thread size

[91gpse]

I need to retap a water temp sensor on a buddy of mines 3.1 mpfi then put my old one in it. I need to know the thread size so I can retap it (the numbnut cross threaded his in).

take the sensor to the hardware store and find a nut that fits, that's your thread size.

tried that.... noone has one that fits... its a metric fine thread

Take it to where you are buying the tap then find the die that fits it.

from the look of it im going to have to go to an actual tool and die shop...

I work at hardware part time, we have all sorts of metric fine threaded nuts/bolts (fine and extra fine).
We have the fine taps too. Is there a Do It Best around you?

[91gpse]

dont think there are any in michigan...

[TheOtherNick]

Measure the hole with a caliper.

[danielle15]

Well it was worth a shot.
Any Ace Hardware's?
Fastenal? (If you have one close to you, you'd be sol till Monday morning)

I'd say check Lowe's or Menards or the like, but I'm not sure that they'd have metric fine thread.

everywhere ive been says they dont have taps big enough for how big the sensor is.

[91gpse]

i was asking anyone if they knew so that i could order one online..... or if i have to from the dealer...

[TheOtherNick]

dealers not going to have a tap. Take the sensor to a machine shop and they will tell you the thread if you dont have a caliper or mic.

i have a caliper but its not gonna tell me the actual thread size... its a 16mm but whats the thread itself though?
