Steel Wood Inserts
Steel wood inserts create a metal machine thread in timber and wood-based panels. Once fitted, they accept a matching bolt or machine screw, making them useful for assemblies that need to be dismantled and refitted.
They are used in furniture, cabinetry, shopfitting and joinery. Suitability for solid wood, MDF, chipboard, plywood or composite timber depends on the insert design, material thickness and expected loads.
Steel Wood Insert Styles
41/SBH Headless Wood Insert
The 41/SBH has a headless design and a hexagonal drive recess. It can be fitted within the material to minimise surface protrusion, making it useful where the mounting face needs to remain clear.

41/TBH Flush Head Wood Insert
The 41/TBH combines a flush head with a hexagonal drive recess. Select this style where its head profile and installation dimensions suit the assembly, following the specified seating requirements.

Multi-Spline Wood Insert
A multi-spline design uses external features that engage with the surrounding material to help resist rotation. Its installation method and retention performance should be checked against the product specification and the panel being used.

Why Use Steel Wood Inserts?
- Reusable machine threads: Attach components with matching bolts or machine screws.
- Convenient maintenance: Remove the attached component while leaving the insert in place.
- Less repeated wear on the timber hole: Routine assembly takes place in the metal thread rather than directly in the wood.
- A choice of profiles: Select a headless, flush-head or other suitable design to match the assembly.
Choosing the Right Insert
Check the internal thread size, insert length, head profile and installation method. Allow enough material around and beneath the insert, and consider the loads applied when the component is tightened or used.
The finished connection is only as reliable as the insert's retention in the surrounding material. Steel construction alone does not guarantee greater holding strength than a wood screw or another insert design.
For damp or exposed conditions, check the insert's finish and corrosion suitability as well as the panel material.
Installation Considerations
- Prepare the hole to the diameter and depth specified for the insert and material.
- Use the recommended driver or pressing equipment for the design.
- Keep the insert aligned during fitting and seat it to the specified position.
- Avoid excessive installation force or tightening that could damage the panel.
- Fit the matching screw or bolt, ensuring it does not bottom out or exceed the available clearance.
Make trial installations when working with a new timber or panel type. Verify retention and joint performance where loads or repeated assembly are important.
