Hello, I have had these for a while, and am unable to find any info. These were headed for the scrap bin at work, so I rescued them. The bolt size is 5/8". Standoff?  For glass? Thanks, Lou

What line of work is the company you're at  Lou? How many did you get?

Hello, Papadan. Thanks for the reply. I work as a trim carpenter, mostly commercial buildings, classrooms, offices, etc. I am not sure how many that I have, I dug this one out for the photo.Thanks, Lou

Maybe they are used upside down from the picture.
Some kind of hanger.

Hello, leg17. I am still looking, I will use your idea in my search!!!!

Stainless - I have to wonder if they're boat hardware.  You might look on some of the boat supply websites.

Hello, Bill. I will try that, we have a lot of hardware attached to the exteriors of the buildings. Thanks, Lou

Sometimes stainless is used in corrosive environments. 

Hello, Guys. I sent a picture off to my son, and I think he has it, It is a spider fitting for a cable net glass wall system. Here is the link  (http://www.spiderfittings.org/spider-fitting). Thanks for all the input, Lou

Or outside in the weather. If you work on new commercial buildings, they could be some kind of sign or awning mounting brackets. I'm thinking about how I could use them for a project.
