I tried to use Elmer Glue but it didn't work since the soft release would become loose.
Then I used blue Locktite but it didn't keep the soft release safe for long either. But I'm stubborn since I thought there's no way blue locktite should fail that soon, so I cleaned the thread and applied blue locktite again, and 6 months later the soft release is still sitting tightly so I guess it works this time.
