Thread Inspection Specialist (TIS) TIS probes beyond surface-level fastening knowledge into metallurgical stress analysis, pitch accuracy tolerances measured to microinches, and failure mode prediction under cyclic loading. Examiners expect you to distinguish between galling, seizing, and hydrogen embrittlement in real inspection scenarios? not just define them. Most candidates underestimate the physics required.
