Fischer SX Plus 8x40 Expansion Plug, 100 Count - Four Way Expansion For Secure Masonry Fixings

Fischer SX Plus 8x40 Expansion Plug, 100 count, targets users who need reliable fixings in concrete and masonry where an 8 mm drill hole and consistent holding power are standard requirements. With four way expansion and a 40 mm anchor length in high quality nylon, it is purpose built for mounting lamps, cabinets and other fixtures in solid building materials and perforated bricks.

Design Focused On Secure Expansion

The SX Plus 8x40 is an expansion plug made of nylon that uses a four way expansion design to transmit forces into solid and perforated building materials such as concrete, solid brick and aerated concrete. It is specified for a drill diameter of 8 mm, a minimum drill hole depth of 50 mm and an anchor length of 40 mm according to the technical data for the SX Plus 8 x 40 plug, delivered in a folding box with 100 pieces.Technical data for the SX Plus 8x40 plug

The plug uses special fixing blades that hold the wood or chipboard screw in place during installation so the user does not need to support the screw while working overhead. It accepts wood and chipboard screws between 4.5 mm and 6.0 mm in diameter, with the screw length selected to cover the plug length, the thickness of the attached object and the screw diameter. The plug neck is expansion free, which reduces expansion forces at the material surface to help protect tile and plaster during tightening.Product description and application notes

Installation Behavior And Typical Applications

The SX Plus 8x40 is suitable for pre positioned and push through installation where the plug is set into the drill hole and the screw is inserted afterward. As the plug is placed, its fixing wings fold inward to lock the screw once it is inserted, which is useful for mounting fixtures such as lamps, wardrobes, motion detectors and mirror cabinets in overhead or wall applications. When the screw is tightened, the plug expands in four directions and anchors itself in the building material, while a rotation lock reduces twisting in the drill hole for easier installation.Assembly instructions and application examples

The plug edge is pronounced and flexible so that a few hammer blows place the plug at the correct depth without sliding deeper into the drill hole, which improves control during installation in concrete or vertically perforated brick. Fischer highlights a noticeable tightening torque that signals when the screw is properly installed, helping to avoid overtightening that could damage the substrate or compromise holding power in solid sand lime brick or perforated sand lime brick. The SX Plus 8x40 is positioned for building materials including concrete, solid brick, solid sand lime brick, aerated concrete, vertically perforated brick, perforated sand lime brick, plasterboard and plastered walls, covering a wide range of interior and exterior fixing tasks.Building materials and applications list

Pack Size, Material And International Context

The SX Plus 8x40 expansion plug with article number 568008 is supplied as a 100 piece contents in a folding box, which matches the typical professional and DIY demand for small to medium projects like mounting skirting boards, trellis or TV consoles. The plug is produced in high quality nylon, designed for permanent secure hold across solid and perforated building materials, and carries a GTIN EAN code 4048962480832 for identification in distribution and inventory management.EAN and packaging data

Comparison With Other Wall Plugs

Within the category of plastic expansion plugs for masonry, the SX Plus 8x40 sits alongside other nylon plugs that use two way or four way expansion but may differ in drill diameter and anchor length. For example, a typical general purpose 6x30 plug uses a 6 mm drill diameter and a shorter 30 mm anchor length, while the SX Plus 8x40 uses an 8 mm drill and 40 mm anchor length to support higher load values in concrete and solid brick; this difference in geometry increases the volume of material engaged in the substrate for heavier fixtures.Model overview referencing SX Plus sizes

Where some wall plugs rely on simple friction without pronounced fixing blades, the SX Plus 8x40 emphasizes pre fixation of the screw and a rotation lock during installation. This design helps installers who work overhead to mount items such as fire detectors, folding shutters or bathroom equipment without losing the screw from the plug. In practice the four way expansion and expansion free neck give it an advantage in substrates that combine solid zones and perforated areas, compared with simpler plugs that may concentrate expansion forces near the surface and risk damaging tiles or thin coverings.Advantages of SX Plus design

Use Case And Overall Verdict

For professional installers and experienced DIY users working with concrete, brick and mixed masonry, the Fischer SX Plus 8x40 Expansion Plug, 100 count, offers a controlled installation process and predictable holding behavior within the 8 mm drill hole segment. Its four way expansion, rotation lock, fixing blades and expansion free neck combine to support a wide range of fixtures from lamps and TV consoles to skirting boards and mailboxes, provided appropriate wood or chipboard screws between 4.5 mm and 6.0 mm are selected for the application.Screw compatibility and applications

Within plastic masonry fixings, the SX Plus 8x40 is best suited to tasks where an 8 mm drill bit is standard and where fixtures impose moderate to high loads, while lighter applications in softer substrates can often rely on smaller plugs. Installers who value tactile feedback during tightening and secure overhead work will regard the noticeable tightening torque and screw fixation as practical benefits, though precise load values and safety margins still depend on the specific building material, hole preparation and adherence to published load tables.
