These metal threaded bushings with internal metric thread are installed into a pre-drilled hole in wood, creating a wear-resistant and reusable thread suitable for repeated assembly and disassembly.
Applications for joineries, cabinet makers and interior fit-out companies
Screw-in wood inserts are ideally suited for:
– Furniture manufacturing with removable components
– Custom interior fit-out and cabinetry
– Wooden frames and lightweight structural assemblies
– Modular interior systems and panel constructions
– Professional joinery projects requiring serviceability or reassembly
By introducing a metal thread into wooden components, the risk of thread wear, fibre pull-out or loosening over time is significantly reduced, increasing the structural reliability and lifespan of professional wood assemblies.
Materials and finishes
The box-type screw-in inserts for wood are available in the following materials:
– Brass – excellent corrosion resistance
– Steel white zinc plated – high mechanical strength for general-purpose applications
– Stainless steel AISI 303 – corrosion-resistant solution for humid environments or intensive use
These material options make the inserts suitable for a wide range of interior woodworking, furniture production and professional fit-out applications.
Installation guidelines and best practices
For optimal performance in wood:
-
Accurate pre-drilling – select a drill diameter matching the external thread to ensure strong anchoring without splitting the wood
-
Controlled installation – screw the insert into the wood using the appropriate tool (hex key or screwdriver, depending on the version) until flush
-
Final fastening – install the bolt or threaded rod into the internal metric thread to obtain a secure and repeatable connection
Correct drilling and alignment are essential to achieve maximum load capacity and consistent performance, especially in applications involving repeated assembly.
Limitations and alternative solutions
These box-type screw-in inserts perform best in softwood and medium-density hardwoods.
For exotic hardwoods, we suggest the self-tapping slotted inserts. In HPL or compact laminate, self-tapping inserts with 3 cutting holes are recommended to ensure proper installation and holding strength.
