That is a spring shackle for a old car or truck back then you greased them. They were replaced by rubber mounted spring shackles.

 Don't know.  its not like any spring shackle I've seen. If you put grease in the end it would grease the threads but not the leafs. I'm guessing automotive but not convinced on automotive what.

Go to a search engine and type in Dodge spring shakles 1940s and you will see several pictures of them. I was in the auto wrecking trade for over 35 years and removed and replaced many of them.

That is  a shakle,not a u-bolt. One side goes in the bracket on the frame and the other in eye hole of the spring. Several different car makers used this system. Not the best setup.

Shackle on top, u-bolt on rear driveshaft. See the beautiful old Buick below:





I hope this helps to clear up the difference.

It has something to do with keeping the whole thing tight. One side of the car had right handed thread on both upper and lower while the other had left and right.

Never seen an open ended version in the UK - they are usually found with a plate either side of the spring and hanger....



as per this repair kit for a 4x4, and this from the same web page...
