bolt manufacturer head marking

[mtull]

Does anyone know who the original manufacture was that produced bolts with head markings ELH (1st attached pic)?  I'm hoping a name will help with my search.  I shamelessly downloaded image from @Jay Bee post in the Parts Wanted section.   I'm trying to find two bolts for the wiper arm pivots (second pic).  I forget what the size is for the wiper pivots bolts are.  I've looked over the AMK site in the bulk section and found some that are close.  Aftermarket venders offer wiper pivot bolts but none I've seen have bolts like the second attached pic.

Thank you
M.

Thank you for posting.  When I first saw your post I embarrassingly chucked to myself as I recall seeing page 3.0-7 - 2 in my fastener guide book and assumed I must have missed the Fastener Manufacture's list.
I searched a bit thought the guide and it appears at first glance my older version (12) of the fastener guide doesn't have the aforementioned information.  Thanks again for posting, the information was helpful.

I frequently use the search feature of the forum and occasionally resurrect long dormant threads as well.  Although I wasn't actively searching for the information you provided it was still on my list of the things to learn about.  I appreciated your help.
Hopefully you'll have the time, energy and health to participate on the forum more often in the near future. Best of luck with your 1973 340 Barracuda, there great looking cars!
