So I have a size 10/24 helicoil but the tap they sold me (a 10/24) is too small

They did not have a 10/24 heliCoil kit

What Tap size do I need so that my Helicoil will screw down into it?

Thanks in advance
:cheers

Stunts, Helicoil taps are a larger dia. with the same pitch. They aren't actually a size that you can ask for. They are made specifically for helicoil inserts and not (as far as I know) used for any other purpose. The 10-24 should represent the bolt size that will fit into the inside the helicoil insert. The correct tap will come in the kit but most places sell the taps seperately also. Hope that helps!

10/24 Heli-Coil

The drill size for a 10-24 Heli-Coil is 13/64" (.2031") for Aluminum and #5 (.2055") for Steel It takes a special Heli-Coil tap (3CPB or 3CPA); A regular tap won't work; You need to get the Heli-Coil Kit (5401-3)!!! :thumbsup

you guys rock!! Unfortunately everywhere I have gone, has not had the 10/24 KIT.... every other KIT has been present but the 10/24. I can't go any bigger on my drill hole as it is for a wheel on my cobra.....

A regular Tap will not work in the correct size? because of fine vs. course thread?
:confused

If you can't find it local, I have ordered the kit on line and gotten it the next day. they have many warehouses and 24-48 hour delivery.

It may be the quickest way.:thumbsup

Good luck!
