01The rules in detail
TSA allows small screwdrivers, wrenches and pliers up to 7 inches in the cabin; anything longer, plus power tools, saws, hammers, drills and drill bits, goes in checked bags. The EU, UK and most of Asia are stricter and prohibit tools of any size in carry-on (‘tools that could cause serious injury’). Power-tool batteries follow lithium rules — cabin only, terminals protected.
02Tips
- Outside the US, check all tools.
- Remove lithium batteries from power tools and carry them on.
03Frequently asked
Can I bring tools in my carry-on?

Can I pack tools in checked luggage?
Yes. US: tools 7 inches (18 cm) or shorter are allowed in carry-on; longer tools, drills, saws, crowbars and hammers must be checked. Most other countries ban all tools from the cabin — check them.
Are the rules the same outside the US?
Mostly similar for liquids and batteries, which follow international standards, but sharp objects, tools, lighters and self-defense items vary widely by country. Check the departure airport's rules and the destination's laws.
TSA and other agencies allow officers to refuse any item they judge unsafe, and rules change. This page summarises published guidance as of the verified date; confirm on tsa.gov or your airport's site before packing anything unusual.
