I want to be able to adjust the black angle iron horizontally as i turn the bolt The nut is welded to the bracket...Is there another way to do this?
maybe with an addition of a shoulder bolt might work
Is this a constant/daily adjustment or is it a 1 time set up adjustment?
I am assuming the angle iron is welded to the tube in the background?
If it is a 1 time adjustment I would use a set screw with loc-tite on it to set it.
Multiple adjustments I would use something close to what you have using either a weld nut or a pem nut with a jam nut on the back to lock position. Also I would radius the end of the bolt to not mar the surface of what the bolt will be pushing against.
*Edit* You must have been editing your initial question while I responded.
A bigger idea of what you are trying to accomplish would help clear it up. The weight of the structure you are trying to move along with how far it has to move would be helpful. A bigger screen shot looking at it might help. Also what is this frame hinging on? You push with the bolt, where's the pivot point for it move around?
I would suggest buying a Heavy Duty Black Nut and machining a circle on one of the faces, then drill the matching hole in the angle, this assures a nice fit, plus the heavy duty nut doesn't distort as much during welding...
For welding nuts to the angle we use this.
I was mistaken. You want to know how you would guide the black angle iron as you adjust the bolt. Yes you can add a shoulder bolt to guid the angle if the not needing precise alignment.
ok, so with this I am able to adjust the angle forward but not backwards. Other words, i would not be able to pull the angle back....
is there something i can do so it will be able to the adjust angle back and fourth as I turn the bolt?
Make two holes across a bolt for two pins and add two washers to both sides of the web of your beam.
The second nut is for fixation.
make the holes through the threading?
this might work... Can I buy these bolts online?
I don`t know your (USA probably) market, sorry. Any workshop can do this. And even you can do this from standard bolt by a drill.

My first reaction was "why do they use Grade 8 bolts for leveling/adjusting?"
Anyway, if you have room in the angle (or use unequal leg angle) you could have a jack bolt as shown with a clamp bolt right next to it. These are very common for leveling and holding tooling down.
If you had enough room you could make it a lot more complicated by welding a stud to the 'moving' part and then have a captivated nut in a clevis on the angle part.
James, I took pictures of bolts from the internet to show how to do holes in threading. There is no need for Grade 8 for adjusting and there is no need for jack bolt
I was just responding to the original post. Russell's original post image shows a Grade 8 bolt (6 hash marks on a HHCS).
Seems to be that the spring pins would be a B**** to install....
Honestly, the first thing that I thought of was to use one of these:
Knurled Screw Jacks (Heavy) | Carr Lane
Or one of these:
Heavy-Duty Screw Jacks | Carr Lane
Threaded through your nut. You would need more room, and it would might be too costly/over engineered.....but the heavy duty ones have a built in locking nut and are designed to withstand a lot of pressure without moving.
