    Screw-to-Expand Press-In Threaded Inserts For Through Holes in Plastic

    Image of Product. Bottom orientation. Threaded Inserts. Screw-to-Expand Press-In Threaded Inserts For Through Holes in Plastic.
    Press these inserts into a through hole from the underside of your material, and the flange keeps them from going too far. Then, thread in a screw to expand the insert, driving the sharp diamond knurls into the plastic. Install using an arbor press or similar pressure tool. Installed length includes the flange.
    Brass—Conductive and nonmagnetic, these inserts are useful for electrical applications. They resist moisture but aren't as strong as steel inserts.
    18-8 Stainless Steel—The choice for wet and outdoor environments, these inserts resist rust and mild chemicals. Since they’re lead-free, they can be safely recycled.
