Everything that goes with an ADIT fixing – sealing washers for the self-drilling screws, plus the bits, sockets, nozzles and tools for drilling and chemical anchoring on site.
Sealing Washers
Bonded EPDM sealing washers seat under the screw head to give a fully weatherproof, watertight fixing – the standard accessory for roofing, cladding and sheet-metal work with the ADIT self-drilling screws. Choose galvanized steel for standard work, A2 stainless where corrosion resistance is needed, or the EPDM cap for a fully sealed head.
ARANE · Galvanized + EPDM
Galvanized-steel washer with a bonded EPDM seal. Diameters 14, 16, 18 and 25 mm to suit ST 4.2–ST 6.3 screws. The standard weatherproof washer for steel and general fixings.
ARINO · A2 Stainless + EPDM
A2 stainless-steel washer with a bonded EPDM seal. Same 14–25 mm range as ARANE, but corrosion-resistant – for aluminium, exterior and humid environments.
ARPAR · EPDM Cap
Moulded EPDM sealing cap/washer that closes over the head for a fully sealed, UV-resistant finish – where a completely watertight, discreet head is required.
Drilling
Drill bits, driver bits and adapters for anchor installation.
