They have a similar structure to bolts. However, they do not need anything to keep them in place, unlike bolts. Nuts: A nut comes with an internal thread that works with a bolt to hold components together. Washers: They are small, circular discs shaped like an annulus.

WebSafety factors need only be applied to external loads. 4 Bolt Preload. A critical component of designing bolted joints is not only determining the number of bolts, the size of them, and the placement of them but also … WebThe margin of safety for a fastener from figure 31 is $$ MS = { 1 \over R_S^x + R_T^y } - 1 $$ ... If the threads were perfectly mated, this factor would be 1/2, since the total cylindrical shell area of the hole would be split equally between the bolt threads and the tapped hole threads. The 1/3 is used to allow for mismatch between threads.
