Stair connectors for demanding constructions: The Herkules fitting set delivers maximum stability The Herkules fitting set was specially developed for use in staircase construction and stands for maximum connection strength combined with efficient installation. Whether as a reliable stair connector for spiral steps, load-bearing constructions or challenging installation situations - the set impresses with its force-fit and durable connection technology. Thanks to the combination of solid steel and precise thread technology, the set offers the exceptionally high load-bearing capacity required in staircase construction. All elements interlock perfectly, enabling a self-centring, vibration-resistant connection without additional gluing or pinning. The assembly is concealed and creates a visually calm, high-quality overall appearance - ideal for staircase constructions with architectural requirements.Summary: Application: Stair connector for spiral or straight steps Set contents: 10x ø18 mm housing with pre-assembled grub screw, 2x or 10x M10 Hercules dowels Material: galvanised steel Housing dimensions: ø18 × 30 mm Dowel size: M10 x 15 mm High contact pressure due to precise thread guidance Self-centring, no lateral displacement Concealed connection - no visible fasteners Suitable for panel thicknesses from approx. 40 mm No glue or wooden dowel connections required Easy installation even in difficult installation situations Made in Germany Connecting fitting for staircase construction: Sophisticated technology for secure connections As a connecting fitting for staircase construction, the Herkules fitting set fulfils the highest requirements in terms of mechanical strength, repeat accuracy and processing quality. The system has been designed for professional use and is particularly suitable for places where a precise fit and powerful connection are essential - for example at transitions from stair stringers to steps or for landings. The pre-assembled grub screws in the housing make installation considerably easier and ensure a reproducible result, even with series installations. In combination with the housing, the stable dowel ensures a backlash-free connection that can also withstand dynamic loads in the long term. Scheulenburg fastening system: precision and strength combined in one system The Scheulenburg fastening system is known for its uncompromising quality and intelligent design. This philosophy is perfectly realised in the Herkules system: The combination of steel housing, precision-fit dowel and grub screw forms a heavy-duty fastening system that is suitable for a wide range of applications in furniture and staircase construction. You benefit not only from the simple installation, but also from a permanently secure connection that does not give way even under continuous mechanical stress. The Herkules system therefore offers maximum flexibility - with minimum effort. Here you can find the current Scheulenburg catalogue.
