The anchor sleeve M10x80mm

The Strofix anchor sleeve is an AISI 304 stainless-steel internally threaded expansion anchor with an M10 internal thread and 80 mm length. Intended for fixing into masonry without insulation.

The anchor sleeve is inserted into a pre-drilled hole in masonry (brick, block, or stone) and accepts an M10 bolt or threaded rod. When the bolt is tightened, the sleeve expands against the sides of the drilled hole, creating a mechanical grip in the masonry substrate. This provides a secure anchor point for railing post base plates, brackets, and other structural components mounted to masonry walls and piers. The expansion mechanism is purely mechanical — no chemical anchor mortar is required. The product is specified for masonry without insulation, meaning it is installed directly into the structural masonry without passing through an insulation layer. AISI 304 stainless steel provides corrosion resistance at the masonry-steel interface.

This SKU is a single fixed configuration — M10 × 80 mm, AISI 304 only.

Use cases:

• Fixing railing post base plates to masonry walls and piers
• Anchoring railing brackets to brick or block walls without insulation
• Mounting glass canopy support brackets to masonry facades
• Securing French balcony brackets to structural masonry walls
• General M10 structural fixing into brick, block, or stone substrates

FAQ:

What substrate is this anchor sleeve designed for?

The anchor sleeve is designed for masonry — brick, block, and stone. It is not intended for concrete (use chemical anchor rods for concrete) or for masonry with external insulation (the sleeve must be installed directly into the structural masonry).

How does the expansion mechanism work?

The sleeve is inserted into a pre-drilled hole in the masonry. When an M10 bolt is threaded into the sleeve and tightened, the sleeve body expands outward against the sides of the hole, gripping the masonry mechanically. No chemical anchor mortar is required.

What are the dimensions?

The anchor sleeve has an M10 internal thread and 80 mm length. The pre-drilled hole diameter should match the sleeve's outer dimension — check the manufacturer's installation instructions for the correct drill bit size.

When should I use this instead of chemical anchoring?

Use the anchor sleeve for mechanical expansion fixing into masonry walls and piers where chemical anchoring is not required or preferred. Use chemical anchor mortar (Essve ONE or ONE-ICE) with anchor rods for concrete substrates or where higher load capacity is needed.

What about masonry with insulation?

This product is specified for masonry without insulation. If the masonry wall has an external insulation layer, the fixing must bridge through the insulation to reach the structural masonry behind — use the PVC spacer sleeve in combination with an anchor rod and chemical mortar for insulated wall assemblies.

What steel grade is used?

The anchor sleeve is AISI 304 stainless steel. AISI 304 provides corrosion resistance at the masonry-steel interface.

About Anchors & Screws

Anchors and screws are the mechanical fasteners that secure glass adaptors, canopy brackets, railing posts, French balcony holders and other architectural hardware to the building substrate. They transfer structural loads from the visible hardware into concrete, masonry, insulated façades or timber frames.

Strofix supplies 16 products in this category: steel anchors in four lengths (150, 220, 320 and 400 mm) with rod diameters of Ø16 and Ø20 mm, an anchor sleeve (M10 × 80 mm), a spacer tube (L = 100 mm), individual screws (M10 × 45), cup nuts (M10), washers, double stainless-steel threads (M8, 60 and 100 mm), a wood screw (Ø10 × 180 mm), and pre-matched screw-and-fastener sets for 1, 2, 3 or 4 glass canopy brackets — configurable for masonry without insulation, masonry with insulation and timber-frame construction.

Materials are AISI 304 stainless steel and S235 structural steel. The correct fastener depends on wall type, hardware product, bolt size and required embedment depth.
