Interpretation and Application of
Geometric Dimensioning and Tolerancing
This calculator will determine the unknown variable of a floating fastener design condition using ASME Y14.5 - 2009 and ISO 1101 and derivative GD&T standards.
Negative Tolerance Numbers Indicate an Interference Condition
This calculator will calculate the unknown for the given conditions.
Two (2) inputs are required,& See the application illustration at bottom of page.
Open Floating Fastener Condition Tolerance Calculator
The following are definitions for the elements:
Fastener (Shaft) Diameter - This is the maximum size (MMC) of the bolt, shaft or other feature of size.
Hole Diameter - This is the smallest hole (MMC) for the given feature of size.
TOL = Hole Tolerance, This is the hole positional tolerance applied to all related hole features.
Applies to both plates #1 and #2.
