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

Hardened steel, blue passivated (A3K), graduated washer head, AW drive, end mill, partial thread, counter thread



Connects the wood instead of splitting it



Graduated washer head


  • Combines the properties of a countersunk head with those of a washer head. Transmits high forces but can be countersunk

  • Screw head is flush with the surface of the wood

  • Minimises the number of screw variants so that less stock is required


AW drive – more power


  • Optimum power transmission, excellent fit, fast location

  • No wobbling, no damage to surface coating of screw

  • Ideal for overhead work


End mill – the "auxiliary motor" for lower force


  • Reduction of the screw-in and head countersinking torque by approx. 20%, especially with long screws

  • Gentle on your tools and extends the battery life


Asymmetric coarse thread – faster speed


  • Low screw-in torque, high over-turning force

  • Faster screwing than conventional chipboard screws — reduces working time by 30%


Tip


Very precise positioning thanks to the 34° tip



Mating thread — less tendency of the wood to split, very few blow-outs


  • Minimal splitting forces, especially when screwing in at edges

  • Reduction of the screw-in torque


Surface


  • Blue passivated, A3K, Cr III, min. 8 µm
Notice

Do not use the screw in applications exposed directly to the elements, in humid rooms or in atmospheres containing chlorine gas.


For applications outdoors and in rooms which are briefly or constantly subjected to high humidity, please use the stainless steel ASSY 3.0 SK A2 screw, prefix number 0181.


Hardwood must be pre-drilled in accordance with ETA-11/0190.



Use Würth timber construction software to measure the ASSY screws with a diameter of more than 5 mm.



ASSY 3.0 particle board screws are optimised for use in wooden materials.


When used in plastic anchors, a reduction of the load-bearing capacity is possible. Therefore, we recommend only using screws without optimised thread tips (drill bit, mating thread, ring thread, serrated edge, self-clearing groove, etc.) in plastic dowels, e.g. Würth ASSY D, prefix 0151 (countersunk head) and prefix 0153 (pan head).



When using these screws, please comply with ETA-11/0190 specifications.
