What's very disturbing is the type of failure. The stem was in the Honeymooner's D$#K position (i.e. +45 degrees) nice and tightly screwed in. It failed by dropping to the Retiree's position (i.e. -45 degrees) and is STILL tightly screwed in! Go figure how that happened.
I haven't torqued the stem in 1 month and its been solid till now.
