(quoted from post at 12:58:23 10/06/23) need to drill a hole for a 14m bolt...would that be 35/64?

I'd use a 9/16" bit.

14mm=.551 35/64=.547 9/16=.562 Your choice 1. try to beat it in or 2 slip it in with clearance.

You probably meant 14mm, not 14 meters. 14 mm is .551", and 35/64 is .546", which would require a hammer. I"d go with 9/16", which is .562".

9/16 Would be easier to find, but 35/64 works tighter. Jim

Is 14mm the thread diameter or the size of the wrench you need to turn it with?

 

[rustred]

Easy, stick that bolt in the standard drill index and pick the drill bit for the hole.

 

[Stephen Newell]

It would be a little more than that. If you need the hole close to the bolt size I would drill a 9/16 hole. Not knowing what you are doing I would be more inclined to drill a 5/8 hole.

Are you tapping it to 14mm or passing a 14mm bolt through the hole?

 

[caterpillar guy]

By the looks of it if you want ti to work like a stud then the 35/64ths. If you want it to work like a cap screw with a nut then the 9/16ths. OR just use a half inch bolt and be done with it.

If you want to drill and tap 14mm threads, the drill size depends on the thread pitch. There are good tap drill charts available to look at, just google it.

Mike .... if you reply to some of the questions you might get an answer that you want.
