650 powder safty bar screw backing off

[problemchild]

Well here i am on another issue with my press. The screw behind the spring that keeps the powder bar from sticking is backing off and coming loose during reloading. It has done this twice now while loading. I put tape on it last night so it couldn't do it a third time. With the screw backing off the powder charges are all over the place from under min to over max. My powder alarm kept going off but you could not really tell a difference in a few grains by looking in the case. I grabbed one and measured it. Its was under, the next was over then under, then over.

What can I do to fix this? Should I put some of the thread anti-vibration lock on it?

you mean the blue plastic wing nut? if so that should the spring should jsut touch no more than that is is just a saftey thing and the spring should not be copressed at lease thats how i run it. look i the manual it will exsplan the set up.

also since the ?nut is stasmpled steel it maybe worn out if you have had presure on it call dillion and get a new one
