How do you find the size thread (metric) that has been tapped into a drilled hole? Buy assortment of of metric thread bolts and try till one fits?
Thanks, BravoCharlie |

Its much simpler than that.
Simply go to most auto stores, hardware stores, or machine shop supply houses and buy a metric screw thread gage. This is a gage with threaded holes and studs that are labeled as to what thread they are. Here's a good set. One side of the ball has a threaded stud that gages a hole, the hole in the ball gages the screw itself. http://www.rockler.com/product.cfm?page=21999 Many hardware stores have gages chained to the wall in the screw department for customers to use. Unless its a receiver or too big, just take the part to a good hardware store that spells metric screws and they'll gage it for you. |

This right here, for inside threads, for out side threads the wires are your friends,as always. |

If push comes to shouve, you can mrasure the thread wirh an inside mike and some bearings of known dianeter,,,,,,, I didn't say it was easy, but itt;s posible. Thread wires and mic should provide a pretty damn good idea too. Not going to have much luck with thread wires on an inside thread. |
