The guage "threaded body" is equivalent to 3/4 inch. So if you were to drill a hole you would need a 3/4 inch drill bit.
No, I don't think so, I believe the hole on your grill is a smaller diameter. The "Nexgrill" guage is made to screw in a 1/2 inch "npt" hole or sit outside of a rather large hole or similar size hole. if you use it, it may not work as you may expect.
The guage is measuring "ambient" air (temperature) surrounding it. No "temp guage" should read "0" when you get it.
Max temp is 500 degrees
It can be left attached on the outside of the smoker. If left inside the smoker, it will still read temperature but the face will be covered in smoke...
The guage come with a washer and a nut.

This is a general temperature gauge that will fit most units.
