Fields of use for the concealed screw assembly

Joining

Concealed screw assemblies are not only ex-

cellent suited for the construction of cabinets and

shelves, but also provide precise and durable

joints in making frames.

Repair

Only two work steps are needed to join a broken

cabinet corner firmly back together. The cabinet

does not even have to be taken apart for this re-

pair, which takes only five minutes.

Reinforcing

A drawer that “wobbles” at the corners can

be reattached in just a few minutes, with just

two little tricks. It doesn‘t even have to be

taken apart to do it.

The principle of this rapid, exact and highly durable joint is a diagonally drilled

blind hole (pocket hole). In order to be able to make this hole precisely and

without the drill going astray, a drill guide is used with a stepped drill design. The

tip of the drill makes a small guide hole for the screw thread, while the second step

of the drill makes a larger hole for sinking the screw head in the wood. The great

advantage over a normal screw assembly is that in this way, the screws are not

visible from outside.
