Tee Nut

Tee nuts are the clean, low-profile way to lock threads in wood, plywood, and composite panels while keeping the finished face pristine. Our tee nuts bite from the blind side, building a secure anchor that won’t spin out when torque is applied. If you want repeatable assembly, fast installs, and a professional finish, our tee nuts do the hard work behind the scenes so your project looks and performs its best.

What Are Tee Nuts?

Our tee nuts, often called T-nuts, seat into a pre-drilled hole from the back of the panel and lock in place as the prongs press into the base material. Once set, they create a durable internal thread that accepts standard machine screws and bolts for furniture, fixtures, speakers, jigs, and anywhere you need a hidden, serviceable attachment. Because the head sits flush against the panel, you get a smooth face on the show side and a reliable clamp on the working side. 

Our range covers common imperial and metric thread sizes, with body designs that align to standard drill diameters for quick prep and predictable seating. Choose pronged or flanged styles based on your base material and the surface hardness you’re working with. The low-profile head keeps the front face clean when you need a flush mount, while the wide underside spreads load to protect the panel.

If your application calls for higher clamp loads or a slimmer profile elsewhere in the build, consider pairing your project with our Heavy Hex Nut for added wrenching surface, our Hex Jam Nut for jam-locking and low-clearance spots, or our Square Nut Thin when a compact, flat-sided nut helps prevent rotation in a channel or fixture.

BN 226 Tee Nuts

BN 226 tee nuts are designed to install into pre-drilled holes in wood or composite sheets and lock in place as the prongs or flange embed into the material. The result is a stable, spin-resistant anchor that delivers consistent thread engagement and simplifies repeat assembly and disassembly. Our BN 226 option is a shop favorite for cabinetry, furniture frames, test rigs, and fixtures because it combines fast seating with dependable pull-out resistance.

Materials and Finishes

We stock our tee nuts in corrosion-resistant zinc-plated steel for everyday shop and production use, along with stainless options for humid, marine, or high-cleanliness environments. Each finish is selected to balance durability, appearance, and cost so you can match the hardware to your conditions without compromising performance. Threads are precision-formed for smooth engagement and reduced galling during high-cycle use.

Installation Tips

Drill to the recommended diameter, insert the tee nut from the back side, and draw it tight with the mating bolt to seat the prongs cleanly. For harder species or laminated panels, a brief press fit before tightening helps the teeth bite evenly. Once set, our tee nuts resist spin-out and stay put under vibration, making them ideal for projects that move, flex, or see frequent service.

FAQs

What is a tee nut used for?

A tee nut creates a durable, machine-threaded anchor inside wood, plywood, MDF, or composite panels so you can fasten from the front without exposing a nut on the finished face. Our tee nuts are common in furniture assembly, speaker cabinets, workholding jigs, retail fixtures, and any application that benefits from repeatable, serviceable fasteners instead of permanent screws.

Are tee nuts strong?

Yes. When correctly installed into the proper material and seated flush, our tee nuts deliver excellent pull-out resistance and stable torque transfer because the prongs or flange distribute load across the panel. Strength depends on factors like panel thickness, material density, and thread size, but for their weight and footprint, tee nuts offer a very reliable hold that stands up to vibration and regular maintenance.

What are tee nuts made of?

We produce our tee nuts in zinc-plated carbon steel for everyday durability and in stainless steel for added corrosion resistance in damp or demanding environments. Both options feature accurately formed threads for smooth assembly, consistent clamp force, and long service life.
