How Do You Calculate the Maximum Bolt Angle Through a Flanged Hole?

Click For Summary

Discussion Overview

The discussion revolves around calculating the maximum angle at which a bolt can pass through a flanged hole, given specific parameters such as flange thickness, bolt hole diameter, and bolt diameter. The focus is on the theoretical and practical aspects of this calculation.

Discussion Character

  • Technical explanation, Conceptual clarification, Exploratory

Main Points Raised

  • One participant inquires about a formula to calculate the maximum angle for a bolt passing through a flanged hole based on known dimensions.
  • Another participant suggests that drawing a diagram may simplify understanding the problem and help in deriving the angle.
  • A later reply indicates that visualizing the problem through a drawing clarified the situation for the original poster.
  • Another participant mentions that trigonometry could be useful in this context and notes that counter-sinks on the hole may significantly affect the maximum angle.

Areas of Agreement / Disagreement

Participants do not reach a consensus on a specific formula or method, and multiple approaches to understanding the problem are presented.

Contextual Notes

There may be limitations related to the assumptions made about the geometry of the hole and bolt, as well as the potential impact of counter-sinks, which are not fully explored in the discussion.

I have a flange of known thickness, with a bolt hole of a known diameter through it. I am trying to calculate the maximum angle off from the centerline through the bolt hole that the bolt will be able to pass ( I know the max diameter of the bolt as well ). Is there a formula for this, given that I know the flange thickness, bolt hole diameter, and bolt diameter? Thanks in advance.

I would just draw a picture.
You have a striaght hole of known width and depth, a straight bolt of known width.
The angle should come out easily - probably more easily than describing the question.
 
Thanks. Yeah, as soon after I posted this, I drew it out and it became a lot clearer :)
 
Yup, trig = friend :cool: Counter-sinks on the hole can also have a large effect on max angle, so you might look into that.
