Special partial thread screw made of high quality austenitic A2 stainless steel with small raised countersunk head and milling ribs. Suitable for visually appealing fastening, close to edges without pre-drilling of wooden facades, 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 bits)

Precise positioning on hard surfaces without slipping thanks to centring pin

Quick screwing 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

Optimal 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. Use the Würth timber construction software for dimensioning of ASSY screws from a diameter 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-wood connections designed to pull together

A wood-wood connection designed to pull together is possible owing to partial thread starting immediately after the shank. The thread in this case is positioned entirely in the lower second component.

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
