<p class="p__0">You can expect the bolt to break in a few thousand cycles if the fatigue load has to do with 80% (+/ -10%) of the supreme fixed load. (Note: the precise portion can vary drastically based upon product composition and ambient conditions.) There is a common misconception that a bolt within a firmly secured connection is invulnerable to outside forces if hey don't go beyond the clamped load of the connection.</p>
<br>
<p class="p__1">This is not so!.?.!! In fact ANY extra load, no matter how little, will contribute to the tension in the bolt. However not at a 1:1 rate. Think about pulling on a fastened connection as if it were 2 stacked springs. Both springs stretch measurably, however the weaker one stretches more.</p>

<p class="p__2">To be crystal clear, as you tighten up the nut the bolt will compress the two parts together. The bolt itself has an internal response force equivalent to the amplitude of the compression force, but the bolt itself is in tension. If you were to chart the tension on the bolt while you tighten up the nut, the plot would look like the graph below.</p>

<p class="p__3">Any more force and the bolt will enter the plastic area and completely warp. In practice engineers don't create that method. Since any extra force will start to yield the bolt, you wish to offer yourself some margin for mistake. Engineers select a bolt stress that is someplace in between the calculable minimum practical securing force and the yielding force.</p>

<br>
<p class="p__4">( Sources: Shingley's Basic Handbook &amp; Article on Fastenal) We now understand how essential it is to avoid over tightening a bolt, however how do we know when it is yielding? For Superior Washer clamping force can be estimated by measuring the tightening torque. You can look up the recommended tightening up torque for a provided fastener size in my bolt sizing calculator or in a table like the one discovered here.</p>
<br>
<p class="p__5">Those techniques work OK for most things, however some crucial applications require you to be specific of the securing force (think spacecraft or big weights above your head). The torque approach has difficultly representing friction and lubrication, however at least the torque is mathematically correlated to the clamping force.</p>
