Mechanical fitters fit and assemble metal pieces used in the manufacture of production machines and other equipment. They use a variety of tools and engineering approaches to keep mechanical plant machinery and equipment in good working order. They inspect and diagnose mechanical components or equipment that are damaged or worn. Mechanical fitters also employ precision measurement devices to ensure the correctness and fit of items.

Mechanical fitters may work in the trades and services industry, which is prevalent in Perth’s industrial regions, or in the mining industry, which is prevalent in locations such as the Pilbara, Kimberley, and Goldfields.
