Bolt Hole Locator For A Hole At 45 Degree TangentS

 

Bolt Hole Locator Constants
45 Degree Locations

Lets say you need to find the location of a hole that is at a 45 Degree tangent  from the center of a bolt hole pattern.

For all general purposes, this chart is for a threaded hole or a clearance hole that a bolt is going to go
through that needs a little space to be threaded into another part.

The chart is good for X and Y axis since the placement at 45 degrees, is for all practical purposes, is equal.

The original calculation is in 5 places as seen in the formula.

I rounded off the 4th place by dropping off the 5th place for ease of use.

Please Note:
If you need a location for a hole that is going to have a pin in it or is going to be reamed or bored out
and the exact location is needed, you might want to use a different calculation since these types of holes
are much more accurately located.

Please go to my other chart on Bolt Hole Constants at:

Look for the 8 hole pattern and use its formula.
