2001 leaf spring center pin question

One of my center pins got stripped out during AAL install. Was wondering if anyone knew the diameter of the head that fits into the hole in the axle. Can't find the exact pin locally so I have replacement on order but need to have something for the time being.

 

^I just used a hex head 14mm bolt... I don't know the size of the head though...

 

The round "dowel" piece that centers the leaf pack onto the mounting perch of the axle is 10mm.

 

Thanks...but... the bolt is 10mm or the end that goes into the axle perch is 10mm.....Guess I should have asked what the diameter of the hole on the axle is. Don't wanna get one that won't fit in the hole...I already have to deal with that enough...lolol

 

Oh wait...so the bolt is 14 and the head is 10???

 

In the pic below the short ones are OEM and the long ones are replacements that get cut to length.
The "head" is 14mm and the shank is 10mm. Many folks, for years and years just us a 3/8" socket head cap screw. The cap screw (Allen Head) is functionally identical in all respects.

 

Right...duh, of course the head wouldn't be smaller than the shank. Thanks for the help

 

3/8 bolt size with a 9/16 head is what is most used.
