Antique and Poster Style Bed Bolt

Kennedy had the best price by far, and shipped very quickly, but the bolts are not exactly as advertised. They are 5 3/8" long, not 6". The nuts are oversized and threaded off-center. I went to the local hardware store to get replacement nuts and found the bolts are not 16tpi and not metric. They are 3/8's by 14tpi and no stock nuts will fit. I will make do with the bolts and grind down the nuts to fit my project.
