Product description
Fischer TB 60580 – fixing for wooden stair treads on steel profiles 50 pieces
Fischer TB is a special fixing designed for installing wooden stair treads on steel stair structures. The system consists of a high-quality nylon plug and a suitable screw. During installation, the plug expands inside the steel profile and creates a mechanical fixing for the stair tread.
This offer includes one complete factory box of Fischer TB article 60580 containing 50 pieces.
What is Fischer TB used for?
The TB variant is designed specifically for fixing wooden stair treads and wooden boards thicker than 30 mm to steel profiles. It should not be confused with the TBB variant, which is intended for concrete and other solid building materials.
The short expansion zone requires little space inside the profile, allowing the TB system to be used even with relatively narrow steel profiles. The flexible geometry of the fixing absorbs vibrations and helps reduce stair squeaking during use.
Key benefits of Fischer TB
- special fixing for wooden stair treads on steel structures,
- suitable for steel profiles,
- short expansion zone suitable even for narrow profiles,
- high-quality nylon plug,
- flexible geometry that absorbs vibrations,
- helps reduce squeaking of wooden stair treads,
- designed for stair treads and wooden boards thicker than 30 mm,

How does Fischer TB work?
After the fixing has been inserted into the correctly prepared hole in the steel profile, tightening the screw causes the nylon plug to expand. This creates a stable mechanical anchorage inside the profile.
Fischer states that the system achieves optimum fixing performance when used together with a cold-setting wood adhesive. After mechanical fixing, the stair tread may therefore be additionally bonded according to the installation method suitable for the specific structure.
How should the holes for TB 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.
Variant TB 60580 uses a 5.0 × 40 mm screw. The manufacturer specifies a 15 mm wrench size.

TB or TBB – which variant should you choose?
Fischer TB is intended for fixing wooden stair treads to steel profiles. If the stair tread is to be fixed to concrete or another solid building material, the appropriate Fischer TBB variant should be used.
Choosing the correct variant is important because TB and TBB differ in fixing design, required hole dimensions and intended substrate.
