I am glad you identified and are on the road to repairing that bar. I would like to offer a worst case fix for stripped out dogging sockets. Obviously this is not really cost efficient unless your drive becomes a signifcant factor or the client insists on an immediate solution. This fix will probably out last the rest of the exit bar.
Strip down the exit bar and remove the dogging part. By sight, determine what size bolt is less than the cross section of the dogging socket. I usually get the client's allen key also as a reference. Drill the hole wider and deeper for the correct thread tap. Tap threads to the bolt size. (Kawneer is 1/4-20) Now coat the hole with JB Weld and screw in tightly the exact length allen set screw. Reassemble everything and collect your money.
The allen screw will not wear out like the original mild steel one does. The client may have to occasionlly grind down 1/4" from the tip of the allen key to get fresh corners which will make it work better on all of the bars.
Nothing is foolproof to a talented fool. Wisdom is not just in determining how to do something, but also includes determining whether it should be done at all.
