TUCK Compression Dowel – Sample Pack

The TUCK is a spring steel compression dowel that is immediately load-bearing for attaching components without glue or clamps. TUCK is available in five sizes (Ø 6 mm x 25 mm, Ø 8 mm x 35 mm, Ø 10 mm x 32 mm, Ø 10 mm x 28 mm and Ø 10 mm x 16 mm) and is processed like a conventional wooden dowel. The TUCK is self-tightening and no clamping aid or glue is required when assembling the workpiece (cabinet, furniture, interior design, etc.). The spring steel design guarantees permanent tightening by pushing against the borehole wall. The processing can be done with a dowel-boring machine or CNC. Due to eliminating usual clamping aids, the productivity of the gluing of workpieces (cabinets) can also be drastically increased even in smaller manufacturers. Also in industrial furniture manufacturing, the production time per workpiece can be considerably reduced.

(View and Download Instruction Manual)


  1. Drill borehole according to the TUCK dowel size
  2. Insert the dowel into the surface (not into the edge) of the workpieces
  3. Brush the edges with glue (optional) and attach workpiece with a rubber mallet

*Note – Assemble components with a rubber mallet on the surface, but not necessarily from above against a hard surface; it is better to hit the surface from below and use the self-suspension of the material – this way the parts connect very fast. In the case of very large workpieces, a clamping aid might be needed. If glue is used it is not necessary to wait for the complete hardening of the glue. Once the desired end position has been reached, the clamping aid can be removed immediately.
