Fixed Fastener Condition Calculator
Negative Tolerance numbers indicate interference. This calculator will calculate the unknown for the given conditions. Four (4) inputs
are required, See the application illustration at bottom of page. 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. Fastener (Shaft) Tolerance  The positional tolerance of the installed
bolt, screw or shaft. (Calculator does not compensate for projection zone). Hole Tolerance  This is the clearance hole positional
tolerance.
Clearance (C)  This is the clearance desired for the hole  fastener (shaft) when the holes are produced at a worst case positional
tolerance. This value is set to zero (0) for a line to line fit.
