Packaging unit

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.

Structure of our article number

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

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


Flat fastening metal sheets for secondary purposes


  • Flat, cylindrical head rounded with a lens

  • Large surface contact area


Higher breaking torque


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

  • Better anchoring thanks to higher thread flanks


Smooth thread start ensures optimised recessing and biting of the screw


  • Reduced splitting 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


Stainless mounting for accessible wood connections in outdoor areas exposed to weathering


  • Made of austenitic, non-magnetic and non-rusting A2 stainless steel

  • Can be used in rural or urban environments or industrial atmospheres without significant exposure to chlorides or SO2

  • With friction-reducing slide coating for easy fastening
Notice
  • Austenitic stainless steel is characterised by a high degree of corrosion resistance against aggressive industrial air, sea air, tap water, river water, mine water and salt water, as well as woods containing tannic acid. It is resistant to acid to a certain extent and not suitable for atmospheres containing chlorine gas

  • 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
