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

Information on price and image display

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

Hardened steel, zinc-plated, yellow coated, partial thread, large washer head, AW drive, counter thread


  • Connects the wood instead of splitting it


Surfaces:


Solid wood (coniferous wood, ash, beech, oak), laminated beams, cross laminated timber (CLT) timber veneer (coniferous wood or BauBuche), OSB and chipboard.


Large washer head


  • Very high penetration resistance or consolidation


AW drive – more power


  • Optimum transmission of forces

  • Very good snug fit

  • Fast location

  • Screw settles securely

  • Almost no unscrewing of the bit

  • No wobbling

  • No damage to surface coating of screw

  • Only 3 bit sizes for the diameters 5.0 to 12.0 mm


End mill – the "auxiliary motor" for low force


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

  • Protection of screw-in tools

  • From diameter = 5 mm, L = 70 mm


Asymmetric coarse thread – faster speed


  • Low screw-in torque

  • High over-turning force

  • Faster screwing than conventional chipboard screws – reduces processing 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

  • Blow-outs are avoided to a high degree thanks to the punching effect of the ring thread
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.


ASSY 3.0 chipboard 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 follow ETA-11/0190 specifications.


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