The special role of anaerobic adhesives in mechanical engineering

Anaerobic adhesives were created specifically for assembling a wide variety of mechanical engineering components. The impact their properties and use have on fundamental design concepts is discussed in relation to other types of adhesives in Chapter 2. What this approach does not demonstrate is the overall value of these unique materials to the mechanical engineer in a wide range of situations, nor does it show the degree to which the characteristics of individual grades are matched to the intended end use. 

As will be readily appreciated, the vast majority of fitted mechanical components are co-axial, so it is convenient to subdivide this group into smooth and splined co-axial components, and then further into threaded parts or fasteners.

Anaerobics have been found to extend the working life of splined joints -including keys and key ways - since they ensure that assembly does not cause distortion and that the imposed loads are evenly distributed. Typical applications are drive shafts on light cars and heavy vehicles alike and the securing of pump gears.
