What are shear nuts? These nuts are a rather rare type of nuts which are actually only used on components and machines where the shear nuts are only to be screwed on once and then break off. At this moment they are "disposable nuts" or "single use nuts". The shear nuts are screwed firmly to the component so that the nut is firmly connected to the work pieces. When the nut has passed the point of "tight", the breakaway follows when the nut is turned further. This means in plain language that the hexagonal guide of the breakaway nut remains, but at the predetermined breaking point of the breakaway nut "elegantly turns off" the connection between the hexagonal part of the nut, which has no thread whatsoever, and the "semicircular lower part", which is the actual threaded locking device, is inevitably separated! In this case, the connection is broken within the predetermined breaking point of the shear nut and thus the nut can no longer be gripped with a tool. The stainless steel shear nut is now firmly attached to the Beuteil, but without the hexagonal part for the movement. Due to the semicircular shape of the torn off hexagon nut, it is no longer possible to grip the nut, as the tool - a pair of pliers - slips over the shape of the shear nuts and there is no longer a clean cylindrical contact surface. This is how the shear nut does its job and it becomes a locknut in a certain sense, which can no longer be opened easily. This screw connection prevents existing assemblies from being opened or dismantled unintentionally! If you would like to read more details about stainless steel shear nuts, please visit our blog.

Design of the shear nut and function
We would like to explain to you briefly how exactly a shear nut made of stainless steel is constructed. The shear nut has a part which is round without edges and borders on a predetermined breaking point. Behind the predetermined breaking point of the shear nut is the part which can hold the tools, for example the open-ended spanner. When the nut is tightened, the tool is turned further to "overtighten" the nut, i.e. the part with the spanner flats, which is now separated from the lower part of the nut. Afterwards only the part of the shear nut remains, which holds the thread and can hold the components together. Due to the shape of the torn off nut (its upper part) it is not possible to open the nut again without special tools. The screw connection is effectively protected against unintentional opening. To undo a shear nut again is of course problematic, because that is exactly the reason why this nut was built this way. To prevent or prevent loosening. Now of course you have no more contact surface to which you can attach the pliers, but that is no problem at all if you know the tricks to loosen this shear nut again in a few minutes. You need a flex with which you cut two wrench flats on the opposite side of the torn off nut. These do not have to be exact or precise, just so that you have a way to get the pliers securely in place and grip again. Now unscrewing the shear nut should not be a problem anymore.
