Wall plug Fischer 535462 screw anchor 50 pcs 25 mm

The Fischer 535462 screw anchor is a polymer wall plug designed for secure fixing in solid masonry such as brick and concrete. Each plug is 25 mm long and is intended for use with a 5 mm drill bit, requiring a minimum hole depth of 40 mm. Supplied in a pack of 50 pieces, these wall plugs deliver consistent expansion and reliable holding power for a range of light-to-medium duty fastening tasks.

Advantages

Fischer wall plugs are manufactured to maintain consistent geometry and expansion behaviour, providing stable load distribution in masonry substrates. The 25 mm length combined with the 5 mm drill diameter allows for simple installation while minimising the required drill effort. The pack of 50 ensures enough anchors for multiple installations and reduces frequent repurchasing. Materials and design help resist pull-out and tilting of attached objects when installed according to guidelines.

Suitable for

• Fixing light shelving and small cabinets to brick or concrete walls
• Mounting picture rails, hooks and towel rails
• Securing electrical boxes, conduit clips and cable trunking
• Attaching sanitary fittings and bathroom accessories to solid masonry

Key specifications

• Anchor type: expansion screw anchor (polymer wall plug)
• Quantity: 50 pieces per pack
• Length: 25 mm
• Required drill diameter: 5 mm
• Minimum drill hole depth: 40 mm
• Intended substrate: solid masonry (brick, concrete)

How to use

Drill a clean hole in the masonry using a 5 mm bit to a depth of at least 40 mm, removing dust from the hole before inserting the plug. Insert the Fischer screw anchor flush with the surface, then drive an appropriate screw into the plug until the plug expands and grips the substrate. Tighten the screw progressively—do not overtighten—to avoid deforming the plug or damaging the wall. For hollow or weak substrates, select a fixing system designed for those conditions rather than this solid-masonry anchor.

Usage recommendations

Use screws with an external thread diameter suitable for 5 mm plugs (check screw manufacturer guidance). Always verify substrate condition before installation and, where safety or high loads are involved, follow applicable load tables and installation manuals for spacing, edge distances and load ratings.
