Tapping Inserts for Soft Metal
![](/prerenderstable/mvPRE/contents/gfx/imagecache/902/90240a003p1-b01-digitall@halfx_636849161626359197.png?ver=imagenotfound)
Also known as Tap-Lok inserts, these inserts cut their own threads in soft metals such as aluminum, so there’s no need to tap the hole. Install them into a drilled hole with an installation tool and a ratchet wrench. Installation tools can also be placed in the chuck on a drill press and turned by hand.
