Rob, the cost differential seems to revolve mostly around application process differences that save manufacturing costs and time, which also translate into cost. But your point is well taken--if the adhesives help the product last longer since it's not poking holes in sheetmetal--which will  make the metal fail sooner as well as creating a point of ingress for damaging liquids--then that's another cost savings.

Given all this, I would imagine we will see more and more adhesives on our products. Are there particular industries that are adopting this? Are there certain industries in which the adoption of adhesives is a particularly strong solution?

Jim makes a good point.  Adhesives can resist as much load as mechanical fasteners -- provided that you have enough surface area to spread them over.  But since, in round numbers, the shear strength of steel is 100 times greater than the shear strength of typical structural adhesives, this means you need to have 100 times more surface area.  It might not be hard to find this much surface area on a large component, but on a small component, it could be a challenge.

Where adhesives really shine is in fatigue -- and since, in my experience, most fastener failures are fatigue failures, this can be a big advantage.  Also, as Tom Drechsler points out, if adhesives are properly used, they can vastly simplify a manufacturing process.

Jim, Tom, and Dave: Thanks, guys, for the detailed feedback and your collective experience. The advantages of one over the other obviously depend on the specific circumstances. The big advantage I kept hearing about adhesives was simplification and therefore reduction of manufacturing times, thus savings. I will keep all this in mind when I work on the micro-fastener feature. Your feedback will help me ask better questions!
