mk Assembly Components

Our connection technology is versatile and gives you complete freedom in the design of your construction. Any angle desired can be realized. All assembly components use standard screws. You can choose from angle connections, console connections, tension connections, conecting plates, corner connections, truss joints or clamps. With this selection we always offer you the optimal connection technology depending on the requirements.

Additional Information on Assembly Components


mk Nut 1
mk Nuts Overview

Nuts are the preferred mounting elements at mk in conjunction with angles, consoles, plates and T-slot accessory components. They are to be inserted into the profile on the front and can be used anywhere the installation situation allows because of their high load capacity and tear-out strength.

  • Drop-in nuts are intended for later insertion in the profile slot e.g. if the front of the profile is already closed and the Nuts 1 can no longer be inserted.
  • Nuts and drop-in nuts with spring steel sheet are fixed in the profile slot and can no longer slide. The assembly of attachment elements vertically is much easier.
  • Nuts with additional ESD function penetrate the anodized coating of the profile and thus ensure the conductivity of the connection.
  • Nut 1 and drop-in nut 1 with spring steel sheet are also available in stainless steel and thus corrosion-resistant.

Angle Connections and Console Connections

At mk our standard connection is the solid angle connection. The angles are fastened with DIN socket head screws, Schnorr ribbed washers, and T-nuts, which we refer to as nuts. For statically highly stressed constructions, in addition cast consoles are used in the series 50 and 60.

Advantages Of The Angle Connection

  • Stable connection without end processing
  • Easy to dismount and reuse retrospectively
  • Locking connection for keyed angles
  • Tolerance compensation possible
  • Lateral bore channels for accommodating panels

Tension connections

If the grooves of the profiles, e.g. for introducing panels, should remain free, use our tension connections. A construction with tension connections is visually appealing, interference contours due to angles do not occur. Various tension plugs are available for series 25, 40, and 50.

Advantages of the Tension Connection

  • Visually inconspicuous connection possibility
  • System grooves of the profiles remain free
  • No interference contours
  • In some cases the position can be moved retrospectively
  • Optimal for constructions with clean room profiles

Connecting Plates

With the aid of connecting plates, profiles can easily be integrated retrospectively in an existing construction. Depending on the attachment situation, choose from straight plates, T-plates, or angle plates. A lightweight version and a heavy version are available dependant on load.

Advantages of the Connecting Plates

  • Easy retroactive assembly
  • Mechanical processing is not required
  • Optimal for reinforcement of a connection
  • No interference contours in the interior of a construction
  • Locking element thanks to keyed plates

Corner Connections

Corner connections in the form of corner nodes offer an attractive possibility of interconnecting profiles on the face side. The grooves of the profiles remain free and the corner point is convincing through seamless transitions, even for edge profiles and semi-circular profiles. The corner nodes are fastened either with screws that are screwed into the thread of the face side bore channels or via a tension connection.

Advantages of the Corner Connection

  • High stability through solid aluminum material
  • Attractive design
  • System grooves of the profiles remain free
  • Versions for edge profiles and semi-circular profiles available
  • Optimal for constructions with clean room profiles

Truss Joints

Truss joints are realized with the aid of truss blocks that have a specific angle of 30°, 45° or 60°. Consequently the transverse profile does not need to be mitered. Truss constructions are used to bridge large distances involving high loads, and to brace support frames and frame constructions.

Advantages of the Truss Joints

  • High loads can be carried
  • Profiles do not need a miter cut
  • Bracing of frames is quickly and easily possible
  • Suitable for linear axis portals with large span widths


With clamps without key, profiles can be quickly connected together in any angle desired without high material costs. Clamps with key ensure a right-angle connection of the profiles. An opposing arrangement of the clamps prevents the profiles from twisting.

Advantages of the clamps

  • Low material costs
  • It is assembled quickly and easily retrospectively
  • Variable placement
  • Free selection of the angle
