What the product is

This pack contains one hundred 3-prong T-nuts made of zinc-plated steel with a #10-24 thread. They are designed to be driven into soft wood so that a matching screw or bolt has a strong metal thread to engage.

Who this suits and who it does not

The nuts suit woodworkers and DIYers who need reliable threaded inserts for furniture, jigs or fixtures built from soft timber. They are not for anyone needing metric threads, stainless steel, or a smaller quantity than one hundred pieces.

What to check before ordering

Confirm that your project uses #10-24 machine screws or bolts and that the material you are fastening into is soft enough to accept the three prongs without splitting. Also verify that a pack of one hundred matches the scale of the job you are planning.

Questions about this item

What size drill bit and wood thickness do I need so the #10-24 thread and three prongs seat properly?

Drill a clearance hole for the #10-24 barrel and press the three-prong base into soft wood at least as thick as the barrel length; the prongs grip the fibres and prevent the nut from spinning when the bolt is tightened.

Will these zinc-plated steel T-nuts hold in reclaimed pine that already has #8 wood screws installed?

Yes — the #10-24 machine-thread accepts a matching bolt, while the three prongs bite into the surrounding pine independently of any existing #8 screws, giving a fresh load path in the same board.

After driving the bolt home, how can I confirm each of the 100 nuts is locked and not spinning?

Torque the bolt to the spec for #10-24 fasteners; if the nut does not rotate in the wood and the joint draws tight without the nut backing out, the three prongs have seated correctly.
