Hydraulic slide out Question

[Kellerdj]

First time with the Hydraulic slide out and was wondering if there is supposed to be a gap between the nuts and the plate for the slide bar see picture. As both slides are spaced exactly the same and surprised it would be done on purpose as the threaded part has to go through the bracket before the nuts make contact to pull in or out the slide. If it is supposed to be tight I would assume just tighten single nut and is there any torque requirements?

Thanks
