Helicoil5521-7 7/16-14 Inch Coarse Thread Repair Kit

Q: Can it be used for a knuckle hole (bolt 7/16-1.50) to attach a caliper on the car? I stripped the hole.

Maybe... You should consider carefully what is at risk. If you choose to use the Helicoil, make sure sure you have enough thread engagement - use two if necessary an make sure you use locktite when installing them - clean the excess locktite out before intalling your bolt (so you can get it out again :) )

Q: Will this work on plastic with metal threads?

As long as your tapping into metal and not plastic.

Q: what is the size of the tap?

Sorry but the tap I got in the kit does not say what size it is. It just says "Heli-coil", "7/16-14 STI NF", "819-7", USE DRILL 29/64", "MADE IN CHINA". I don't know if it is a standard size or especially made for Helicoil inserts. Ken
