Stainless Steel T-Nuts
What are stainless steel T-nuts? Stainless steel T-nuts are pronged, flanged nuts that press into wood or composite to create a strong internal thread for receiving bolts from the other side. Made from stainless, they resist rust in damp and outdoor wood where a plated T-nut would corrode and stain the material.
How T-nuts create a reusable thread in wood
A T-nut is driven into a drilled hole so its prongs bite the wood and its flange seats flush, leaving a durable machine thread on the back side. That lets you bolt and unbolt parts repeatedly without stripping the wood, which is why T-nuts are common in furniture, jigs, climbing walls, and knock-down assemblies. Stainless keeps the insert and the surrounding wood free of rust staining outdoors.
Why choose stainless steel T-nuts
- Reusable thread: bolt and unbolt without wearing out the wood.
- Strong hold: prongs grip the wood and resist spinning.
- Corrosion resistance: no rust staining in damp or outdoor wood.
- Clean back side: flange seats flush against the surface.
Common applications for stainless T-nuts
- Furniture and cabinetry with removable bolts
- Jigs, fixtures, and knock-down assemblies
- Climbing walls and equipment
- Outdoor and damp wood installations (use 316)
Stainless Steel T-Nuts FAQ
How do I install a T-nut?
Drill a hole for the barrel, then press or tap the T-nut in from the back so the prongs bite and the flange seats flush. The thread is then ready for a bolt from the front.
Will a T-nut pull out under load?
Properly seated prongs resist pull-out for most uses. For heavy or repeated loads, choose a longer-barrel or screw-in insert and back it with adequate material thickness.
Why use stainless T-nuts in outdoor wood?
Stainless will not rust and stain the wood around the insert, which is a common problem with plated T-nuts in damp or exterior use.
