Outer Limits 4x4 Board

Basically as the title says. I need a 14 volt glow plug for a project and these seem to be the only ones i can find.

I need to know the size so i can try and find a thread tap to suit before i get too carried away.


Thanx guys, and ill reveal all once i get this project sorted out

M10 x 1.25

its a pretty uncommon thread from what i can gather, was trying to make up a compression tester for my 2H but the thread wasnt normal (measured em with a thread guage but cant remember what it was)

10x 1.25 mm

thanx, Now to find a tap.

Cheers

Its not that uncommon on most japanese cars/trucks. Finding a tap should be dead easy.

found a tap, got my glow plugs in the mail today, Then i wondered what size drill bit i need to use. I have never had to do a tap before .

Im guessing a 10mm, but im unsure.

Help please ?

Cheers

usually 9mm but this chart http://www.engineersedge.com/tap_drill_chart.htm says 8.8mm.......hmm dont even know if that size exists in drill bits

make sure u use the 8.8 drillbit otherwise the thread wonr be a tight fit it will slop around and wont seal properly..if your using glow plugs for sumthing i gather it might have compression so use the right drill and tap first time. cheers batcho

Thanks guys .

Have a virtual beer on me

An 11/32 drill bit will be much easier to find.
