws are suitable for secure mounting of fittings or thin materials. The screw length to be selected should be less than the plate thickness of substrate the screw is to be driven in

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
04076
Price per packaging unit (PU):
The displayed price is always in line with the displayed packaging, if the PU is 250 the price for 250 units, if the PU is 300 the price for 300 units.

Price with price key representation (PSL):
The price always applies to a quantity ruled through the price key:
Price for 1 unit
Price for 100 units
Price for 1000 units
The quantity shows the number of pieces or units of measure contained in the order or delivery for the respective article.
In contrast to sales packaging and secondary packaging, the disposal costs for chemical-technical products are shown separately. The breakdown of the individual costs can be found on the relevant products and also in the shopping cart, as well as in our General Terms and Conditions (GTC).
