I need to thread tap my bumpers (M12 1.5) to clean out the rust. Is there a socket or extension that works with these? I did the rear bumper with a 8mm socket but it's slipping on the front bumper not being a perfect fit and as the rust is a little tougher.
If very much possible without spending $40 on a socket set that I'll never use again! Thanks! |

You need a basic collet tap wrench like this...

I have had really good luck just going to the hardware store and buying a long(er) grade 8 bolt and cutting 2 grooves in it using a cut off grinder or even a hacksaw, and using as a cleaner / chaser .
Good lube, and screw in then back out (clean if needed) the repeat. |

What I usually do is find a nut that's a little smaller than the square drive of the tap, hammer it on and use a 1/4 drive ratchet/socket to turn it. A little crude but it works.

You'll do better with a thread chase, not a tap. A tap will cut the threads a little larger making a loose fitting bolt.

I actually used the same style nut that goes on the clutch pulley. It fit perfect.
