Going to be installing a 5/16" Helicoil shortly. A couple of questions. The directions say to install the Helicoil so top is 1/4 of a turn below the top. The hole is about 3/4" deep and the Helicoil is about 1/2" long.
Here is the question:
Do I tap the hole all the way to the bottom and then just screw the Helicoil so its 1/4 turn below the top? Or tap the hole only deep enough so the Helicoil will bottom out at the end of the threading when the top is 1/4" turn from the top?
