Thin-walled materials are often selected to reduce weight and costs. In practice, however, issues frequently arise at the fastening stage. The root cause is rarely the material itself, but design decisions that do not sufficiently account for limited wall thickness.
Common design mistakes include:
โถ Insufficient thread engagement
โถ Relying on weld nuts or press nuts without analyzing process impact
โถ Failing to account for deformation during assembly
โถ Edge distances or center-to-center distances that are too small
โถ No alignment between design and manufacturability
When the appropriate fastening method is considered during the design phase, thin-walled material can be used structurally without additional components or secondary operations.
With friction drilling, the material is plastically deformed to create a bushing, locally increasing the effective material thickness up to approximately three times. This provides sufficient thread engagement in thin material without the need for weld nuts or press nuts.
