Steel Tee Nut Inserts for Wood
These inserts have four prongs on the flange to resist twisting in hardwood and softwood. Hammer them into a drilled hole to install. Installed length includes the flange.
Unfinished steel inserts are best for dry environments, since moisture will cause them to rust. They are ready for painting.
Zinc-plated steel inserts are mildly corrosion resistant in wet environments.
Black-oxide steel inserts have a dark surface color and are mildly corrosion resistant in dry environments.

Mil. Spec. Rivet-Mount Nuts
Create threads in hard-to-work areas—where you can’t reach the back of a workpiece, or material is too thin to be tapped. For a strong grip, these nuts have distorted threads that increase friction with bolts. Because they mount with two rivets, they won’t spin when you’re tightening screws. However, these nuts do move inside their retainers, which lets you install bolts at a slight angle; use them to align with off-center parts. All meet military guidelines for dimensions and material.
Cadmium-plated nuts resist corrosion in industrial and saltwater environments, although will lose their corrosion resistance over 450° F. The cadmium plating also adds lubricity, making these nuts easy to install.
A286 stainless steel nuts are corrosion resistant. Silver-plated stainless steel nuts withstand temperatures up to 800° F. The silver plating also adds lubricity and prevents seizing caused by friction between nuts and bolts.
Lubricated nuts thread onto bolts smoothly.
