Fixed fastener formula example
WebJun 18, 2008 · Hi all. I have a doubt regarding the allocation of the positional tolerance using "Fixed Fastener Formula" mentioned in the ASME Y14.5. The formula says that the allowable tolerance i.e. difference between the MMC of the fastener and the MMC of the hole is being equally divided and allocated to the clearabce part and the threaded part. http://home.eol.ca/~hgibson/tolerances.pdf

WebFastener (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 … WebFasteners pass through clearance holes in both parts. The obvious example of this is a nut and bolt assembly, but this could also be a cotter pin assembly or a pre-drilled rivet assembly. The bolts could be clamping more than two parts at a time. See Figure 1 . It will be assumed for analysis purposes, that bolts are located precisely at their
WebFeb 26, 2024 · An example might be for a hole whose fastener doesn’t protrude very far up — such as a bolt that engages the threads for 16 mm but then clears through an adjacent plate of only 4 mm thickness. But in general, a designer should at least consider the “P” option when imposing GD&T on threaded or press-fit holes.
