Partial thread screw with underhead thread countersunk milling head and high joining effect. Suitable for gap-free fastening, close to edges without pre-drilling of wooden composite boards or solid woods. The firm hold of the underhead thread enables connections without an assembly gap even with lightweight wooden fibre boards and the screw head ending at the board surface.

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


Precise positioning and very clean drilling due to advanced centring drill tip


  • Positioning and drilling without chipping

  • Maximum drilling performance and precise drilling process through drilling cutting edges (similar to Forstner bits)

  • Precise positioning on hard surfaces without slipping thanks to centring pin

  • Quick screwing due to gentle start of thread


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


Maximum reliability of the screw connection due to asymmetrical single thread


  • Optimal matching of drill tip and thread geometry

  • Excellent anchoring in wood due to asymmetrical arrangement of thread flanks


High strength values and ductility


  • Adjusted heat treatment guarantees high strength values and high ductility
Notice
  • Do not use the screw in applications with direct exposure to the elements or in humid rooms with atmospheres containing chlorine gas. Please use ASSYplus 4 stainless steel screws for outdoor applications and rooms with constant high humidity

  • 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

  • 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


A wood-wood connection designed to pull together is possible owing to partial thread starting immediately after the shank. The thread in this case is positioned entirely in the lower second component.



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
  • 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 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

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
