Série de Chumbadores e Fixações de Expansão
Mechanical and chemical anchors for concrete, masonry, brick and hollow wall. Drop-in, sleeve, frame, elevator, hammer-drive, hollow wall and 4-piece anchors, plus chemical anchors, expansion hooks and eye bolts.
Chumbadores de encaixe interno (drop-in)
Drop-in anchors with an internal thread and a pre-expanded sleeve, set flush into a drilled hole so a bolt or threaded rod can be fitted afterwards. Ideal for overhead and shallow-depth fixing.
Chumbadores usinados (machined)
Machined sleeve anchors supplied as a stud, expansion sleeve, nut and washer in one assembly. The sleeve expands against the hole wall as the nut is tightened, giving high pull-out resistance in concrete.
Chumbadores para esquadria metálica (metal frame)
Metal frame anchors for fixing door and window frames into concrete or brick. The zinc-plated sleeve and pin are set into the hole and expand when driven, holding the frame without a separate bolt.
Chumbadores autoatarraxantes para concreto
Concrete self-tapping anchors that cut their own thread into a pre-drilled hole, so no expansion sleeve is needed. Removable, re-insertable, and suitable for use close to concrete edges.
Chumbadores de fixação por martelo (hammer drive)
Hammer drive anchors set with a single hammer blow. The pin expands the sleeve as it is driven home, giving a fast permanent fixing for brackets, conduit clips and light framing.
Chumbadores para elevador
Elevator anchors with a long sleeve and a hex head bolt, designed for the deeper embedment and higher load requirements of lift guide rails and other heavy equipment fixing.
Chumbadores tipo "árvore de Natal" (christmas tree)
Christmas tree anchors with a ribbed, tapered body that expands along its length as the screw is driven. Suited to brick, aerated concrete and other low-strength base materials.
Chumbadores químicos
Chemical anchors combining a threaded rod with a two-part resin capsule or injection mortar. The resin bonds the rod to the full depth of the hole, producing high load capacity and good vibration resistance.
Chumbadores de luva com flange
Flange sleeve anchors with a wide flange collar that seats against the fixture and spreads the bearing pressure, for fixing into concrete and solid brick.
Chumbadores de luva sextavados
Hex sleeve anchors for general-purpose fixing into concrete, brick and block. The expanding sleeve grips the hole wall as the screw is tightened.
Chumbadores para tijolo de concreto celular (bubble brick)
Expansion anchors designed for aerated (bubble) brick and other lightweight blocks, where the body spreads over a larger area to develop holding strength in low-density material.
Chumbadores sísmicos (seismic-resistant)
Seismic-resistant anchors with a rubber-cushioned sleeve that absorbs vibration and accommodates movement, used for suspended services and equipment in seismic zones.
Chumbadores de expansão de 4 segmentos
Four-piece expansion anchors whose segmented sleeve expands evenly on all four sides, giving a secure grip in concrete and solid masonry over a wide contact area.
Chumbadores para parede oca (hollow wall)
Hollow wall anchors with spring-loaded toggle wings that open behind the board and clamp it from the reverse side. For plasterboard, hollow-core doors and other thin panels.
Buchas de expansão (wall plug)
Wall plugs for light-duty fixing into brick, block and concrete. The plug expands as the screw is driven to grip the hole wall.
Ganchos-suporte para aquecedor de água
Water heater bracket hooks for suspending electric water heaters and similar appliances from a wall. Supplied with expansion plugs matched to the hook shank.
Ganchos de expansão
Expansion hooks combining an open hook with an expanding sleeve, for hanging cables, conduit and light fittings from concrete or brick ceilings and walls.
Ganchos de olhal (eye fix bolts)
Eye fix bolts with a forged closed eye and an expanding sleeve. Used as a permanent anchor point for guy wires, chains and light lifting duties.
