Fischer SX Plus 8x40 Expansion Plug 100 Pack - Four-Way Nylon Anchor For Solid Masonry

Fischer SX Plus 8x40 Expansion Plug 100 Pack uses a four-way expansion design with an 8 mm drill diameter and 40 mm anchor length for secure fixings in concrete and brick. For installers and DIY users, the high tightening torque and nylon body matter most.

Fischer SX Plus 8x40 Expansion Plug 100 Pack is a nylon wall anchor designed for high holding power in solid masonry, combining a four-way expansion body with fixing blades that lock the screw in place, especially useful for overhead installations.

Design, Dimensions And Materials

At the core of the SX Plus concept is a four-way expansion geometry that spreads load into the base material when the screw is tightened, increasing holding values in concrete, sand-lime brick and general masonry compared with simpler two-way plugs.Four-way expansion body The plug body is molded from high-quality nylon to provide a durable, creep-resistant anchor that maintains clamping force over time in a range of solid and perforated building materials.Nylon plug material

For this 8x40 format, Fischer specifies a drill diameter of 8 mm and a minimum drill hole depth of 50 mm, giving the plug enough room to seat fully and expand along its 40 mm anchor length.8 mm drill diameter and 40 mm length Compatible wood and chipboard screws are listed with diameters from 4.5 mm to 6.0 mm, which match common metric and imperial screw sizes used for light fixtures, cabinets and brackets.4.5-6.0 mm screw compatibility

Holding Behavior And Installation Features

The SX Plus 8x40 is designed for both pre-positioned and push-through installation, so installers can insert the plug before or through the fixture depending on layout and access.Pre-positioned and push-through installation When the plug is driven into the hole, integrated fixing blades fold inward, capturing the screw so it does not fall out as it is started, a detail particularly valuable for overhead work on ceilings and high walls.Fixing blades for screw pre-fixation

A pronounced plug edge at the mouth of the anchor stops it from slipping deeper into the drill hole, which helps keep the fixture snug against the wall and simplifies alignment.Plug edge to prevent slipping A rotation lock built into the body prevents the anchor from spinning when the screw is tightened, and the geometry of the nylon shell yields a noticeable tightening torque that signals when the screw is properly seated without overdriving it.Rotation lock and tightening feel

Applications And Compatible Building Materials

In practice, Fischer positions the SX Plus line as a specialist for solid building materials, citing concrete, solid brick and solid sand-lime brick as core substrates where the four-way expansion achieves high load values.Concrete and solid brick compatibility The same plug can be used in perforated bricks and perforated sand-lime bricks, as well as aerated concrete, allowing one 8x40 anchor type to cover a wide mix of residential and light commercial wall structures.Perforated masonry and aerated concrete

Typical fixtures listed for SX Plus anchors include lamps, wardrobes, motion detectors, skirting boards, light wall shelves, mirror cabinets, mailboxes, TV consoles, trellis elements, folding shutters, bathroom and WC accessories and fire detectors.Application examples For installers working across different wall types, using a single 8 mm drill bit and the same 40 mm plug simplifies kit logistics, while the nylon composition keeps the anchor suitable for indoor use in living spaces where fixtures may be repositioned over time.

Pack Size, Identification And Market Context

The expansion plug covered in this article is the Fischer SX Plus 8x40 100 Pack, identified by article number 568008 and GTIN 4048962480832, supplied in a folding box with 100 individual nylon anchors.Art.-No. 568008 and 100-piece box Fischer also produces larger bulk formats, including a 1,200-piece SX Plus 8x40 pack in a bucket under article number 567899, which shares the same 8 mm drill diameter, 50 mm minimum drill hole depth and 40 mm plug length but targets high-volume users such as contractors and workshops.SX Plus 8x40 1200-piece bucket

Compared with simpler plastic plugs that offer two-way expansion and lack fixing blades, the SX Plus 8x40 is engineered for more demanding applications in solid masonry, where higher load capacity and predictable tightening behavior reduce callbacks. In the broader nylon plug category, its 8 mm drill diameter and 40 mm length place it in an intermediate size range suitable for mid-weight fixtures rather than very light pictures or heavy structural elements, making it a practical option for residential and light commercial fit-out tasks.

Use Case Placement And Comparison

For US-based contractors and experienced DIY users, Fischer SX Plus 8x40 Expansion Plug 100 Pack fits as a mid-size nylon anchor when a single plug type must cover concrete, brick and perforated masonry with consistent drilling and screw specifications. The requirement for an 8 mm drill diameter and 50 mm minimum hole depth is typical for this size class, so users with standard hammer drills and masonry bits face no unusual tooling demands.Minimum 50 mm depth requirement Against lower-cost generic 8x40 plugs that may not specify compatible screw diameters or tightening torque characteristics, the SX Plus adds defined 4.5-6.0 mm screw compatibility and a designed rotation lock, an advantage when fixtures must be installed repeatedly or removed and reinstalled without damaging the anchor.

Overall, SX Plus 8x40 suits users who routinely mount lamps, shelving, bath accessories or electronics brackets onto solid walls and want a single, documented plug system rather than mixing different anchors per job. Its limits appear at the extremes: lighter fixtures could use smaller plugs for reduced drilling effort, while very heavy loads or safety-critical installations may call for larger anchors or mechanical fixings. Within the mainstream nylon plug segment, the combination of four-way expansion, overhead-friendly fixing blades and a standardized 8x40 format gives Fischer SX Plus a clear role as a dependable everyday anchor for solid masonry work.
