Nah I'm actually just looking to offset two rows of taps on a mounting panel, having longer shanks on the top row taps fixed at the back of the shank rather than the front so they protrude past the lower row. I think I can make it work with the 100mm ones well enough but thought I'd ask just in case they were available to get more of a difference between the two rows.
This leads into the push-in tail question, your suggested solution is probably what I'll go with but I was hoping to have a metal fitting at the back of the shank to tighten against the board (lock nut on the front) rather than a plastic duotight fitting.
Re the nukatap FC I didn't mean to suggest it wasn't a real part, just whether it was a real ETA or just a placeholder date.
Thanks for the responses
With regards to the Nukatap FC I think the arrival date for this would be about Mid July. When the date gets closer we will update the website but this is our best guess at this stage.
