1/4" T-Nut, also called a 1/4"-20 tee nut, four-prong T-nut, or threaded insert nut for wood, is designed to create a strong internal thread in wood, plywood, particle board, loudspeaker boards, furniture panels, and climbing wall panels. It provides a flush, durable, and reusable fastening point for bolts, screws, climbing holds, furniture parts, and woodworking assemblies.
KYA Fasteners supplies 1/4"-20 zinc plated T-nuts made from carbon steel with four strong prongs and deep internal threads. The zinc-plated surface helps improve moisture, oxidation, and corrosion resistance, while the four-prong design helps the nut bite into wood and prevent rotation during tightening.
1/4"-20 thread: Standard coarse thread size for woodworking, furniture, climbing wall holds, speaker boards, and general fastening.
Four-prong design: Four sharp prongs bite into wood, plywood, particle board, and soft panels to resist turning.
Zinc-coated carbon steel: Provides strength, hardness, and better resistance to moisture, oxidation, and corrosion than untreated steel.
Flush installation: Creates a clean threaded insert on the back side of wood panels without visible hardware on the front side.
Reusable threaded fastening: Allows bolts to be removed and reinstalled for furniture parts, climbing holds, fixtures, and removable assemblies.
Bulk supply support: Suitable for hardware distributors, furniture factories, climbing wall suppliers, woodworking shops, and OEM packaging projects.

1/4"-20 T-nuts are used wherever a strong internal thread is needed in wood or board materials. They are especially useful when the front side needs to stay clean, the connection needs to be removable, or the fastener must resist rotation during repeated bolt tightening.
Rock climbing wall holds and climbing wall panels
Wooden furniture, chairs, tables, cabinets, and shelving units
Plywood, particle board, MDF, and soft wood projects
Loudspeaker boards, speaker cabinets, and audio equipment panels
Woodworking jigs, fixtures, removable panels, and DIY assemblies
Hardware kits, repair projects, and OEM furniture fastening systems
A T-nut is installed from the back side of a wood panel. After a pilot hole is drilled, the barrel of the T-nut is inserted into the hole and the flange is pressed or tapped until the prongs embed into the wood. The prongs help prevent the nut from rotating, while the internal 1/4"-20 thread receives a matching bolt from the front side.
| Step | Installation Guidance |
|---|---|
| 1. Confirm Bolt Size | Use a matching 1/4"-20 bolt or screw to fit the internal thread. |
| 2. Drill Pilot Hole | Drill the hole according to the barrel diameter and panel thickness. Avoid oversizing the hole. |
| 3. Insert from Back Side | Place the T-nut barrel into the hole from the back of the wood panel. |
| 4. Seat the Prongs | Press or tap the flange until the four prongs fully bite into the wood surface. |
| 5. Tighten the Bolt | Insert the bolt from the front side and tighten carefully to create a strong, reusable threaded connection. |
| Selection Factor | What to Check |
|---|---|
| Thread Size | Confirm 1/4"-20 thread and match it with the bolt, screw, or climbing hold hardware. |
| Base Material | Check whether the material is plywood, soft wood, particle board, MDF, furniture board, or speaker board. |
| Panel Thickness | Select the correct barrel length and flange size according to board thickness and load requirement. |
| Prong Design | Four-prong T-nuts are recommended when stronger anti-rotation grip is required in wood panels. |
| Surface Treatment | Zinc-plated carbon steel is suitable for many indoor and general woodworking projects. For severe outdoor or high-corrosion environments, confirm coating requirements before ordering. |
| Packaging Requirement | Confirm bulk quantity, bag packing, carton packing, private label, barcode label, and export packaging requirements. |

1/4"-20 T-nuts are used to create strong internal threads in wood, plywood, particle board, furniture panels, speaker boards, and climbing wall panels. They are commonly used for rock climbing wall holds, furniture assembly, cabinets, fixtures, and woodworking projects.
KYA 1/4" T-nuts are made from zinc-coated carbon steel. This material provides good strength, hardness, and better corrosion resistance than untreated steel.
The thread size is 1/4"-20. Buyers should use matching 1/4"-20 bolts or screws to ensure correct fit and fastening performance.
A four-prong T-nut provides better grip in wood and helps prevent the nut from turning when the bolt is tightened. This is useful for climbing wall holds, furniture panels, and reusable wood connections.
Zinc-plated T-nuts provide moisture and corrosion resistance for general use. For long-term outdoor exposure, wet environments, coastal areas, or critical applications, confirm whether stronger coating or stainless steel is required.
Drill a correctly sized pilot hole, insert the T-nut from the back side of the wood panel, and press or tap the flange until the four prongs are fully seated. Then install a matching 1/4"-20 bolt from the front side.
Yes. 1/4"-20 T-nuts are commonly used for rock climbing wall holds and plywood climbing panels. For safety-critical climbing wall projects, confirm bolt size, panel thickness, load requirements, and installation standards before use.
Yes. KYA can support bulk packing, retail packaging, private label, barcode labels, carton marks, and export packaging for T-nuts and other fastening products.
