Thread Pitch (tow hook)

[jdlynch99]

Any one know what the thread pitch is for the tow hook, thinking about making some custom stuff for mine.

I could figure it out but I'd thought if someone already had the info it would save me the hassle.

Thanks

I make it a round-shouldered variant of metric "Acme" thread - M16x4.

N.B. The thread diameter actually measures just over 15.5mm. I suspect it is slightly reduced from the standard 16mm (and rounded) to make it easier to hand thread-in and remove. That argues that it may be difficult to solidly tighten, though a full profile M16x4 might do a little better.

Thanks, now I gotta see if I have the right gears for my Smithy to cut it.

Have to wait til I get home tonight.
