Geometric Dimensioning and Tolerancing for Mechanical Design Answer Guide 46 Chapter 8 Position, Location Chapter Review Page 153 1. The floating fastener formula is: T = H – F or H = F + T 2. T = The clearance hole Location Tolerance at MMC H = The Clearance Hole MMC diameterF = The Fastener’s MMC diameter, the nominal size3. The clearance hole LMC diameter formula isH @ LMC = (F +F head) / 2. 4. The fixed fastener is fixed by one or more of the members being fastened. 5. The formula for fixed fasteners is: t1+ t2= H – F or H = F + t1+ t2 6. The location tolerance for both the threaded hole and the clearance hole must come from the difference between the actual diameter of the clearance hole and the diameter of the fastener . 7. It is common to assign a larger portion of the tolerance to the threadedhole.
