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

RW recess ensures optimal power transmission

Larger contact surface at the bit offers increased power

More stability, one-handed working and precise positioning due to the tight-fit recess and perfect fit of the bit

Fewer bit changes, one bit for multiple screw diameters

Compatibility with previous AW recess

Easy countersinking in hardwood/softwood with lots of knots as well as in hard manufactured boards

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

Reduced splitting of component to be mounted when inserting the screw

Very high milling performance due to milling ribs located in the countersunk head

Maximum reliability of the screw connection due to asymmetrical coarse thread

Optimal combination of drill tip and thread geometry

Excellent anchorage in wood due to asymmetrical arrangement of thread flanks

Precise positioning and very clean drilling due to advanced centring drill tip

Chip-free positioning and drilling

Powerful and precise drilling due to drilling cutting edges (similar to a Forstner bit)

Centring pin ensures precise positioning on hard surfaces without slipping

Quick screwing due to gentle thread start

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

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

Can be used in a rural or urban environment or in an industrial atmosphere without significant exposure to chlorides or SO₂

With anti-friction 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

Certificates/ Documents

Application area

For fastening two timber elements without leaving a gap.

The underhead thread has a reduced thread pitch and enlarged external diameter, allowing two wooden elements to be connected without leaving a gap. The screw head can be made flush with the material surface.

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
