Product description
Fischer TB sold individually – single fixing for a wooden stair tread on a steel profile
If you are repairing a single stair tread, completing an existing installation or only need a few fixing points, there is no need to purchase a full box. This offer includes 1 complete Fischer TB fixing designed for mounting a wooden stair tread on a steel profile.
This is a single piece taken from the original fischer article 60580 factory pack containing 50 pieces. The 1-piece sales unit does not have its own manufacturer EAN.
When is it worth buying Fischer TB individually?
Buying individual pieces is practical for stair repairs, replacing a single fixing, service work and small installation jobs where a full pack of 50 pieces would not be necessary.
If you are installing a complete staircase or need a larger number of identical fixing points, a separate offer for the full factory box of 50 pieces is also available.
What substrate is the TB fixing designed for?
Fischer TB is designed for steel profiles. The system is intended for fixing wooden stair treads and wooden boards thicker than 30 mm to steel stair structures.
The TB variant should not be confused with Fischer TBB. TBB is intended for concrete and other solid building materials, whereas TB has been developed specifically for steel profiles.
Why is Fischer TB suitable for steel structures?
The fixing has a short expansion zone, so it requires only a small amount of space inside the profile. This allows it to be used even in relatively narrow steel profiles.
The flexible geometry of the nylon plug absorbs vibrations and helps reduce squeaking noises from wooden stair treads during use.
How does a single Fischer TB fixing work?
After inserting the fixing into the prepared hole in the steel profile, tightening the screw causes the nylon plug to expand. This creates a mechanical fixing between the stair tread and the steel structure.
Fischer states that optimum fixing performance is achieved with the additional use of a cold-setting wood adhesive, selected appropriately for the particular structure and installation conditions.
What holes should be prepared?
A 14 × 25 mm hole should be prepared in the wooden stair tread. A hole with a diameter of 9 mm is required in the side of the steel profile.
The fixing uses a 5.0 × 40 mm screw. The manufacturer also specifies a 15 mm wrench size.

TB or TBB?
The choice depends primarily on the stair structure. TB is used for steel profiles. If the wooden stair tread is to be fixed to concrete or another solid building material, the appropriate solution is the TBB variant.
