Barry,
Here's the data for the 12 OEM bolts I can find (there's 4 more someplace).
.4370
.4370
.4365
.4375
.4360
.4385
.4390
.4380
.4370

Avg = 0.4374
4 Aircraft spruce 7/16s
.4350
.4355
.4355
.4360
Avg = .4355
The OEMs appear to come from two different manufacturers from the head
markings with one manufacturer being consistently larger in diameter than the
other.
The difference, on average, between OEM and Aircraft Spruce ANs in 0.0019
inches (0.44%) larger for the OEMs. The max difference is 0.004 (0.4390 vs
0.4350 (0.9%)) inches larger for the OEMs and the min difference is 0.000
for the OEMs (0.4360 vs 0.4360 (0.0%)).
This data is consistent with your measurements. The OEMs are always
slightly larger than the ANs.
You can have 4 bolts measuring 0.4380 (using Mitutoya calipers) or
greater. Send me your address and I'll mail them out.
Have fun today,

I'm hoping to find at least 4 original bolts for the half shaft flange
connections.
A PO has lost 4 of mine.
Perhaps someone has a few used ones left after replacing the complete set
with new ones?
The originals were 7/16 x 20 x 1-1/4. The shank (unthreaded) portion
measures 0.4385" dia
The new ones I bought from Aircraft Spruce are fine except the shank is
only
0.436" dia
Because these act as drive pins, I'd really like to use originals if I can
find four of them.
Thanks
Barry
