FM Products Red 5.5mm Premium Expansion Plugs

FM Products Red 5.5mm Premium Expansion Plugs are high‑quality nylon wall plugs designed
for secure, reliable fixing in solid substrates. Colour‑coded red and sized for 5.5mm
drill holes, they provide strong expansion and grip for screwing into brick, block,
stone and concrete in everyday installation work.

FM Products Red 5.5mm Premium Expansion Plugs provide a dependable anchor point for screws
in solid masonry substrates. Manufactured from high‑grade nylon, they resist splitting,
ageing and creep under load, delivering a long‑lasting fixing for brackets, clips,
battens, electrical accessories and general hardware.

The plug’s expansion zones are designed to spread load along the drilled hole when the
screw is tightened, helping to maximise grip and reduce the risk of plug spinning. The
red colour makes them easy to distinguish from other plug sizes in mixed fixings boxes
and on site.

Ideal for tradespeople and DIY users alike, these premium 5.5mm plugs are widely used in
domestic, commercial and light industrial applications for day‑to‑day fixing tasks into
brick, block and concrete.

Typical Use Cases

• Fixing pipe clips, conduit saddles and cable trays to masonry.
• Mounting brackets, clips and small shelving supports.
• Securing electrical back boxes, trunking and accessories (where suitable).
• Fixing battens, rails and light timber sections to walls.
• General light‑to‑medium duty wall fixings in brick, block and concrete.

Installation & Usage Tips

• Use correct drill size: Drill a 5.5mm diameter hole (or as stated on the pack) to the required depth.
• Clean the hole: Remove dust and debris to improve plug grip.
• Flush insertion: Push the plug fully into the hole until it is flush with or just below the surface.
• Match screw size: Use the screw gauge/diameter range recommended on the packaging for best performance.
• Avoid overtightening: Tighten the screw until firm; over‑driving can strip the plug or damage the substrate.
