Dowel are connecting hardware elements with parallel faces used in the assembly of demountable shaft couplings. They are inserted into the grooves on the hub or shaft, where their shape binds the components and allows torque to be transferred from the shaft to the hub and vice versa. Tight dowels allow the hub to be fixed to the shaft in a fixed position, while sliding dowels are used as a guide for the hub to move along the shaft, even during rotation (e.g. gears in a gearbox).

Dowel shapes and sizes are standardised and depend on the shaft diameter. The most widely used is DIN 6885 A. In addition to high (A, B, C) and low dowels, there are also segmented dowels (semicircular), which are used in machine tools and motor vehicles and are in the shape of a circular section.

Our range includes standard dowels in C45 structural steel or stainless steel and steel bars for dowel and wedge making.
