What Are Threaded Inserts For Wood?

Threaded inserts for wood are specialized fasteners designed to provide durable, strong, and reusable threaded holes in wood. These are used particularly in applications where the assembly and disassembly of a product may be required multiple times, such as in furniture or where metal screws need to be screwed into a wooden component repeatedly. Using threaded inserts helps avoid wear and tear that normally occurs in the wood from frequent screwing and unscrewing of screws directly into the wood.

As one of the leading Fastener suppliers in China, Xinchi is glad to share some key features and types of threaded inserts for wood.

Material and Construction of threaded inserts for wood:

Most threaded inserts are made from brass, stainless steel, or zinc-plated steel, providing stronger and more durable threads than the wood itself.

Types of threaded inserts for wood:

Helical Inserts (or Coil Inserts): These are essentially a coil of wire threaded on the inside and the outside. They are screwed into a pre-drilled hole in the wood. Their helical design helps distribute the load and holds the screw tightly.

Nut Inserts: These inserts are usually cylindrical with external threads and an internal threaded hole. They may have a flange at one end. They are either hammered or screwed into place and are good for heavy-duty applications.

Threaded Bushings: These are similar to nut inserts but often without a flange. They are installed by screwing them into the wood.

Expansion Inserts: These inserts have a split body that expands as a screw is driven into them, gripping the wood more securely.

Knife Thread Inserts: These have external threads that are designed to cut into the wood, creating a stronghold. They are typically screwed into place using a bolt or a special tool.

Installation of threaded inserts for wood:

The installation of threaded inserts typically involves drilling a hole of the appropriate size in the wood, then inserting the threaded insert using a specific tool or by hand, depending on the design of the insert. Some inserts require the use of an epoxy or other adhesive to secure them in place, while others are self-tapping.

Applications of threaded inserts for wood:

Threaded inserts are used in various woodworking projects, from DIY home projects to commercial and industrial applications. They are instrumental in high-stress areas where the strength of the wood might not be sufficient to hold a screw alone.

Advantages of threaded inserts for wood:

Durability: Increases the lifespan of wood components by providing a durable thread for metal screws.

Reusability: Allows for the repeated removal and reinsertion of screws without significant wear to the wood.

Strength: Enhances the load-bearing capacity of the wood.

Using threaded inserts is a practical approach in many woodworking projects to ensure the longevity and durability of assembled products, especially where disassembly or multiple assemblies are anticipated.
