KNAPP Dowel Connectors
Innovative Solutions Just For You

Dowel Connectors are the future of the woodworking industry and will one day make wooden dowels obsolete. KNAPP Connectors develops innovative connecting solutions so you don’t have to. Have you ever wondered, “why hasn’t someone invented a glue-less dowel so I can speed up my production time?” Well… we have. Wooden dowels require gluing and clamping, which slows down production time, and many times, pre-glue dowels are inconsistent in size, causing machines to jam up. Metal and plastic dowel connectors are not only consistent and durable, but they can also withstand many weather conditions. With our dowel connectors, KNAPP® uses cutting-edge technology to bring consistency, speed, and quality to your workshop.

With KNAPP, here are the 5 advantages of using our dowel connectors:
  1. Perfect alignment every time
  2. Many can be installed with or without glue
  3. Used for many outdoor applications
  4. Great for flat packed RTA designs
  5. High level of durability and consistency

KNAPP® Connectors has been serving the woodworking industry for over 30 years. Our innovative connecting systems provide the solutions that are most needed in the furniture and cabinet manufacturing industry. All our metal and plastic dowel connectors are concealed, self-tightening, and simply snap together for fast assembly. All for the benefit of reducing time, labor, and equipment cost while keeping the perfect look of your workpiece. Our German-engineered furniture connectors are specifically designed with modern craftsmen and manufacturers in mind. With numerous products to choose from and their various usages across the board, KNAPP® is confident that you will find a connecting solution that is right for you. Most all of our connecting systems are made in Austria and Germany and guarantee superior design ─ this is KNAPP®.

KNAPP® Dowel Connectors

This plastic Knapp dowel is great, it allows me to make strong connections in melamine without the need of clamping

I ordered the TUCK dowels and the Knapp plastic dowels. The TUCK metal dowel is by far stronger than the plastic one, but both work for the intended purpose.

The KNAPP®-Dowel is a strong and durable plastic dowel connector available in 6×28 mm and 8×36 mm. We make our dowels out of the best high-strength weather-resistant (POM) plastic, which gives extra durability in outdoor weather conditions. The threaded ribs are designed to tightly grip into the borehole, hence, no clamping is necessary. Unlike conventional wooden dowels, the KNAPP®️ Dowel can be used with or without adhesive. If used with the recommended KNAPP®-Adhesive PU+ (Z011/1) the lengthwise grooves and two holes ensure an optimal distribution of the glue and a firm anchoring in the material, thus creating a strong and tight connection between the components when hardened. Processing can be done is as little as 7-10 minutes after insertion when using KNAPP-Adhesive PU+

TUCK Spring Steel Compression Dowel

TUCK is a spring steel compression dowel for attaching components without glue or clamps that is immediately load-bearing. It is available in five sizes. The 6 x 25 mm, 8 x 35 mm and 10 x 32 mm dowels are processed like conventional wooden dowels. The 10 x 28 mm and 10 x 16 mm are screwed onto a component, while the other end is inserted into a borehole. 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 (furniture parts such as chair stretchers) can also be drastically increased even in smaller manufacturers.

QUICK-SET 2-Part Locking Dowel

The QUICK-SET furniture connector is a simple and efficient 2-part Locking Dowel connector that includes a threaded stud and a plastic sleeve. It is self-tightening, non-visible, and can be inserted immediately into standard boreholes without the need for glue. Cabinets and closet systems can be put together on-site quickly and easily, thus high transport costs are omitted. The processing of the two-piece connector is the same as with a conventional dowel but in a much shorter time, as glue drying time is not a factor. In addition to its main area of application as a modern cabinet connector, the QUICK-SET can also be used for dresser drawer boxes, bedroom shelving, bookcases and more.

KNAPP® Adhesive PU+

Our KNAPP® Adhesive PU+ is the last one-component polyurethane based adhesive that you’ll need. For a permanent and reliable hold, we recommend using something that will last! It is water resistance Class D4 according to EN 204, and is 100% formaldehyde free. With its resealable cap, you can use it anytime without wasting the tube.


The KNAPP® Adhesive PU+ is commonly used with our KNAPP Plastic Dowel. Once the glue is applied and the components are joined, processing can be done is as little as 7-10 minutes. This drastically increases the production time compared to standard dowels and wood glue.
