Large threads cut into softwood such as particleboard for a strong hold.

Made from brass, these inserts are nonmagnetic, mildly corrosion resistant, and electrically conductive.

These 18-8 stainless steel inserts have excellent resistance to chemicals and may be mildly magnetic.

These 18-8 stainless steel tee nut inserts have better corrosion resistance than zinc-plated steel tee nut inserts.

Fewer prongs than other tee nut inserts reduce the risk of splitting hardwood—these inserts have three short prongs.

Six prongs around the barrel of these inserts provide a strong hold and prevent them from loosening and twisting.

Use where vibration is a concern—these tee nut inserts have distorted threads that lock screws in place.

A closed end seals out elements and protects the threads on these inserts from debris.

Knurls hold these inserts in hardwoods such as oak, maple, and walnut to prevent twisting.
