Off hand I don't know, if I did I would have included it above. I wrote the above first thing this morning before coffee.

Awesome pics, Mike.
I have often thought "They cross-threaded the bolts" when reading about some members' difficulty installing these.
Remember, everyone........ If bolts are hard to tighten in the first one or two turns, STOP!
Realign and try again.
It is no coincidence that man's best friend cannot talk.

Nice Thread Mike! It is a good idea to use a lubricant as you did being that the bolt and housing are dissimilar metals and galling can occur. Anti-seize is a good option also.
Mine would get very slightly loose after a lot of use. I used blue(removable) Loctite and haven’t had to tighten them for years.

Re: FLEX 3401 Bail Handle Bolts - Installation and Tightening
Chances are those are either 6mm or 8mm low head socket cap screws. If it is a 6mm then the socket size is 5mm. If it is 8mm, then the socket size is 6mm. When trying to determine the proper tightening torque value, there is a big difference between dry torque and lubricated torque. The torque values listed in most manufacturer's charts are lubricated torque values. A light oil or Loctite 242 will provide the correct lube to achieve the proper values. 14.5 N-M for 6 mm and 35 N-M for 8 mm. Dry lubricated torque values are about 25% higher than lubed values.
