DIY Guide to Installing Helicoil Thread
Also known as EZ coil, all are the same by the end of the day. However, you’ll install that into a chunk of stainless steel, so let’s get started;
Get an EZ coil kit, you’ll get all directions on the backside telling how to install a Helicoil. Then, you have a thread repair kit, take out all inserts. Get a tap, set tool, and Helicoil. There would be a piece of a bent coil on each side, this is the tool that sets it.
It has a little groove in the center of this tool which you can easily see. That little bent piece from the Helicoil goes on the bottom of the tool. You’re going to have to be about 3/8 of an inch deeper to repair thread to have the room to set coil in there because at the end, you’ll have to take a hammer and you have to bang the head to get rid of that piece
So, if it’s a spark plug or a bolt that has to go through, that Tang is going to prevent the bolt from going through. Now you have your punch and drill bit. Let me tell one more thing, on a ¼” -20 x 1.5D, now what does it mean? This means the length is 1.5; it’s one and half times the diameter of Helicoil. This should be 0.375 in length, and this is because the diameter is ¼ in. so 0.375 would be the length which is one and a half times the diameter.
Typically, they’re either one time the diameter, so ¼” long, one and half times the diameter which would be 0.375, or two times the diameter and typically longest you’ll ever get in a Helicoil. In that case, it would be half-inch long overall.
If you get helicoil and measure it, it’s goping to be smaller in length. Which they’re quoting as 1.5 times, which is 0.375 long is not for when it’s compressed, but when its installed
Step 1 – Get your pre-loaded punch, and punch a hole or starting point for drilling
Step 2 – Drill the hole
Step 3 – tap the hole
Step 4 – Install the Helicoil. Now, take the helicoil, put the tang over the tool, and start sctrewing it in. apply pressure as much as you can that it gets down about 2 turns from the top of the whole.
Step 5 – Once they’re in there, it’s hard to back it off. Take your hammer, and hit it.
Step 6 – It gets Broke off, now take your ¼” -20 hex cap screw and thread that in
The helicoil is installed finally!
