Graph Tech confirmed they've changed the molds a couple of times. It was originally 5.14mm. It switched to 5.2mm temporarily. They have since moved it up to 5.33mm. Yet, at the time I'm writing this, all of their packaging still says 5.14mm and their website still lists both 5.2mm and 5.33mm, depending where you look. So, when purchasing their traditional bridge pins, they can actually measure anywhere from 5.14mm up to 5.33mm at the top of the neck (+-0.03mm tolerance). Eventually, when all the older ones are all sold off (from all levels of distribution), they will all be 5.33mm (even though it says 5.14mm on the packaging). Hopefully by then they also change the packaging to match the new specs.
