## Long description

The Fischer Stair-tread fixing TBB is an expansion anchor system for attaching wooden stair treads to concrete staircase stringers. The system includes a high-quality nylon fixing sleeve and a matching screw; when the screw is driven in, the anchor expands in the concrete and is then bonded into the wooden tread using cold wood glue. The product is supplied in packs of 50 and is designed for reliable stair-tread installation in concrete sub-constructions.
Advantages
The nylon sleeve and metal screw combination provides secure expansion in concrete while minimizing splitting in the wood. The fixing is suitable for repeated and consistent installation thanks to standard drill and screw dimensions (drill hole Ø 1.4 cm, minimum screw Ø 5.5 mm). Packs of 50 pieces and a screw length of 7 cm allow efficient work on stair projects.
Suitable for
Mounting wooden stair treads to concrete stringers
Internal stairs in residential and commercial buildings
New builds and staircase renovations where concrete sub-construction is present
Key specifications

Product: Stair-tread fixing TBB (expansion anchor)
Drill hole diameter: 1.4 cm
Minimum screw diameter: 5.5 mm

How to use
Drill the specified Ø 1.4 cm hole into the concrete stringer, insert the nylon fixing sleeve, place the wooden tread accurately, and drive the matching screw through the tread into the sleeve. As the screw is tightened, the sleeve expands in the concrete to secure the anchor. After mechanical fixation, apply cold wood glue into the predrilled hole or onto the screw/sleeve interface and allow the adhesive to cure to bond the fixing into the wooden tread.
Usage recommendations
Use cold wood glue designed for structural wood joints and follow the adhesive manufacturer's curing times. Pre-check drill depth and alignment before final tightening. For safety and durability, ensure the concrete substrate is sound and free of loose material; do not exceed the recommended drill diameter or use undersized screws.
