Threaded sockets - The optimum solution for stable and resilient connections


Threaded sockets are indispensable connecting elements when it comes to creating a secure and resilient connection in wood, metal or plastic. They ensure a high level of stability and durability, particularly in furniture construction and wooden joints. Thanks to their self-tapping external thread, they can be easily and precisely screwed into the workpiece and provide a reliable basis for metric screws.

The versatility of the threaded sockets makes them a favourite choice for craftsmen and industrial companies. Whether for furniture joints, exhibition stand construction or interior fittings - they enable a removable yet secure screw connection. Thanks to their special design with internal and external threads, they can also be used several times without losing their grip.


  • Material: High-quality galvanised steel or brass for optimum corrosion resistance
  • Thread sizes: Available in M4, M5, M6, M8, M10 and M12
  • Lengths: Between 8 mm and 25 mm depending on thread size
  • Drive types: Hexagon socket or slot for easy installation
  • Areas of application: Furniture construction, wood processing, interior fittings, exhibition stand construction
  • Assembly: Direct screwing in without adhesive or additional fastening material

Screw-in nut - perfect for permanent and removable wood connections


A wood screw-in nut is a special type of threaded socket that is primarily used in wood and wood-based materials. Its advantage lies in its particularly easy installation: thanks to the self-tapping external thread, it digs securely into the material when screwed in and provides a long-lasting anchoring for metric screws or threaded bolts.

This type of socket is ideal for applications where a stable but also removable connection is required. Pieces of furniture that need to be assembled and disassembled frequently benefit particularly from this technology. Thanks to the different sizes and materials available, screw-in nuts can be used for a wide variety of wood types and requirements.


Screw-in sleeve - strong connection for wood and furniture construction


The screw-in sleeve is characterised by its simple processing and enormous stability. It ensures a secure connection, particularly in constructions made of solid wood, MDF or chipboard, and prevents the material from wearing out or being damaged by repeated screwing in of screws.

As the screw-in sockets are available in various materials - from galvanised steel to brass and stainless steel - they are also suitable for applications that require particularly high corrosion resistance. Furniture or wood panelling that is exposed to moisture, for example, benefits from galvanised screw-in sockets, which remain rust-free and are permanently stable.

Another advantage of the screw-in sleeve is the even load distribution: while simple wood screws often loosen over time, the screw-in sleeve remains securely anchored and ensures a permanently stable connection.


Wood screw nut - Durable connections for demanding constructions


The screw nut for wood is the ideal choice for anyone who needs a stable yet removable connection in wood-based materials. Whether for furniture, interior fittings or timber constructions - these special nuts ensure that screws and threaded bolts are held securely in place. They are easy to screw in and provide a durable basis for various fastenings.

Thanks to their special design, they are frequently used in industrial applications and in professional trades. Furniture manufacturers use them just as much as carpenters and interior fitters to create connections that remain stable even after frequent loosening and tightening of the screws.


How do you install threaded sockets correctly?


The installation of threaded sockets is straightforward and only requires a few steps:

  1. Pre-drill the workpiece with a suitable drill. The diameter of the drill hole should match the socket exactly.
  2. Slowly screw in the threaded socket using a hexagon socket spanner or a suitable screwing tool. Make sure that the socket is straight.
  3. Once fully screwed in, the socket is ready for use and can be fitted with a metric screw.

Conclusion: Why threaded sockets, screw-in nuts and screw-in sockets are indispensable


Whether in furniture construction, woodworking or for industrial applications - threaded sockets, screw-in nuts and screw-in sockets offer an unbeatable combination of stability, easy assembly and reusability. They enable secure connections that can be loosened and reassembled at any time without damaging the wood structure.

Thanks to the high-quality materials and precise manufacturing, these connecting elements offer a permanently reliable solution for a wide variety of constructions. They facilitate the assembly of furniture, ensure resilient connections in wooden structures and are therefore an essential choice for professional and craft applications.
