Oak is a heavy wood with high wear resistance. Its surface is rougher than birch and maple.

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

Steel inserts have high strength for durability.

Ridges on the barrel of these inserts make them less likely to split hardwood than inserts with prongs. They're often used in wood that has been cut across the growth rings.

Steel inserts have high strength for durability.

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

With only three prongs—fewer than our standard tee nut inserts—these inserts are less likely to split hardwood. They’re made of 18-8 stainless steel, so they stand up to mild chemicals and water better than steel inserts.
