Quick question on Magnum center cap retainer bolts

[moparedtn]

Fred has a set of repro Magnum 500's (15" chrome, not the "trim ring" factory originals).
Does anyone know offhand what size the little center cap retainer bolts/screws are inside?
Going to the tire joint tomorrow and want to bring a socket with me.
Thanks!

thread pitch is 1/4-20
head size can be either 7/16" or 5/16"

A nutdriver works well on those.

But not 3/8"?

No, they should be a reduced head size.

Blue thread locker never hurts

No, they should be a reduced head size.

I don't even know what that means.


Ok, so the standard hex head size for 1/4" is 7/16" apparently, so I'll figure to bring that along
with the immediate adjacent sizes on either side?

Both bolts are 5/16"x18, but the heads are a different size. Left is 7/16" and right is 1/2".

5/16, 3/8, 7/16, 1/2. A little extra weight in your pocket, but saves you a trip.

Can't go wrong with the whole socket set! Lol


Can a guy get a straight answer around here?

I have one cap that I guess the PO lost the 5/16” head bolts. A pair of 3/8” head bolts fit fine inside the retainer.

Just ckd, The ones in mine are 5/16" hex washer head type screw

This is gonna wind up being the "correct answer" methinks.
