Could be, misguided that is. I have seen comments where the "unmarked" bolts are simply rejects from lots of higher grades that didn't meet specs. If so, then they could be anything. Dunno if this is so or not. One would think that if it is, they would have to grind off the markings on the cap to make them unmarked, unless they put those markings on after they make and test the bolts. Or maybe they make the bolt stock first, test it before completing the bolt making process. and just make the stock that doesn't meet specs into unmarked bolts. Not the common hardware-store-grade ones. Not every bolt is tested, as the test itself destroys the bolt. The same logic that applies to fuses is used here, they're never tested, rather a select amount from each lot are. If a lot does not meet specs, it's usually recycled. During the manufacture of common bolts, the markings are stamped in when the heads are formed. It's based on knowing the type of steel that is being used - and there are hundreds of types - and the heat-treating process that will be followed. This must be done before treatment while the steel is still (relatively) soft.
Who the hell let all the morning people run things?
