Question on thread size?

[SpiritRider]

I messed up on assembling a rifle pen kit.

I am thinking about running a bolt in and pull the brass insert but can't find anything that fits.I believe it to be a m8 but I don't know what pitch.
Any idea?

I am assuming it is because the Tip Assembly was pressed in upside down?

Rather than flipping the Tip Assembly over, to fix it I would flip the Lever Mechanism Assembly over. This can be done by unscrewing the tip, removing the spring and ink and using the largest disassembly punch (transfer punch) that will fit through the Tip Nut hole to tap out the Lever Mechanism Assembly. Then flip the Lever Mechanism Assembly over and press it back in. Good Luck on your repairs. - Dave

PS The other option would be to use a larger disassembly punch after the Lever Mechanism Assembly is out to tap out the Tip Nut. Then you can re-assemble both pieces back onto the blank.

The last time I tried that I messed up the mechanism. That's why I was thinking about the insert.

Yes - That's a pretty expensive kit to damage. - Dave
