Actually on reflection, I could be mistaken. They might be 5/16 course thread, in which case they will go only about 22 LBFT, but again, this isn't rocket science and it's not hard to figure out. If my delivery upsets you so, please pretend I sent along some baby powder and a pacifier. The information I am giving you is correct for each size fastener, yet, you choose to be a pansy and be sarcastic about my delivery instead of a simple "thank you". Nobody gets paid to help people out around here. It's taken me and others decades of experience to know this stuff. We're sharing it for free. You might think about that.
