    Tapping Threaded Inserts for Soft Metal

    Image of Product. Bottom orientation. Threaded Inserts. Tapping Threaded Inserts for Soft Metal.
    No need to tap the hole, these inserts cut their own threads into soft metal, such as aluminum. The teeth dig into the material to keep them secure when installing and removing screws. To install inserts with a wrench, thread an insert and two hex nuts onto a bolt. Then, grip and turn the top nut to drive into a drilled hole. If you need to add a lot of threaded connections quickly, use an installation tool with a ratchet wrench or drill press. These inserts are comparable to Tap-Lok inserts.
    Thin Wall—Use these inserts near the edge of workpieces or wherever you only have space for a small hole. They're also lighter than thick-wall inserts for applications with strict weight limitations.
    Standard Wall—Stronger than thin-wall inserts, these are your go-to choice for threading most holes and replacing drilled out threads.
    Zinc-Plated Steel—A step up from plain steel, the plating withstands occasional exposure to moisture.

These inserts cut their own threads and lock into material, so they won’t budge when you install or remove a screw. To install inserts with a wrench, thread an insert and two hex nuts onto a bolt. Then, grip and turn the top nut to drive into a drilled hole. If you need to add a lot of threaded connections quickly, use an installation tool (not included) with a ratchet wrench or drill press.
