GD&T Fixed Fastener Condition Projected Tolerance Zone Compensation Calculator
This calculator will calculate the required field compensating for the effects of the fastener projection. Calculations assume a lineline case at tolerance and featureofsize
maximum departure.
Note: All fields require an input except field being calculated. Four (5) 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. Hole Tolerance  This is the clearance hole positional
tolerance @ MMC. Projected Tolerance Zone  This is the distance that the fastener (shaft) extends beyond the hole which it is installed
within. This compensates for the effects of the shaft distance. (Projected tolerance zone is very important when significant shaft length must be compensated for. Thread or Shaft Engagement  This is the minimum distance of fastener or shaft engagement into the fixed component.
