Z121S Lawn Mover bolt for Blade broke off in the Final Drive

And they actually make a M12-1.00. So all I needed here is the 1.25 and 1.50 pitches.

The bolt - just purchased is a M12 x 1.25 x 30 I have not done many of these. I am not trying to drill out and re tap. I would like to use the correct tap and hopefully clean up the threads. What is the correct tap needed? is it the M12 x 1.25? What is the 30? it looks like pretty fine treads. Tom

I hate to ask this but just how dense are you? A M12-1.25 uses a M12-1.25 tap or die ( the screw itself would need a die and the hole it goes in takes a tap. Since this is a blind hole hole you need a bottoming tap to reach the bottom but you need a taper or plug tap to get started. Most stand length in this size nearly 40mm long and your screw is only 30mm long.

Two of these from my vendor is only $60 plus shipping.
