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.
