Série de Parafusos Autobrocantes (Self-drilling)
Self-drilling and self-tapping screws that drill, tap and fasten in a single operation. Hex head, pan head, countersunk and clipped-ear variants in stainless steel, carbon steel with colour zinc, paint-baked and composite-washer finishes, plus drywall and fiberboard screws.
Parafusos autobrocantes de cabeça sextavada em aço inoxidável
Hex washer head self-drilling screws in stainless steel, for fastening metal sheets to steel framing where corrosion resistance is critical. The integrated washer face spreads the clamping load and the drill point taps its own hole, so no pre-drilling is needed. Typical for roofing, cladding and outdoor steelwork.
Parafusos autobrocantes de cabeça sextavada em aço carbono com zinco colorido
Hex head self-drilling screws in carbon steel with colour zinc plating — a yellow-iridescent finish that outlasts standard clear zinc in outdoor and humid service. Suited to general steel-to-steel fastening in construction and light engineering.
Parafusos autobrocantes de cabeça sextavada com arruela composta
Hex head self-drilling screws fitted with a bonded EPDM composite washer. The sealing washer keeps water out of the fixing point, making these the standard choice for metal roofing and cladding sheets.
Parafusos autobrocantes de cabeça sextavada com pintura curada (paint-baked)
Hex head self-drilling screws with a paint-baked finish, supplied in colours matched to the panel — commonly RAL tones. The coating protects the head and blends the fixing into the finished facade.
Parafusos autobrocantes de ponta aguda
Pointed-tail self-drilling screws for fastening timber to steel and for general woodworking, where the sharp point starts the fixing without a pilot hole. Yellow zinc plated with a Phillips drive.
Parafusos autobrocantes de ponta relâmpago (lightning tail)
Lightning-tail self-drilling screws with a milled cutting tip that clears swarf faster and lowers the driving torque required through thick steel. Ideal for heavy-gauge sheet and steel-to-steel assemblies.
Parafusos para fibra de madeira (fiberboard)
Fiberboard screws with a fine thread and sharp point for joining fibreboard, particleboard and MDF panels. The countersunk head sinks flush with the board surface.
Parafusos para drywall (gesso acartonado)
Drywall screws with a bugle head and fine thread for fixing plasterboard to timber or metal studs. The bugle head crimps the paper face without tearing it and finishes flush under filler.
Parafusos autoatarraxantes de cabeça com arruela
Washer head self-tapping screws with a large integral flange that distributes load over a wider area. Used for thin sheet, plastics and softer materials where a standard head would pull through.
Countersunk Head Self-drilling Screws
Countersunk head self-drilling screws that drive flush with the work surface, used where a flat finish matters and no head protrusion is acceptable — metal panels, trim and fascia.
Parafusos autobrocantes de cabeça panela com fenda Phillips
Phillips recessed pan head self-drilling screws — the general-purpose fixing for sheet metal ducting, cabinets and light steel assemblies. The pan head gives a clean, low-profile finish.
Parafusos autobrocantes de cabeça escareada com abas
Countersunk head self-drilling screws with clipped ears. The notched head self-countersinks into wood and composite material, leaving a flush surface without pre-countersinking.
