do you tightern the allen and then put a socket on the nut and give it another 1/8 turn or so?

I had that issue as well....untill I got them dialed in....tighten the allen lock down THEN I get the allen key and box wrench lined up one on top of ech other and give (BOTH at the same time) another 1/8th turn or so...they will "squeek"....haven't had an issue since.

I have a set of ratchets and sockets that do - for use on long studs primarily. MAC makes them and I bet so do others.

No thread locker, its really quite simple. You are simply not listening. Set needed lash with the 5/8ths poly then simply run the set screw in till it stops. Now go another eighth to a quarter turn with the polylock AND setscrew together. Never come loose again.

youre running a solid roller, therefore you are running a specific lash value.... recheck your lash after locking the allen screw and giving the poly another "crank till it squeaks".... I found that I needed to set my lash bout 3-5 thou loose, then give the poly that extra crank to lock it. recheck lash to make sure its in spec after "final lockdown" just my $.02
