Stair tread fastening TB Drill hole stair tread D14 x 25mm FISCHER

The fischer Stair Tread Fastener TB is a fastening solution for mounting wooden stair treads on steel stringers. The special anchor consists of an anchor sleeve made of high-quality nylon and a matching screw. When the screw is driven in, the fastener expands within the steel profile. The fastener is then glued into the wooden tread with cold glue. Marketing Claim: For fastening wooden treads to steel substructures.
