I don’t have a clue what it means, but it was stamped on one of the bolts holding together a bridge over the Big Darby creek in Prairie Oaks Metro Park.
Yup. No real tie to this post other than the use of the phrase in response to a challenging question 🙂

Bolt heads typically carry marks to signify their strength and type. Although you wouldn’t think about it, the Civi’s do designs to take into consideration the strength of each fastener. Think about it – it’s a war between the holes you have to poke into the metal and the strength of the fastener. A simple link: http://www.unified-eng.com/scitech/bolt/boltmarks.html. Otherwise, there is an ASTM standard for bolt head markings. In a few thousand years, they will dig up this bolt and have the same question that you posted.
Isn’t Galt a character from Atlas Shrugged?
