ASSY^® 4 A2 RCS wood façade screw A2 stainless steel plain partial thread raised countersunk head

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

Form-fit connection of the 90° countersunk head to metal fittings with 90° countersinks or in wooden products with high bulk density

• Visually appealing connections due to lens-shaped, rounded head


• Pulling together without head milling due to lack of milling elements and head is inserted by pressing

Higher breaking torque

• Higher power transmission in hardwoods due to reinforced, asymmetrical thread flank geometry of the single thread


• Better anchoring thanks to higher thread flanks

Smooth thread start ensures optimised recessing and biting of the screw

• Reduced splitting effect due to displacement effect of the dome-shaped milling elements in the tip


• Friction-reduced thread rotation allows reduction of the screw-in force to be applied

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 fastening
