Tee-Nut 1/4"-20 Steel Zinc 100 Pack

These tee nuts are designed to create strong threaded inserts in soft wood and similar materials. The three-prong base grips the surrounding material to resist pull-out and rotation during assembly. A pack of 100 pieces supports repetitive fastening tasks in workshop or production environments. Zinc-plated steel provides basic corrosion resistance for indoor use.

Furniture builders and woodworkers needing blind

Users who require a flush nut profile for bolt-on joinery in wood will find this design suitable. The pronged base installs from the opposite side of the bolt head, leaving a clean surface. Builders working with metal, plastic, or dense hardwoods should consider alternative fastener types. Applications demanding stainless steel or metric threads are not addressed by this item.

Thread size 1/4"-20 and three-prong configuration

The unified coarse thread pitch matches standard 1/4"-20 bolts and machine screws for compatible hardware pairing. Three prongs distribute holding force across the workpiece to reduce splitting in soft wood. Verify that the material thickness and density suit prong penetration before committing to the installation. No other thread sizes or prong counts are included in this pack.

Questions about this item

How do I install the 3-prong T-nut so the prongs grip the wood without splitting it?

Drill a clearance hole matching the barrel diameter, insert the T-nut with the flange flat against the surface, then tap it in with a hammer until all three prongs seat fully; the step most people miss is pre-drilling the hole instead of forcing the nut, which cracks the wood and leaves the prongs loose.

Will the zinc-plated steel nuts need any maintenance or replacement once installed in a project?

The zinc plating resists surface corrosion in dry indoor use; if the assembly is exposed to moisture or outdoor conditions, the coating can wear through over time and the steel may rust, so plan to replace the nuts if you see white or red oxidation on the flange or threads.

What is the first limit I will hit if I keep tightening a 1/4"-20 bolt into these nuts under sustained load?

The 1/4"-20 thread will strip in the nut or the bolt will yield before the steel barrel deforms, so the practical limit is the thread engagement strength of the coarse 20-pitch thread rather than the nut body itself.
