Hi guys. I need to know the thred size of a glow plug so I can buy a tap and die. Thank's Jack.

Jack,

glow plugs have 1/4-32 threads . Can be a bit hard to find.

Ken

Ken thank you very much. Jack

try mcmaster carr www.mcmaster.com, or microfasteners for this tap

I tried the Mcmaster link with no luck. I think Harry Higley sells the tap and die,


Jimmy

If you remove the "." at the end of the link it will work.

FYI

I must ask. Why do you need the die if you are going to tap the hole?

Ed S

No he doen't want the die. When he gets the PRICE of the tap it will KILL him.


.............................. "buy a tap and die" get it ?

Then they can play TAPS for him . In that case it's DIE and TAPS !

All this wierd humour.

It just Taps me right out!

Ed S

Hey! I thought it was funny.

It's good to have a die to correct poor threads on the glowplugs before you screw 'em into your engines. Most stripped glow plug holes are caused by poor threads on the glow plug.
