Yes, you can bring a screwdriver on a plane, but the size determines where it goes. Screwdrivers 7 inches and under (measuring the entire tool, handle included) are allowed in carry-on. Screwdrivers over 7 inches must go in checked baggage. This applies to all tool types, including flathead, Phillips, Torx, and multi-bit sets.
There’s no restriction on screwdrivers in checked baggage regardless of size.

TSA’s 7-Inch Rule for Tools
TSA’s official rule: tools 7 inches or less (measured with the handle) are allowed in carry-on. Tools over 7 inches must be in checked baggage. This covers screwdrivers, wrenches, pliers, and similar hand tools.
What “7 inches” means in practice:
- A standard pocket screwdriver (4 to 5 inches): carry-on fine
- A small multi-bit kit (under 7 inches folded): carry-on fine
- A full-size flathead or Phillips driver (8 to 12 inches): must go checked
- A precision screwdriver set with individual drivers under 7 inches: carry-on fine
If you’re not sure about a specific driver, measure it from tip to end of handle before you pack.
Carry-on vs Checked: Which Is Better?
If your screwdriver is small enough to go either way, carry-on is usually the smarter choice for a few reasons:
- Access at destination. If you need it for a project immediately on arrival, carry-on means you have it without waiting for bags.
- Less risk of loss. Checked bags occasionally get lost or delayed. A tool in checked means you might arrive without it.
- Security screening. Small tools in carry-on tend to pass X-ray quickly. Packing them in a clear bag or separate case makes the agent’s job easier.
For heavy tools or full tool sets, checked is the only option anyway (most sets include drivers longer than 7 inches).
Packing Tips for Screwdrivers in Carry-on
- Put tools in a clear pouch. If the agent wants to inspect them, a clear bag makes it faster. You can hand the whole pouch over without digging through your bag.
- Cap or sleeve the tip. Loose screwdrivers with exposed tips occasionally get flagged for their pointy end. A rubber tip cap or the original plastic sleeve prevents this.
- Keep it accessible. You don’t need to remove screwdrivers from your bag at security (they’re not like electronics). Just make sure they’re not hidden under a laptop or other electronics that need to come out.
Other Tools on Planes: Quick Reference
- Wrench/pliers: Same rule as screwdrivers. 7 inches or under in carry-on, over 7 inches in checked.
- Drills (battery-powered): Must go in checked. Both the drill body and the spare lithium battery fall under specific airline rules for lithium batteries.
- Box cutters/utility knives: Must go in checked. No exceptions for size.
- Multi-tools with a knife blade: Must go in checked because of the blade.
- Multi-tools without a knife: Allowed in carry-on if under 7 inches.
- Hammers: Must go in checked. TSA explicitly restricts hammers from carry-on regardless of size.
- Cordless drill batteries (lithium): Must travel in carry-on, not checked (same as other lithium batteries).
International Flights
US-originating rules apply at the departure airport. When flying internationally, some countries have stricter rules about tools in carry-on. UK and EU airports generally follow a similar policy to TSA, but individual agents can exercise discretion. If you’re flying through a strict security system (like some Middle Eastern or Asian airports), pack tools in checked to avoid questions.
Frequently Asked Questions
Can I bring a screwdriver in my carry-on bag?
Yes, as long as the total length (including handle) is 7 inches or under. Screwdrivers over 7 inches go in checked baggage.
Can I bring a multi-bit screwdriver set on a plane?
If the drivers in the set are each under 7 inches, yes. If the kit includes a full-length driver over 7 inches, that piece needs to go in checked. Precision screwdriver sets (with small electronics drivers) are almost always under the limit.
Can TSA still confiscate a screwdriver under 7 inches?
Yes. TSA agents have final say at the checkpoint. A screwdriver within the size limit can still be flagged if an agent considers it a security risk. This is rare but it does happen, especially for unusually sharp or pointed tips.
Can I bring a screwdriver in checked baggage?
Yes, any size screwdriver is allowed in checked baggage with no restrictions. Wrap or sheathe the tip to protect your bag and the baggage handler.
