What Are Furniture Fasteners and Fixings?
Furniture fasteners are metal fixings used to join furniture components together or to provide a threaded insert within wood. They allow bolts and threaded fittings to be securely tightened into timber, offering strength and stability where repeated assembly or load-bearing support is required.
In upholstery applications, fasteners are commonly used where furniture legs, castors or structural components need to be attached firmly to wooden frames without damaging the surrounding material.
Types of Upholstery & Furniture Fasteners
T-Nuts (Tee Nuts)
T-nuts are a popular type of furniture fastener, particularly for securing furniture legs and bases. They feature a threaded centre with prongs that embed into the wood, preventing rotation once installed.
T-nuts are commonly used for:
- Sofa and chair leg fixings
- Bed and table leg attachments
- Furniture frames requiring a strong, flush fixing
Available in M8 sizes, T-nuts are ideal where a secure, load-bearing fixing is required within timber.
Insert Nuts (D-Nuts)
Insert nuts, often referred to as D-nuts, are threaded metal inserts designed to be fitted into pre-drilled holes in wood. They create a permanent internal thread, allowing bolts to be securely tightened and removed when needed.
Insert nuts are commonly used for:
- Flat-pack furniture assembly
- Furniture repair and refurbishment
- Applications where repeated assembly is required
D-nuts provide a clean, strong fixing point and are widely used in furniture manufacturing and upholstery workshops.

Furniture Fixings & Fasteners FAQs
How to install T-nuts and insert D-nuts correctly?
T-nuts are usually fitted by drilling a hole through the timber and tapping the pronged face into the wood from the reverse side so it sits flush. Insert nuts are installed into a pre-drilled hole and tightened or pressed into place to create a secure internal thread. Correct hole size and alignment are important to achieve a strong fixing.
Can furniture fasteners be reused once fitted?
T-nuts can often be reused if they remain firmly seated in the timber, although they may loosen if removed repeatedly. Insert nuts are designed to be more permanent and can generally be reused without affecting the strength of the fixing.
Will furniture fasteners work in MDF or chipboard?
Furniture fasteners can be used in MDF and chipboard, but care should be taken when drilling and fitting. In softer or engineered materials, insert nuts are often preferred as they provide better grip and reduce the risk of the fixing pulling out over time.
Can these fasteners be used with castors or wheels?
Yes, furniture fasteners are commonly used to fix castors or wheels to wooden furniture frames, provided the thread size and fixing depth are compatible with the castor fitting.
Are these fasteners suitable for commercial furniture use?
Yes, these fasteners are commonly used in commercial and contract furniture where strength, durability and repeat assembly are required, including seating, hospitality furniture and public-use furnishings.
