Special partial-thread screw made of high-quality, austenitic A2 stainless steel with small, raised countersunk head and milling ribs for visually appealing fastening close to edges, without pre-drilling, of wooden façades, skirting boards, fences, etc. in outdoor areas constantly exposed to weathering

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 bit)

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

  • Quick fastening due to gentle start of thread


Clean countersinking in softwood/hardwood with high knot content


  • Small, lens-shaped 60° countersunk head for visually appealing connections

  • Very high milling performance due to milling ribs located at the countersunk head


Maximum reliability of the screw connection due to asymmetrical single thread


  • Optimum matching of drill tip and thread geometry

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


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 screwing
Notice
  • We recommend using the Würth software or the corresponding design aids for planning and dimensioning your assembly. ASSY screws can be dimensioned in the Würth timber construction software from a ∅ 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 wood to wood connections designed to pull together


The partial thread starting immediately below the shank allows for wood to wood connections designed to pull together. The screw thread is positioned entirely in the lower second component once screwed in.

Instructions
  • For optimum use of the screw, use the RW bit that fits exactly

  • Partial threaded screws are ideal for connecting wooden components. To achieve optimum component assembly, the component thickness to be joined tightly must not be greater than the shank length

  • ASSY screws are approved for quasi-static loads

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).
