slide bearing assembly
we have an old detail showing a furon flourogold slide bearing assembly supporting a steel wide flange on a seated connection.  the detail does not depict a bolt through the seat and wide flange.
i have to imagine that a bolt would be required here, connecting the wf to the seat, but how would that work without seizing up the assembly? i seem to remember that bolts are not allowed to be finger tightened per aisc, but would standard bolts in a long slotted hole work here?
thanks for your help.
you may or may not need a bolt depending on whether your beam is restrained by other elements or not.  in my experience i have seen the use of slotted holes with a bolt for this type of application a number of times.
i like your idea of using machine bolts instead of a325.  with the a325 bolts some one might torque them down, thinking they need to be that way.

thanks for the quick reply. sorry for the miscommunication but my intent was to differentiate between an a325 bearing bolt and a a325 slip critical bolt.  im not sure i would use a machine bolt.
i would recommend using a seat plate with teflon pad (no bolts) at the base in conjuction with a web angle connection with long horizontal slots and hand tightened bolts with marred threats to guide the beam and prevent it from falling off the seat.   
you can get guided bearings with lugs on the side of the upper plate to prevent lateral movement.  if uplift resistance is required, those are available as well.  all without any bolting.
