Partial-thread screw with geometry and drill tip attuned to MDF for connection in MDF front faces of cabinet parts without predrilling, splitting or bulging

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, 1 bit for many screw diameters

Compatibility with previous AW drive

Screw fitting without gaps or bulging in MDF front surfaces

Optimisation and extension of the drill tip for screw fittings without gaps or bulging

Connection of MDF panels, hardwood or hard, engineered woods

For visually visible and plasterable wood-wood connections thanks to 90° head geometry with reduced head diameter

Maximum pull-out strength and minimum splitting effect

Thread attuned to MDF material

Optimum distribution of drilling chips through serrated screw core

Prevents pressing in the MDF material due to thin core diameter and extra high thread flanks

Notice

Do not use the screw in applications with direct exposure to the elements or in humid rooms with atmospheres containing chlorine gas. Please use ASSYplus 4 stainless steel screws for outdoor applications and rooms with constant high humidity

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.

Instructions

For optimum use of the screw, the right-size RW bit must be used

MDF partial-thread screws are ideal for connecting wooden plates in MDF. The specially tuned geometry and thread base form avoids pressing and splitting as much as possible. Due to the different MDF qualities, preliminary testing is required
