Threaded inserts for wood, also known as wooden thread inserts or threaded wood inserts, are specialised fasteners designed to create durable, reusable metal threads in wooden substrates. These thread inserts provide a robust solution for fastening in materials such as softwoods, hardwoods, MDF, and plywood. By offering strong internal threads, they significantly enhance the strength and lifespan of bolted joints in woodworking applications.
Commonly found in furniture manufacturing, cabinetry, and wood assembly, threaded inserts for wood allow M6 or M8 bolts and machine screws to be installed and removed repeatedly without damaging the wooden base material.
Threaded wood inserts are installed by driving them into pre-drilled holes using tools such as Metric Hexagon Socket Key Wrenches or Hex Drive Bits. As the insert is screwed in, its self-tapping external threads cut into the wood, securing a firm mechanical grip.
Once fitted, these inserts offer an internal machine thread that accommodates corresponding fasteners, enabling secure and repeatable assembly. Options are available with or without a flange to suit different load distribution needs or for flush mounting in wood.
Accu's range of threaded inserts for wood are manufactured from zinc alloy, a material chosen for its excellent balance of strength, machinability and corrosion resistance. These characteristics make it ideal for forming durable internal threads in wooden substrates such as softwoods, hardwoods, MDF and plywood.
A: Threaded inserts are installed by drilling a pilot hole smaller than the OD of your selected insert, then using a hex key or insert installation tool to screw the insert into the wood. The self-tapping threads cut into the wood as it is driven in.
A: They provide strong, reusable metal threads in wooden materials, allowing for secure fastening and repeated assembly without wear or damage to the wood.
A: Yes, they are effective in plywood, especially when care is taken to drill accurately and avoid splitting. Using inserts with longer lengths can help improve grip in layered materials.
A: Yes, threaded wood inserts can be used in MDF. Pre-drilling to the correct size is important, and using inserts designed for soft or composite materials helps ensure a strong hold.
