Subsequent Events [Abstract]
Subsequent Events	Subsequent EventsThe challenges posed by the COVID-19 pandemic on the global economy increased significantly as the first quarter progressed, impacting Snap-on’s sales volumes in most geographies and across a variety of customers, including those in automotive repair. COVID-19 has spread across the globe during 2020 and is impacting economic activity worldwide. In response to COVID-19, national and local governments around the world have instituted certain measures, including travel bans, prohibitions on group events and gatherings, shutdowns of certain businesses, curfews, shelter-in-place orders and recommendations to practice social distancing. The ultimate impact of COVID-19 on our business, results of operations, financial condition and cash flows is dependent on future developments, including the duration of the pandemic and the related length of its impact on the global economy, which are uncertain and cannot be predicted at this time.
