R-ONR-55/63 Self-drilling screws for fixing sandwich panels to steel construction up to 12 mm, zinc-flake 6.3/5.5x121 mm with washer A19 RAL 7016 - cardboard box - 100 pcs.

Highly effective protection is provided by a special zinc flake corrosion-resistant coating. The self-drilling tip's unique approach angle enables direct installation without predrilling, up to 12mm. A self-vulcanizing EPDM washer, resistant to temperature and UV, ensures proper sealing. The washer's shape guarantees a secure fit on the outer cladding material. The thread's design and height are ideal for sandwich panels and steel construction. A coloured polyester protective coating, 45-50um thick, offers additional corrosion resistance. Available in various colours to match all metal sheet variants, with UV stabilizers for long-lasting colour quality. Two thread types: one for steel structures, the second under head thread to prevent panel dents and aid sealing. The screw's thread surface is hardened, and a high-quality anti-corrosion coating ensures 15 Kesternich cycles resistance.
