Screw anchor / wall plug, Fischertechnik 532735, pack of 6, size 6 mm

Fischertechnik screw anchors / wall plugs 532735, pack of 6, are expansion plugs designed for fastening screws and threaded rods in masonry and concrete. Each anchor has a 6 mm nominal size and is intended for medium-duty loads where a compact brass fixing provides reliable anchoring. The design uses an internal cone that expands the sleeve inside a pre-drilled hole as the screw or threaded rod is turned, creating a mechanical hold against the hole wall. These anchors are suitable for mounting small fixtures and components in model construction, securing control boxes or shelves, and general repair tasks that require compact anchors and conventional metric fasteners.

Advantages

The brass sleeve and internal brass cone provide secure expansion and metal-to-metal contact for stable anchoring in solid building materials. The compact design reduces drill hole size and installation time compared with larger anchors. A non-slip surface structure prevents rotation of the anchor during setting, and the product accepts standard screws and threaded rods, offering flexibility in fastener choice. Surface-flush removal is possible if required.

Suitable for

• Mounting small fixtures and components in model construction
• Fixing control boxes and small electrical enclosures
• Attaching lightweight shelves and brackets in masonry or concrete
• General repair and maintenance tasks requiring compact anchors

Key specifications

• Anchor type: expansion plug with internal brass cone and brass sleeve
• Material: brass components for sleeve and cone
• Nominal size: 6 mm
• Pack quantity: 6 pieces
• Suitable base materials: masonry and concrete (solid building materials)

How to use

Drill a hole in the base material to the required diameter and depth for a 6 mm expansion anchor. Insert the anchor into the pre-positioned hole until it is flush with the surface or positioned as needed. Place a compatible metric screw or threaded rod into the anchor and rotate to tighten; as the screw or rod is turned, the internal brass cone expands the sleeve and anchors against the hole wall. If surface-flush removal is required, unscrew and extract the anchor according to the installer’s practice for brass expansion fittings.

Usage recommendations

Use appropriate drill bit and drilling technique for solid masonry or concrete. Verify that the chosen screw or threaded rod matches the anchor’s nominal size and is suitable for the intended load. Ensure hole depth and cleanliness before inserting the anchor and avoid using the anchor in hollow or unsuitable base materials.
