Fixed fastener formula example
WebFixed Fastener Case When Projected Tolerance Zone Is Used. Equation 1a and 1b should be used with an explicit projected tolerance zone identified in the feature control frame. Equation 1a assumes the threaded and the corresponding clearance holes have the same position tolerance. WebNearly all assemblies fall into the categories of either fixed or floating features. A floating feature assembly might be a shaft floating within two bushings. Where a part floats between multiple features, the floating fastener formula will usually apply. The ASME Y14.5M-1994 standard gives the floating fastener formula as H = F + T where ...
