Specification

Special partial-thread screw with underhead thread with high tightening effect made of high-quality, austenitic A2 stainless steel with small countersunk head and milling ribs for flat, gap-free attachment close to edges, without predrilling, 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

Easy countersinking in hardwood/softwood with high knot content as well as hard wood fibreboards

Small 60° countersunk head and therefore narrower geometry for use in seams or with tongue-and-groove connections

Reduced splitting of component to be mounted when immersing the screw

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

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

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

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. Dimensions of the ASSY screws can be carried out 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

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.

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

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:
