Just to be clear, it depends if you measure the coarse thread to the end of the threads or the bevel (.9 to 1.0).

I asked because the KB block has studs with about 1.75" on the coarse end. But the block has a counterbore about 0.25" and the studs have a small stand off on the end, so less than 1.75" is engaged in the block threads but much more than 1"
