Can anyone identify this Unistrut support part?
I'm hoping to duplicate the unistrut system in the picture.
I'm trying to purchase both the square washer with the attached nut and the threaded bolt.
Sometimes its called a Saddle Washer, but I have checked multiple sources and cannot find one with a integrated nut.
I also can't find the bolt.Thank you in Advance
The threaraised floor.PNGded bolt appears to be 3/4".
 
Its just a stainless whatever length stud with a inch of thread...
Should be able to order something close to that from a nut&bolt supplier.
Kinda just looks like a 9/16" nut to me. The lack of all thread is just for strength... You still could make 'em.
 
It's threaded rod with washers and nuts. The square nut is available from Caddy (Erico)
 
Looks like four pieces to me...

1) Strut nut behind
2) Square washer in front
3) Threaded rod through the washer and into the strut nut
4) nut in front of washer

Plus the other nuts and washers to fasten the hanging strut
 
I agree square washer. A saddle washer goes over the edge of the strut. Two types of saddle washers which IMO are better for the application than a square washer.IMG_20240328_131420713~2.jpg
 
There might be a spacer tube thats placed over a threaded rod or bolt to get a consistent height.

Could be a contractor has NPT die heads and round stock to make his own hangers and such instead of carrying all thread. I think it used to be common in large manufacturing plants.
