Idea and system

Simply a brilliant invention

The dovetail shape is a classic feature for precision and quality, both in mechanical engineering and in the wood processing industry.

This principle makes the use of the Hoffmann Key unique. Due to the extremely precise, double dovetail shape of the Key and its serrated sides, it is always a snug fit and a positive guide when driven into the routered slots. This draws the two parts to be joined, accurately and permanently together.

Whether in industrial use or for trade use: Hoffmann keys are generally easily to use and efficient, not only for single pieces but also in volume production. The work-pieces are held together durably, due to the two dovetail-shaped sides which have ribs on the internal sloping surfaces. Firm contact is made in the wood and therefore they grip tightly and keep the parts securely together, preventing any slide or movement of the parts.

NEW: W0 - the smallest Hoffmann Key.
