About this Fitter practice test
ITI Fitter trade theory is part of the CBT along with Workshop Calculation and Science, Engineering Drawing and Employability Skills. This set practises the theory that runs through both years: safety, vernier and micrometer reading, marking, filing, sawing, drilling, tapping and reaming, threads and fasteners, limits and fits, heat treatment, bearings and assembly.
The questions were written for this page; none is copied from NIMI or a question bank. Every calculation was checked before publishing, and the answers show the working.
