Description
5/16" Thread T-Nut Insert – 10mm for Timber Furniture & Fixings
This 5/16″ thread x 10mm long T-Nut is a practical threaded insert designed for use in timber furniture and general woodworking applications. Finished in zinc plating for corrosion resistance, it provides a durable internal thread that allows bolts to be tightened securely without damaging the timber.
The 4 prong construction helps anchor the insert firmly into place, reducing the risk of movement or pull-out once installed. While widely used in furniture repairs, it is equally suitable for cabinetry, joinery, and various workshop or manufacturing uses.
Common Applications in Furniture and Timber Projects
This size T-Nut is often used for fixing chair legs, smaller sofa feet, castors, and mounting hardware within timber frames. It’s a popular choice where a slightly smaller thread is required compared to 3/8″ fittings.
Outside of furniture, these inserts are also used in cabinetry, timber fabrication, and general DIY builds where a reliable threaded fixing point is needed in wood.
Installation Guide and Size Considerations
The T-Nut features a 10mm barrel length and is suited for 5/16″ thread bolts. Installation typically requires a hole between 10mm and 12mm in diameter, with a minimum timber thickness of 10mm for proper seating.
The four prongs are designed to embed into the timber when tapped into place, helping to prevent rotation when tightening bolts. Installation is usually done from the rear or inside of the timber panel to achieve the best hold.
We also carry alternative sizes, including 3/8″ thread options and a longer 5/16″ x 17.5mm version for deeper timber applications. If you’re unsure which size is right, our team is happy to assist.

Installing a T-Nut in Timber Furniture
This T-Nut provides a simple way to create a strong threaded fixing point in timber furniture. It is commonly used when fitting chair legs, sofa feet, castors, and internal mounting hardware.
Before starting, take a photo of the existing setup so you can refer back during reassembly. When handling heavy furniture, always use safe lifting techniques and ask for assistance if required.
Tools Required
- 5/16″ x 10mm T-Nut
- Drill with 10–12mm drill bit
- Hammer or rubber mallet
- Matching 5/16″ bolt or furniture fitting
Step 1: Prepare the Area
Position the furniture so you can safely access the timber frame. Remove any existing hardware and clean the area.
Step 2: Check or Drill the Hole
Ensure the hole is between 10mm and 12mm wide and deep enough for the insert. Drill if necessary.
Step 3: Position the T-Nut
Insert the T-Nut into the hole from the rear side, ensuring the prongs sit flush against the timber surface.
Step 4: Secure in Place
Tap the T-Nut gently with a hammer or mallet so the prongs embed into the wood.
Step 5: Tighten the Bolt
Thread the bolt or furniture leg into the insert and tighten to fully seat the T-Nut. Avoid overtightening.
