WHAT BOLT SIZE IS ON A GRIFF ARB DROP LINK. ??

[SteveSPG]

AS TITLE, NEED TO ORDER SOME ROSE JOINTS AND NEED THE BOLT SIZE.

[Barreti]

I've got my old Steve Heath drop links on the bench.
How do you want me to measure the bolt

[SteveSPG]

Ideally the width of the shank which I guess is imperial. Plus bolt length

My sh ones rattle. Just going to order new parts from McGill to replace

Drop link and vernier in hand.

Nuts 17mm
Top and bottom bolts are the same

Bolt - not Rose joint - the one which joins the drop link to the ARB/wishbone

Looking at the measurements I've got coming up its an imperial bolt but I'll give you both sizes
Shank plus thread = 1.75" 44.6mm
Shank taper in to the thread.
Shank to taper 0.55" / 14mm
Taper 3mm
Shank diameter 9.84mm / 0.38"

Thread length 1.07" / 27.34mm
Thread diameter 0.386" / 9.81mm

Shank plus thread length 1.76" / 44.7mm

Entire bolt length 2.0" / 51.7mm

Is that what you wanted or was it the rose joint thread?


Rose Joint thread
Diameter 0.375"
Thread length 0.86"

I'd say both rose joint and bolt are imperial. They are certainly the same thread because both screw nicely into the ali body.

I don't have a TPI gauge - god knows why not!
