Specially developed full-thread screw for fastening the cabinet connector for screw mounting in the KALTSCHMELZ® anchor

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

Flat fastening metal sheets for secondary purposes

  • Flat, cylindrical pan head rounded with a lens

  • Large surface contact area

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

Ideal for friction-free screw fitting in plastic, such as in anchors or in homogeneous highly compressed wooden materials

  • Screw bites rapidly through the continuous thread design to the tip of the screw

  • Non-spreading screwing in thanks to tip geometry without any component to reduce splitting
  • Do not use the screw in applications with direct exposure to the elements or in humid rooms with atmospheres containing chlorine gas. If used outdoors and in rooms that are constantly exposed to high humidity, please use ASSY 4 A2 PH stainless steel screws

Application area

For steel-wood Kaltschmelz anchor connections designed for tensile forces

The full thread starting immediately below the head allows for e.g. Fitting-Kaltschmelz-anchor connection possible. Greater screw pull-out force is achieved by the maximum thread length.

For applications in utilisation class 1 and utilisation class 2 (from ∅ > 4 mm)

  • High-quality surface protection zinc blue passivated chromium(VI)-free, up to ∅ 4 mm A2K 5 µm, from ∅ 4.5 mm A3K 8 µm layer thickness

  • Suitable for use in utilisation class 1 (interior) and from a ∅ > 4 mm in utilisation class 2 (wet area or covered outdoor area) according to EN 1995-1-1:2010-12 + DIN SPEC 1052-100:2013-08

  • For screws from ∅ 4.5 mm with zinc layer thickness 8 µm with Cr(III) passivation, the requirement of classification T2/C2 is fulfilled in accordance with prEN 14592:2017 (D)

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